Granulocyte colony-stimulating factor plus pentoxifylline increases short-term survival in patients with severe alcoholic hepatitis: a network meta-analysis. THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2024; 50:191-206. [PMID: 38011683 DOI: 10.1080/00952990.2023.2266117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 09/28/2023] [Indexed: 11/29/2023]
Abstract
Background: Optimal treatments for severe alcoholic hepatitis (SAH) remain controversial. Previous network meta-analysis showed that corticosteroid (CS) combined with N-acetylcysteine (NAC) was superior in reducing short-term mortality of patients with SAH. Recently, granulocyte colony-stimulating factor (G-CSF) treatments for SAH yielded promising results.Objectives: To determine how currently available treatments affect the survival and complications of patients with SAH.Methods: The study was conducted following the guidelines of PRISMA. The data from PubMed, Embase, MEDLINE, Cochrane Library, and clinicaltrials.gov to October 2022 were searched, and patients with SAH with pharmacotherapy were included in our study. The primary outcome was short-term survival, and the other outcomes were medium- (3/6 months) or long-term (12 months) survival and complications after treatment. R software was used to establish network meta-analysis models and the result was expressed by the odd ratio (OR) value and 95% credible interval (Crls).Results: A total of 31 randomized controlled trials, including 19 treatment regimens, were enrolled in our study. As the primary outcome, G-CSF+ pentoxifylline (PTX) ranked first in one-month survival and showed significant superiority when compared with the placebo (OR 8.60, 95% Crls 1.92-45.10) and CS (OR 4.95, 95% Crls 1.11-25.53). Also, G-CSF+PTX ranked first in improving three-month survival and reducing the occurrence of infection. PTX+MTD ranked first in six-month survival, and G-CSF ranked first in twelve-month survival. CS+MTD ranked first in the occurrence of gastrointestinal bleeding and hepatorenal syndrome.Conclusions: The combination of G-CSF and PTX showed a significant benefit in improving the short-term survival of SAH patients.

Abstract
BACKGROUND AND OBJECTIVES The safety and efficacy of granulocyte-colony stimulating factor (G-CSF) for the treatment of acute-on-chronic liver failure (ACLF) remain controversial. This meta-analysis aimed to evaluate the effectiveness and safety of G-CSF in treating ACLF. METHODS The estimated pooled risk ratio (RR) and 95% confidence interval (CI) assessed the treatment effects of G-CSF. Mean differences (MD) and 95% confidence intervals were used to analyze continuous data. Heterogeneity was explored by sensitivity analysis. Potential publication bias was assessed using Egger's test. RESULTS Ten studies, comprising a total of 603 participants, were included in the analysis. The G-CSF group showed significantly lower MELD scores at 7-day (MD = -2.39, 95%CI: -3.95 to -0.82), CTP scores at 7-day (MD = -0.77, 95%CI: -1.41 to -0.14), and MELD scores at 30-day (MD = -3.01, 95%CI: -5.36 to -0.67) compared to the control group. Furthermore, the G-CSF group was associated with a reduced risk of sepsis (RR = 0.53, 95%CI: 0.35-0.80). The 30-day survival (RR = 1.26, 95%CI:1.10-1.43), 60-day survival (RR = 1.47, 95%CI:1.17-1.84, and 90-day survival (RR = 1.73, 95%CI: 1.27-2.35) of patients with ACLF treated with G-CSF were significantly higher than those of the control group. CONCLUSIONS Our meta-analysis suggests that G-CSF therapy may be a promising treatment for ACLF, with significant improvements in liver function and survival rates, however, further studies are needed to verify this conclusion.

Abstract
The socioeconomic burden of alcohol-related liver disease has been increasing worldwide. Its prevalence is underestimated, and patients with alcohol-related liver disease are rarely diagnosed in the earlier phase of the disease spectrum. Alcoholic hepatitis is a distinct syndrome with life-threatening signs of systemic inflammation. In severe alcoholic hepatitis, prednisolone is indicated as the first-line treatment even with the possibility of various complications. Early liver transplantation can be another option for highly selected patients with a null response to prednisolone. Most importantly, abstinence is the mainstay of long-term care, but relapse is frequent among patients. Recent findings on the pathogenesis of alcoholic hepatitis have enabled us to discover new therapeutic targets. Preventing hepatic inflammation, reducing oxidative stress, improving gut dysbiosis, and enhancing liver regeneration are the main targets of emerging therapies. Herein, we review the pathogenesis, current treatment, and barriers to successful clinical trials of alcoholic hepatitis. Additionally, clinical trials for alcoholic hepatitis, either ongoing or recently completed, will be briefly introduced.

Abstract
Severe alcoholic hepatitis (AH) is a distinct entity in the spectrum of alcohol-related liver disease, with limited treatment options and high mortality. Supportive medical care with corticosteroids in selected patients is the only currently available treatment option, often with poor outcomes. Based on the insights into the pathogenetic mechanisms of AH, which are mostly obtained from animal studies, several new treatment options are being explored. Studies have implicated impaired and deranged liver regeneration processes as one of the culprit mechanisms and a potential therapeutic target. Acknowledging evidence for the beneficial effects of granulocyte colony-stimulating factor (G-CSF) on liver regeneration and immunomodulation in animal models, several human studies investigated its role in the treatment of advanced alcohol-related liver disease and AH. Contrary to the previously published studies suggesting benefits of G-CSF in the outcomes of patients with severe AH, these effects were not confirmed by a recently published multicenter randomized trial, suggesting that other options should rather be pursued. Stem cell transplantation represents another option for improving liver regeneration, but evidence for its efficacy in patients with severe AH and advanced alcohol-related liver disease is still very scarce and unconvincing, with established lack of efficacy in patients with compensated cirrhosis. In this review, we summarize the current knowledge on the pathogenesis and experimental therapies targeting liver regeneration. The lack of high-quality studies and evidence is a major obstacle in further treatment development. New insights into the pathogenesis of not only liver injury, but also liver regeneration processes are mandatory for the development of new treatment options. A reliable experimental model of the pathogenesis of AH and processes involved in liver recovery is still missing, and data obtained from animal studies are essential for future research.

Liver Regeneration by Hematopoietic Stem Cells: Have We Reached the End of the Road? Cells 2022; 11:cells11152312. [PMID: 35954155 PMCID: PMC9367594 DOI: 10.3390/cells11152312] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 07/22/2022] [Accepted: 07/22/2022] [Indexed: 02/01/2023] Open
Abstract
The liver is the organ with the highest regenerative capacity in the human body. However, various insults, including viral infections, alcohol or drug abuse, and metabolic overload, may cause chronic inflammation and fibrosis, leading to irreversible liver dysfunction. Despite advances in surgery and pharmacological treatments, liver diseases remain a leading cause of death worldwide. To address the shortage of donor liver organs for orthotopic liver transplantation, cell therapy in liver disease has emerged as a promising regenerative treatment. Sources include primary hepatocytes or functional hepatocytes generated from the reprogramming of induced pluripotent stem cells (iPSC). Different types of stem cells have also been employed for transplantation to trigger regeneration, including hematopoietic stem cells (HSCs), mesenchymal stromal cells (MSCs), endothelial progenitor cells (EPCs) as well as adult and fetal liver progenitor cells. HSCs, usually defined by the expression of CD34 and CD133, and MSCs, defined by the expression of CD105, CD73, and CD90, are attractive sources due to their autologous nature, ease of isolation and cryopreservation. The present review focuses on the use of bone marrow HSCs for liver regeneration, presenting evidence for an ongoing crosstalk between the hematopoietic and the hepatic system. This relationship commences during embryogenesis when the fetal liver emerges as the crossroads between the two systems converging the presence of different origins of cells (mesoderm and endoderm) in the same organ. Ample evidence indicates that the fetal liver supports the maturation and expansion of HSCs during development but also later on in life. Moreover, the fact that the adult liver remains one of the few sites for extramedullary hematopoiesis—albeit pathological—suggests that this relationship between the two systems is ongoing. Can, however, the hematopoietic system offer similar support to the liver? The majority of clinical studies using hematopoietic cell transplantation in patients with liver disease report favourable observations. The underlying mechanism—whether paracrine, fusion or transdifferentiation or a combination of the three—remains to be confirmed.

Granulocyte Colony-Stimulating Factor Treatment Before Radiotherapy Protects Against Radiation-Induced Liver Disease in Mice. Front Pharmacol 2021; 12:725084.

Abstract
Radiation-induced liver disease (RILD) remains a major problem resulting from radiotherapy. In this scenario, immunotherapy with granulocyte colony-stimulating factor (G-CSF) arises as an attractive approach that might improve the injured liver. Here, we investigated G-CSF administration’s impact before and after liver irradiation exposure using an association of alcohol consumption and local irradiation to induce liver disease model in C57BL/6 mice. Male and female mice were submitted to a previous alcohol-induced liver injury protocol with water containing 5% alcohol for 90 days. Then, the animals were treated with G-CSF (100 μg/kg/d) for 3 days before or after liver irradiation (18 Gy). At days 7, 30, and 60 post-radiation, non-invasive liver images were acquired by ultrasonography, magnetic resonance, and computed tomography. Biochemical and histological evaluations were performed to verify whether G-CSF could prevent liver tissue damage or reverse the acute liver injury. Our data showed that the treatment with G-CSF before irradiation effectively improved morphofunctional parameters caused by RILD, restoring histological arrangement, promoting liver regeneration, preserving normal organelles distribution, and glycogen granules. The amount of OV-6 and F4/80-positive cells increased, and α-SMA positive cells’ presence was normalized. Additionally, prior G-CSF administration preserved serum biochemical parameters and increased the survival rates (100%). On the other hand, after irradiation, the treatment showed a slight improvement in survival rates (79%) and did not ameliorate RILD. Overall, our data suggest that G-CSF administration before radiation might be an immunotherapeutic alternative to radiotherapy planning to avoid RILD.

Abstract
End-stage liver disease (ESLD) is characterized by the deterioration of liver function and a subsequent high mortality rate. Studies have investigated the use of adult stem cells to treat ESLD. Here, a systematic review and meta-analysis was conducted to determine the efficacy of a combination therapy with adult stem cell transplantation and traditional medicine for treating ESLD. Four databases-including PubMed, Web of Science, Embase, and Cochrane Library-were investigated for studies published before January 31, 2021. The main outcome indicators were liver function index, model for end-stage liver disease (MELD) scores, and Child‒Turcotte‒Pugh (CTP) scores. Altogether, 1604 articles were retrieved, of which eight met the eligibility criteria; these studies included data for 579 patients with ESLD. Combination of adult stem cell transplantation with conventional medicine significantly improved its efficacy with respect to liver function index, CTP and MELD scores, but this effect gradually decreased over time. Moreover, a single injection of stem cells was more effective than two injections with respect to MELD and CTP scores and total bilirubin (TBIL) and albumin (ALB) levels, with no significant difference in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. With respect to the TBIL levels, patients receiving mononuclear cells (MNCs) experienced a significantly greater therapeutic effect-starting from twenty-four weeks after the treatment-whereas with respect to ALB levels, CD34+ autologous peripheral blood stem cells (CD34+ APBSCs) and MNCs had similar therapeutic effects. Severe complications associated with adult stem cell treatment were not observed. Although the benefits of combination therapy with respect to improving liver function were slightly better than those of the traditional treatment alone, they gradually decreased over time.Systematic review registration: PROSPERO registration number: CRD42021238576.

Abstract
Patients with acute-on-chronic liver failure (ACLF) have a devastating prognosis and therapeutic options are limited. Granulocyte-colony stimulating factor (G-CSF) mobilizes immune and stem cells and possess immune-modulatory and proregenerative capacities. In this review, we aim to define the current evidence for the treatment with G-CSF in end-stage liver disease. Several smaller clinical trials in patients with different severity grades of end-stage liver disease have shown that G-CSF improves survival and reduces the rate of complications. Adequately powered multicenter European trials could not confirm these beneficial effects. In mouse models of ACLF, G-CSF increased the toll-like receptor (TLR)-mediated inflammatory response which led to an increase in mortality. Adding a TLR4 signaling inhibitor allowed G-CSF to unfold its proregenerative properties in these ACLF models. These data suggest that G-CSF requires a noninflammatory environment to exert its protective properties.

Abstract
AIMS In RCT of adults with decompensated cirrhosis, GCSF mobilizes hematopoietic stem cells HSC and improves short-term outcome. An FDA-IND for sequential Kasai-GCSF treatment in biliary atresia BA was approved. This phase 1 study examines GCSF safety in Kasai subjects. Preliminary short-term outcome was evaluated. METHODS GCSF (Neupogen) at 5 or 10 μg/kg (n = 3/group) was given in 3 daily doses starting on day 3 of Kasai surgery (NCT03395028). Serum CD34+ HSC cell counts, and 1-month of GCSF-related adverse events were monitored. The 6-months Phase 1 clinical outcome was compared against 10 subsequent post Phase 1 Kasai patients who did not receive GCSF. RESULTS With GCSF, WBC and platelet count transiently increased, LFT and serum creatinine remained stable. Reversible splenic enlargement (by 8.5-20%) occurred in 5/6 subjects. HSC count increased 12-fold and 17.5-fold for the 5 μg/kg and10 ug/kg dose respectively; with respective median total bilirubin levels for GCSF vs no-GCSF groups of 55 vs 91 μM at 1 month, p = 0.05; 15 vs 37 μM at 3 months, p = 0.24); and the 6-months cholangitis frequency of 40% vs 90%, p = 0.077. CONCLUSIONS GCSF safely mobilizes HSC in Kasai infants and may improve short-term biliary drainage and cholangitis. Phase 2 efficacy outcome of GCSF adjunct therapy for sequential Kasai and GCSF is pending.

Abstract
The pathogenesis involving non-alcoholic fatty liver disease (NAFLD) in the context of chronic HBV (CHB) virus infection requires to be understood for developing improved modalities of diagnosis and treatment. We retrospectively investigated the association between NAFLD and CHB virus infection in the context of liver fibrosis. Among the 522 consecutive CHB patients who underwent transient elastography between years 2013 and 2016, we studied 455 subjects in the current investigation. Controlled attenuation parameter (CAP) and liver stiffness measurement (LSM) scores were generally higher in patients with steatosis and fibrosis or cirrhosis. Antiviral treatment had significantly reduced the hepatitis B virus (HBV) viral load. Other liver function markers showed a significant positive correlation with both CAP and LSM scores. Plasma IL-13 was independently associated with increased CAP score where every increase of 1 unit of IL-13 was associated with an increase in CAP score by 0.98 unit. CCL11 was independently associated with LSM with every increase of CCL11 by a unit that, in turn, was associated with an increase of LSM score. We found that there was a high concurrence of NAFLD among patients with CHB virus infection. The presence of metabolic syndrome and chronic inflammation in CHB virus-infected patients were two independent factors that led to the progression of liver cirrhosis, with IL-13 playing the key role in linking the metabolic with the inflammatory components.

Advantages of adipose tissue stem cells over CD34 + mobilization to decrease hepatic fibrosis in Wistar rats. Ann Hepatol 2020; 18:620-626. [PMID: 31147180 DOI: 10.1016/j.aohep.2018.12.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Revised: 12/04/2018] [Accepted: 11/01/2018] [Indexed: 02/06/2023]
Abstract
INTRODUCTION AND OBJECTIVES Chronic liver inflammation may lead to hepatic cirrhosis, limiting its regenerative capacity. The clinical standard of care is transplantation, although stem cell therapy may be an alternative option. The study aim was to induce endogenous hematopoietic stem cells (HSCs) with granulocyte colony stimulating factor (G-CSF) and/or intravenous administration of adipose tissue-derived mesenchymal stem cells (MSCs) to decrease hepatic fibrosis in an experimental model. MATERIAL AND METHODS A liver fibrosis model was developed with female Wistar rats via multiple intraperitoneal doses of carbon tetrachloride. Three rats were selected to confirm cirrhosis, and the rest were set into experimental groups to evaluate single and combined therapies of G-CSF-stimulated HSC mobilization and intravenous MSC administration. RESULTS Treatment with MSCs and G-CSF significantly improved alanine amino transferase levels, while treatment with G-CSF, MSCs, and G-CSF+MSCs decreased aspartate amino transferase levels. Hepatocyte growth factor (HGF) and interleukin 10 levels increased with MSC treatment. Transforming growth factor β levels were lower with MSC treatment. Interleukin 1β and tumor necrosis factor alpha levels decreased in all treated groups. Histopathology showed that MSCs and G-CSF reduced liver fibrosis from F4 to F2. CONCLUSIONS MSC treatment improves liver function, decreases hepatic fibrosis, and plays an anti-inflammatory role; it promotes HGF levels and increased proliferating cell nuclear antigen when followed by MSC treatment mobilization using G-CSF. When these therapies were combined, however, fibrosis improvement was less evident.

Abstract
Background & Aims Granulocyte colony-stimulating factor (G-CSF) treatment has been proposed as a therapeutic option for patients with severe alcoholic hepatitis (AH). The aim of this study was to synthesise available evidence on the efficacy of G-CSF in AH. Methods This is a meta-analysis of randomised controlled trials evaluating the risk of death at 90 days and the risk of infection. Results Seven studies were included. Of a total of 396 patients, 336 had AH, 197 patients were treated with G-CSF, and 199 received placebo or pentoxifylline. In overall meta-analysis, G-CSF therapy was associated with a reduced risk of death at 90 days (odds ratio [OR] 0.28; 95% CI 0.09–0.88; p = 0.03). There was high heterogeneity between studies (p <0.001; I2 = 80%). Five studies were performed in Asia and 2 in Europe. In the subgroup analysis of studies performed in Asia, G-CSF was associated with a reduced risk of death (OR 0.15; 95% CI 0.08–0.28; p <0.001; heterogeneity: p = 0.5, I2 = 0%). In European studies, G-CSF tended to increase mortality compared with controls, although the difference was not significant (OR 1.89; 95% CI 0.90–3.98; p = 0.09; heterogeneity: p = 0.8, I2 = 0%). In Asian studies, occurrence of infection was less frequent in G-CSF patients than in controls (OR 0.12; 95% CI 0.06–0.23; p <0.001; heterogeneity: p = 0.7, I2 = 0%), whilst in European studies, this occurrence was not statistically different (OR 0.92; 95% CI 0.50–1.68; p = 0.78; heterogeneity: p = 0.5, I2 = 0%). In sensitivity analyses, excluding studies that included patients with acute-on-chronic liver failure (ACLF) other than AH, patients with less severe AH, or patients with non-response to corticosteroids, results were similar to those of overall analyses, both for mortality and occurrence of infection. Conclusions Granulocyte colony-stimulating factor therapy may improve the prognosis of patients with severe AH. However, owing to the high heterogeneity observed in the overall analysis caused by conflicting results between the Asian and European studies, G-CSF cannot currently be recommended for AH, particularly in Europe. Whether these differences can be explained by ethnic differences or disparities in patient selection and disease severity remains unclear. Lay summary The main finding of this meta-analysis is that the use of granulocyte colony-stimulating factor (G-CSF) is associated with a mortality reduction of more than 70% at 3 months amongst patients with alcoholic hepatitis (AH) compared with controls who did not receive this therapy. However, owing to the high heterogeneity observed in the overall analysis caused by conflicting results between the Asian and European studies, G-CSF cannot currently be recommended for patients with AH, particularly in Europe. Whether these differences can be explained by ethnic differences or disparities in patient selection and disease severity remains unclear. This meta-analysis reports pooled data from 7 studies on the use of G-CSF in patients with alcoholic hepatitis. The favourable effect of G-CSF was only encountered in Asian not European studies. Additional data are needed to clarify the usefulness of G-CSF in severe alcoholic hepatitis, particularly in Europe.

Abstract
End-stage liver disease (ESLD) is life-threatening disease worldwide, and patients with ESLD should be referred to liver transplantation (LT). However, the use of LT is limited by the lacking liver source, high cost and organ rejection. Thus, other alternative options have been explored. Stem cell therapy may be a potential alternative for ESLD treatment. With the potential of self-renewal and differentiation, both hepatic and extrahepatic stem cells have attracted a lot of attention. Among them, multipotent stem cells are most widely studies owing to their characteristics. Multipotent stem cells mainly consist of two subpopulations: hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). Accumulating evidences have proved that either bone marrow (BM)-derived HSCs mobilized by granulocyte colony-stimulating factor or MSCs transplantation can improve the biochemical indicators of patients with ESLD. However, there are some challenges to be resolved before stem cells widely used in clinic, including the best stem cell source, the optimal route for stem cells transplantation, and the dose and frequency of stem cell injected. The purpose of this review is to discuss the potential of stem cell in liver diseases, particularly, the clinical progress and challenges of multipotent stem cells in the field of ESLD.

Abstract
Hematopoietic stem cells (HSCs) are regarded as one of essential cell sources for treating regenerative diseases. Among many stem cells, the feasibility of using adult-derived hematopoietic stem cells in therapeutic approaches is very diverse, and is unarguably regarded as an important cell source in stem cell biology. So far, many investigators are exploring HSCs and modified HSCs for use in clinical and basic science. In the present review, we briefly summarized HSCs and their application in pathophysiologic conditions, including non-hematopoietic tissue regeneration as well as blood disorders. HSCs and HSCs-derived progenitors are promising cell sources in regenerative medicine and their contributions can be properly applied to treat pathophysiologic conditions. Among many adult stem cells, HSCs are a powerful tool to treat patients with diseases such as hematologic malignancies and liver disease. Since HSCs can be differentiated into diverse progenitors including endothelial progenitors, they may be useful for constructing strategies for effective therapy.

Granulocyte Colony Stimulating Factor Ameliorates Hepatic Steatosis Associated with Improvement of Autophagy in Diabetic Rats. Can J Gastroenterol Hepatol 2020; 2020:2156829.

Abstract
BACKGROUND We previously reported that the granulocyte colony stimulating factor (G-CSF) ameliorated hepatic steatosis with the enhancement of β-oxidation-related gene expression. However, the mechanisms underlying this process remain unclear. This study aimed to determine whether the improvement of hepatic steatosis by G-CSF was associated with autophagy in a rat model of diabetes. METHODS Eight rats were fed a standard diet, and 16 rats were fed high-fat diet (HFD) for 5 weeks. All HFD-fed rats were then injected with streptozotocin (STZ). One week later, HFD rats injected with STZ were randomly treated with either G-CSF (200 μg/kg/day; diabetes mellitus (DM)/G-CSF) or saline (DM/saline) for 5 consecutive days. Four weeks later, serum biochemical and histology analyses were conducted. The expression of autophagy-associated proteins was determined by Western blotting. The mRNA expression of β-oxidation-related genes was determined by quantitative real-time polymerase chain reaction. HepG2 cells were cultured under high glucose (HG) conditions with G-CSF treatment, followed by Oil Red O staining for quantification of lipids. RESULTS Histological analysis showed lower lipid accumulation in the DM/G-CSF group than in the DM/saline-treated rats. Protein levels of LC3 and beclin-1 were higher, and those of p62 were lower in the DM/G-CSF rats than in the DM/saline-treated rats. The mRNA expression of β-oxidation-related genes was higher in DM/G-CSF rats than in the DM/saline-treated rats. Quantification of lipid levels in HepG2 cells cultured with HG and G-CSF treatment revealed no significant differences. CONCLUSIONS Our data suggested that G-CSF potentially improves hepatic steatosis and autophagy in the liver of diabetic rats.

Abstract
Liver cirrhosis progresses through multiple clinical stages which culminate in either death or liver transplantation. Availability of organs, timely listing and prompt receipt of donor-livers pose difficulties in improving transplant-listed and transplant outcomes. In this regard, regenerative therapies, particularly with granulocyte colony-stimulating factor (GCSF), has become a lucrative option for improving transplant-free survival. However, the literature is confusing with regards to patient selection and real outcomes. In this exhaustive review, we describe the basics of liver fibrosis and cirrhosis through novel insights from a therapeutic point of view, discuss preclinical studies on GCSF in advanced liver disease to improve on clinical utility, shed light on the pertinent literature of GCSF in advanced cirrhosis, and provide astute inputs on growth factor therapy in decompensated cirrhosis.

Abstract
Scarring is a result of the wound healing response and causes tissue dysfunction after injury. This process is readily evident in the skin, but also occurs internally across organ systems in the form of fibrosis. Stem cells are crucial to the innate tissue healing response and, as such, present a possible modality to therapeutically promote regenerative healing while minimizing scaring. In this review, the cellular basis of scaring and fibrosis is examined. Current stem cell therapies under exploration for skin wound healing and internal organ fibrosis are discussed. While most therapeutic approaches rely on the direct application of progenitor-type cells to injured tissue to promote healing, novel strategies to manipulate the scarring response are also presented. As our understanding of developmental and stem cell biology continues to increase, therapies to encourage regeneration of healthy functional tissue after damage secondary to injury or disease will continue to expand.

Abstract
Oil is an important nutrient in the human diet, and it is closely related to human life. For a long time, people's understanding of oil has been insufficient, resulting in some blind spots for oil intake. Excessive oil intake will increase blood triglyceride (TG), cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) concentrations, and the risk of chronic diseases such as cardiovascular and cerebrovascular diseases, obesity, fatty liver, and gastrointestinal tract diseases will be increased. Moreover, high-fat diets can also disrupt intestinal microbes and cause intestinal cancer. On the other hand, if oil intake is too low, the intake of essential fatty acids will be insufficient, and the absorption and utilization of fat-soluble vitamins will be reduced. The energy substances required for probiotics in the intestine will be reduced, and eventually the imbalance of human flora will lead to a variety of metabolic diseases. This article makes some simple discussions from the perspective of improper intake of edible oils, which will lead to dysbacteriosis and cause various diseases, with an aim to guide people to correctly choose dietary oils to improve the balance of intestinal flora.

Abstract
BACKGROUND & AIMS Peripheral blood stem cells (PBSCs) mobilized with colony-stimulating factor can promote liver regeneration and increase liver function in patients with liver diseases. However, the long-term effects of stem cell treatments on survival and risk of hepatocellular carcinoma (HCC) in patients with cirrhosis have not been determined. We investigated the long-term effects of autologous stem cell transplantation and risk of HCC in patients with cirrhosis. METHODS We performed a retrospective analysis of 2 cohorts of patients with decompensated cirrhosis who received transplantations of autologous PBSCs (n = 282) or standard medical treatment (SMT, n = 286) in China from January 1, 2006, through December 31, 2016. Patients were followed up until death or liver transplantation. Mortality data were obtained by case records and confirmed by telephone calls. Survival time was calculated and HCC was confirmed by computed tomography or ultrasound. We used propensity score matching to adjust the differences between the 2 groups. Survival and incidence of HCC were analyzed and Cox proportional hazard regression was used to determine the prognostic factors. RESULTS After propensity score matching, time of survival was significantly higher in the PBSC group than the SMT group (P = .001). The adjusted rate of 5-year survival was 71.2% in the PBSC group and 52.1% in the SMT group. The overall incidence of HCC did not differ significantly between the PBSC and SMT groups (21.1% vs 20.4%; P = .999). Significant improvement of liver functions was observed at 1 year, 2 years, 3 years, and 5 years after PBSC transplantation compared with the SMT group. CONCLUSIONS In a long-term analysis of patients with decompensated cirrhosis, autologous transplants of PBSCs significantly improved long-term survival compared with a control group. PBSC transplant did not appear to increase the risk of HCC.

[PMID: 30850965 DOI: 10.1007/s11033-019-04736-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Accepted: 02/28/2019] [Indexed: 12/17/2022]
Abstract
Natural killer (NK) cells have antifibrotic effects. We have evaluated the influence of rat bone marrow-mesenchymal stem cell (BM-MSC) treatment on liver histology, biochemical liver function tests, systemic immunoregulatory state and NK cell distribution in liver and peripheral blood in rat model of common bile duct (CBD) ligation and compared the results with the control group. Rats were divided into three groups: (1) CBD ligated (CBDL) rats received phosphate-buffered saline (CBDL + PBS group) or (2) MSC (CBDL + MSC group) and sham-operated rats received MSC (healthy + MSC group). We found significantly decreased fibrosis scores with BM-MSC treatment in CBDL rats compared to the control (CBDL + PBS) group while no fibrosis developed in sham operated (healthy + MSC) group. BM-MSC treatment has decreased the inflammation as reflected by the significantly decreased T cell proliferation and inflammatory cytokine concentrations from splenocyte culture and liver tissue itself compared to CBDL + PBS. NK cells both in parenchyme and portal areas decreased significantly in liver and blood in CBDL + PBS compared to healthy + MSC while they were found to be increased in CBDL + MSC compared to CBDL + PBS rats. In conclusion, BM-MSCs may suppress hepatic fibrosis accompanied by expanded intrahepatic NK cells in CBDL rats. Thus, our animal study shows that MSC treatment holds great promise for treatment of patients with end-stage liver diseases through a possible mechanism by adopting the NK cell population and new studies investigating the role of NK cells and clinical fibrosis are warranted.Trial registration number: Marmara University Animal Care and Use Committee approval code: 73.2013.mar.

Early cirrhosis and a preserved bone marrow niche favour regenerative response to growth factors in decompensated cirrhosis. Liver Int 2019; 39:115-126. [PMID: 29962032 DOI: 10.1111/liv.13923] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 06/12/2018] [Accepted: 06/28/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND Exogenous growth factor-mobilized bone marrow (BM) stem cells have shown a differential response in the management of decompensated cirrhosis (DC). This study was designed to evaluate potential clinical benefit of adding Erythropoietin (EPO) in granulocyte-colony stimulating factor (G-CSF)-mobilized stem cell therapy, possible mechanisms of regeneration and predictive factors of regenerative response. METHODS Sixty consecutive DC patients received either G-CSF with EPO (Group A; n = 30) or G-CSF and placebo (Group B; n = 30) for 2 months and were carefully followed up for 1 year. Baseline and post-treatment liver biopsy, BM biopsy and BM aspirate were analysed for fibro-inflammatory and regenerative response and BM hematopoietic reservoir. RESULTS Addition of EPO to G-CSF showed a significant improvement in Child-Pugh score (P = 0.03) and MELD score (P = 0.003) as compared to G-CSF alone, with reduction in mortality (16.6% vs 36.7%, P = 0.09). The combination arm also demonstrated a decreased incidence of acute kidney injury (P < 0.001), encephalopathy (P = 0.005) and refilling of ascites (P = 0.03). Compared to monotherapy, it increased CD163+ macrophages (P = 0.013), Ki67+ index (P < 0.001) with decrease in α-SMA levels (P < 0.001) in liver tissue. The response was better with grade 1 and 2 than with grade 3 ascites; Child B cirrhosis and MELD < 16. Non-responders had lower hematopoietic stem cells (HSCs) at baseline. On multivariate analysis, the liver disease severity (MELD < 16) and a relatively preserved BM (BM-HSCs > 0.4) predicted therapeutic response (AUROC = 0.82). CONCLUSIONS Early DC (MELD < 16) patients with mild-moderate ascites and those with a healthy cellular baseline BM respond better to growth factor therapy. Addition of EPO to G-CSF provides better regenerative response than G-CSF monotherapy.

Efficacy of granulocyte colony stimulating factor in patients with severe alcoholic hepatitis with partial or null response to steroid (GRACIAH trial): study protocol for a randomized controlled trial. Trials 2018; 19:696. [PMID: 30577864 PMCID: PMC6303849 DOI: 10.1186/s13063-018-3092-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Accepted: 11/30/2018] [Indexed: 12/20/2022] Open
Abstract
Background Alcoholic hepatitis (AH) has the most severe presentation among alcohol-related liver diseases. Corticosteroids are the most widely recommended treatment for severe AH. However, more innovative, refined treatment measures are required because of its high mortality despite corticosteroid treatment. This study aims to determine whether granulocyte colony stimulating factor (G-CSF) treatment increases short-term survival in patients with severe AH refractory to corticosteroid treatment. Methods/design Patients with severe AH whose Maddrey’s discriminant function (MDF) score is ≥ 32 and who will be treated with prednisolone (40 mg/day) for 1 week will be screened. Among them, 190 subjects with a partial response (PR) (Lille score 0.16–0.56), and 78 subjects with a null response (NR) (Lille score ≥ 0.56) will be enrolled. Subjects with PR will be randomized to steroid plus placebo or steroid plus 12 G-CSF injections (5 μg/kg/day for 5 days followed by every 3 days) at a ratio of 1:1. Subjects with a NR will be randomized to the placebo or G-CSF group (1:1). Study subjects in the PR group will be treated with prednisolone for 28 days followed by dose tapering for an additional 2 weeks. The primary endpoint is the 2-month survival rate in the NR group and the 6-month survival rate in the PR group. Child–Turcotte–Pugh, model for end-stage liver disease score, and the change in the proportion of peripheral circulating CD34-positive cells will be analyzed as risk factors for mortality. Preliminary safety data for the initial 10 study subjects enrolled in the PR study will be assessed to determine whether the PR study would be continued, according to the G-CSF-mobilized, peripheral-blood stem cell donor assessment protocol of the National Marrow Donor Program. Discussion We hypothesized that G-CSF would prolong short-term survival of patients with severe AH refractory to corticosteroid treatment. This is a proof-of-concept trial designed to assess the efficacy of Lille-score-guided G-CSF treatment. This trial is also designed to identify a special subgroup in whom G-CSF rescue treatment would improve liver function and prolong survival. Trial registration ClinicalTrials.gov, NCT02442180.

Therapeutic effect of hepatocyte growth factor-overexpressing bone marrow-derived mesenchymal stem cells on CCl 4-induced hepatocirrhosis. Cell Death Dis 2018; 9:1186. [PMID: 30538216 PMCID: PMC6290007 DOI: 10.1038/s41419-018-1239-9] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Revised: 11/13/2018] [Accepted: 11/23/2018] [Indexed: 12/24/2022]
Abstract
Hepatocirrhosis is one of the most severe complications of chronic hepatic disease in terms of medical intervention, and the available therapies are limited and not very successful. In this study, bone marrow-derived mesenchymal stem cells (BM-MSCs) from host rats were transduced with an adenoviral vector labelled with green fluorescent protein (EGFP) to overexpress hepatocyte growth factor (HGF). The therapeutic effect of these modified stem cells (HGF-BM-MSC group) transplanted intravenously into hepatocirrhosis model rats treated with CCl4 was evaluated using serological, biochemical and histological approaches. We compared the rats in the HGF-BM-MSC group with those in the other groups (rats treated with BM-MSCs, rats treated with HGF and untreated rats (Controls)) in detail. The localisation of EGFP-tagged BM-MSCs in the injured liver was evaluated using a microscope, and the cells co-expressed hepatocyte nuclear factor 4α, albumin and cytokeratin 18. After treatment for 4 weeks, the HGF-BM-MSC, BM-MSC and HGF groups exhibited increased protein and mRNA levels of hepatocyte nuclear factor 4α, albumin and cytokeratin 18, but decreased levels of aspartate aminotransferase, alanine aminotransferase and total bilirubin. These findings indicate that BM-MSC transplantation and HGF application have great potential for the treatment of hepatocirrhosis.

Abstract
Granulocyte colony stimulating factor (G-CSF) has been reported to ameliorate impaired liver function in patients with advanced liver diseases through mobilization and proliferation of hepatic progenitor cells (HPCs). However, the underlying mechanisms remain unknown. We previously showed that G-CSF treatment increased the number of bone marrow (BM)-derived cells migrating to the fibrotic liver following repeated carbon tetrachloride (CCl4 ) injections into mice. In this study, we identified opioid growth factor receptor-like 1 (OGFRL1) as a novel BM cell-derived accelerator of fibrotic liver regeneration in response to G-CSF treatment. Endogenous Ogfrl1 was highly expressed in the hematopoietic organs such as the BM and spleen, whereas the liver contained a relatively small amount of Ogfrl1 mRNA. Among the peripheral blood cells, monocytes were the major sources of OGFRL1. Endogenous Ogfrl1 expression in both the peripheral blood monocytes and the liver was decreased following repeated CCl4 injections. An intrasplenic injection of cells overexpressing OGFRL1 into CCl4 -treated fibrotic mice increased the number of HPC and stimulated proliferation of hepatic parenchymal cells after partial resection of the fibrotic liver. Furthermore, overexpression of OGFRL1 in cultured HPC accelerated their differentiation as estimated by increased expression of liver-specific genes such as hepatocyte nuclear factor 4α, cytochrome P450, and fatty acid binding protein 1, although it did not affect the colony forming ability of HPC. These results indicate a critical role of OGFRL1 in the mobilization and differentiation of HPC in the fibrotic liver, and administration of OGFRL1-expressing cells may serve as a potential regenerative therapy for advanced liver fibrosis.

Abstract
Objective This study is aimed at examining the impact of repeated intraportal autologous bone marrow transfusion (ABMT) in patients with decompensated liver cirrhosis after splenectomy. Methods A total of 25 patients with decompensated liver cirrhosis undergoing splenectomy were divided into ABMT and control groups. The portal vein was cannulated intraoperatively using Celsite Implantofix through the right gastroomental vein. Both groups were given a routine medical treatment. Then, 18 mL of autologous bone marrow was transfused through the port in the patients of the ABMT group 1 week, 1 month, and 3 months after laminectomy, while nothing was given to the control group. All patients were monitored for adverse events. Liver function tests, including serum albumin (ALB), alanine aminotransferase (ALT), total bilirubin (TB), prothrombin activity (PTA), cholinesterase (CHE), α-fetoprotein (AFP), and liver stiffness measurement (LSM), were conducted before surgery and 1, 3, and 6 months after surgery. Results Significant improvements in ALB, ALT, and CHE levels and decreased LSM were observed in the ABMT group compared with those in the control group (P < 0.05). TB and PTA improved in both groups but with no significant differences between the groups. No significant changes were observed in AFP in the control group, but it decreased in the ABMT group. No major adverse effects were noted during the follow-up period in the patients of either group. Conclusions Repeated intraportal ABMT was clinically safe, and liver function of patients significantly improved. Therefore, this therapy has the potential to treat patients with decompensated liver cirrhosis after splenectomy. This trial was registered with the identification number of ChiCTR-ONC-17012592.

Abstract
BACKGROUND & AIMS Patients with alcoholic hepatitis (AH) have high mortality, so new therapies are needed. Administration of granulocyte colony stimulating factor (G-CSF) increases survival times of patients with AH. It is not known whether addition of N-acetyl cysteine (NAC) to G-CSF could further increase survival time. We performed a randomized controlled pilot study to compare the efficacy of standard medical therapy with pentoxifylline to treatment with a combination of G-CSF and standard medical therapy as well as to the combination of NAC, G-CSF, and standard medical therapy in patients with severe AH. METHODS We performed an open-label, single-center study of 57 patients with severe AH admitted to a Liver Intensive Care unit in India from October 2014 through March 2017. Patients were randomly assigned to groups that received standard medical therapy (with pentoxifylline) plus G-CSF for 5 days (G-CSF group; n = 18), standard medical therapy plus G-CSF and intravenous NAC for 5 days (combination group; n = 19), or standard medical therapy alone (n = 20). Clinical data and blood samples were collected at baseline; on day 6; and 1, 2, and 3 months after the study began. CD34+ cells were measured in blood samples collected on days 0 and 6. The primary outcome was proportion of patients surviving for 90 days. Secondary outcomes were mobilization of CD34+ cells at day 6, as well as Child Turcotte Pugh, model for end-stage liver disease, and modified discriminant function scores until day 90. RESULTS Significantly higher proportions of patients in the G-CSF group (16/18) and the combination group (13/19) survived for 90 days than in the standard medical therapy group (6/20) (P = .0001 for G-CSF group and P = .037 and combination group). The GGSF and combination groups each had increased numbers of CD34+ cells from baseline until day 6, compared with the standard medical therapy group. The G-CSF group (but not the combination group) had significantly larger median reductions in modified discriminant function scores at study months 1 (reduction of 60.36%), 2 (reduction of 75.36%), and 3 (reduction of 88.73%) vs the standard medical therapy group (P = .02; P = .05; and P = .00, respectively). The G-CSF group had a significantly larger median reduction in model for end-stage liver disease score at 3 months (reduction of 55.77%; P = .01), but not in Child Turcotte Pugh score, compared with the standard medical therapy group. All groups had similar numbers of complications. CONCLUSION In a pilot randomized controlled trial, we found administration of G-CSF to improve liver function and increase survival times in patients with severe AH, compared with standard therapy. We found no evidence for benefit of adding NAC to G-CSF. These findings require confirmation in larger trials. ClincialTrials.gov, number: NCT02971306.

Abstract
Myeloid cells play a major role in the sensitization to liver injury, particularly in chronic inflammatory liver diseases with a biliary or hepatocellular origin, and the interplay between myeloid cells and the liver may explain the increased incidence of hepatic osteodystrophy. The myeloid cell-liver axis involves several mature myeloid cells as well as immature or progenitor cells with the complexity of the liver immune microenvironment aggravating the mist of cell differentiation. The unique positioning of the liver at the junction of the peripheral and portal circulation systems underlines the interaction of myeloid cells and hepatic cells and leads to immune tolerance breakdown. We herein discuss the scenarios of different chronic liver diseases closely modulated by myeloid cells and illustrate the numerous potential targets, the understanding of which will ultimately steer the development of solid immunotherapeutic regimens. Ultimately, we are convinced that an adequate modulation of the liver microenvironment to modify the functional and quantitative characteristics of myeloid cells will be a successful approach to treating chronic liver diseases of different etiologies.

Abstract
Background Bone marrow-derived mesenchymal stem cells (BMSCs) have blossomed into an effective approach with great potential for the treatment of liver fibrosis. The aim of this study was to investigate the underlying antifibrosis mechanisms by which the BMSC inhibit activated hepatic stellate cells (HSCs) in vivo and in vitro. Methods To study the effect of human bone marrow-derived mesenchymal stem cells (hBM-MSCs) on activated HSCs, we used HSCs and the coculture systems to evaluate the inhibition of activated HSCs from the aspects of the apoptosis of activated HSCs. In addition, activation of NADPH oxidase pathway and the changes in liver histopathology were tested by using the carbon tetrachloride- (CCl4-) induced liver fibrosis in mice. Results Introduction of hBM-MSCs significantly inhibited the proliferation of activated HSCs by inducing the apoptosis process of activated HSCs. The effect of hBM-MSCs reduced the signaling pathway of NADPH oxidase in activated HSCs. Besides, the signaling pathway of NADPH oxidase mediated hBM-MSC upregulation of the expression of the peroxisome proliferator-activated receptor γ and downregulation of the expression of α1(I) collagen and alpha-smooth muscle actin (α-SMA) in activated HSCs. Moreover, the hBM-MSC-induced decrease in the signaling pathway of NADPH oxidase was accompanied by the decrease of the activated HSC number and liver fibrosis in a mouse model of CCl4-induced liver fibrosis. Conclusion The hBM-MSCs act as a promising drug source against liver fibrosis development with respect to hepatopathy as a therapeutic target.

Abstract
BACKGROUND Results of small-scale studies have suggested that stem-cell therapy is safe and effective in patients with liver cirrhosis, but no adequately powered randomised controlled trials have been done. We assessed the safety and efficacy of granulocyte colony-stimulating factor (G-CSF) and haemopoietic stem-cell infusions in patients with liver cirrhosis. METHODS This multicentre, open-label, randomised, controlled phase 2 trial was done in three UK hospitals and recruited patients with compensated liver cirrhosis and MELD scores of 11·0-15·5. Patients were randomly assigned (1:1:1) to receive standard care (control), treatment with subcutaneous G-CSF (lenograstim) 15 μg/kg for 5 days, or treatment with G-CSF for 5 days followed by leukapheresis and intravenous infusion of three doses of CD133-positive haemopoietic stem cells (0·2 × 106 cells per kg per infusion). Randomisation was done by Cancer Research UK Clinical Trials Unit staff with a minimisation algorithm that stratified by trial site and cause of liver disease. The coprimary outcomes were improvement in severity of liver disease (change in MELD) at 3 months and the trend of change in MELD score over time. Analyses were done in the modified intention-to-treat population, which included all patients who received at least one day of treatment. Safety was assessed on the basis of the treatment received. This trial was registered at Current Controlled Trials on Nov 18, 2009; ISRCTN, number 91288089; and the European Clinical Trials Database, number 2009-010335-41. FINDINGS Between May 18, 2010, and Feb 26, 2015, 27 patients were randomly assigned to the standard care, 26 to the G-CSF group, and 28 to the G-CSF plus stem-cell infusion group. Median change in MELD from day 0 to 90 was -0·5 (IQR -1·5 to 1·1) in the standard care group, -0·5 (-1·7 to 0·5) in the G-CSF group, and -0·5 (-1·3 to 1·0) in the G-CSF plus stem-cell infusion group. We found no evidence of differences between the treatment groups and control group in the trends of MELD change over time (p=0·55 for the G-CSF group vs standard care and p=0·75 for the G-CSF plus stem-cell infusion group vs standard care). Serious adverse events were more frequent the in G-CSF and stem-cell infusion group (12 [43%] patients) than in the G-CSF (three [11%] patients) and standard care (three [12%] patients) groups. The most common serious adverse events were ascites (two patients in the G-CSF group and two patients in the G-CSF plus stem-cell infusion group, one of whom was admitted to hospital with ascites twice), sepsis (four patients in the G-CSF plus stem-cell infusion group), and encephalopathy (three patients in the G-CSF plus stem-cell infusion group, one of whom was admitted to hospital with encephalopathy twice). Three patients died, including one in the standard care group (variceal bleed) and two in the G-CSF and stem-cell infusion group (one myocardial infarction and one progressive liver disease). INTERPRETATION G-CSF with or without haemopoietic stem-cell infusion did not improve liver dysfunction or fibrosis and might be associated with increased frequency of adverse events compared with standard care.

Phase 1-2 pilot clinical trial in patients with decompensated liver cirrhosis treated with bone marrow-derived endothelial progenitor cells. Transl Res 2017; 188:80-91.e2. [PMID: 26972567 DOI: 10.1016/j.trsl.2016.02.009] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2015] [Revised: 02/12/2016] [Accepted: 02/17/2016] [Indexed: 01/13/2023]
Abstract
The aim of this nonrandomized, open label, phase 1 clinical trial was to evaluate the safety and the feasibility of the treatment with autologous bone marrow-derived endothelial progenitor cells (EPC) in decompensated liver cirrhosis. In addition, the changes in liver function and hepatic venous pressure gradient (HVPG) and their relation with the characteristics of the cellular product were analyzed. Twelve patients with Child-Pugh ≥8 liver cirrhosis underwent bone marrow harvest for ex vivo differentiation of EPC. The final product was administered through the hepatic artery in a single administration. Patients underwent clinical and radiologic follow-up for 12 months. The phenotype and the ability to produce cytokines and growth factors of the final cellular suspension were analyzed. Eleven patients were treated (feasibility 91%). No treatment-related severe adverse events were observed as consequence of any study procedure or treatment. Model for end-stage liver disease score improved significantly (P 0.042) in the first 90 days after cells administration and 5 of the 9 patients alive at 90 days showed a decreased of HVPG. There was a direct correlation between the expression of acetylated-low density lipoprotein and von Willebrand factor in the cellular product and the improvement in liver function and HVPG. The treatment with EPCs in patients with decompensated liver cirrhosis is safe and feasible and might have therapeutic potential. Patients receiving a higher amount of functionally active EPC showed an improvement of liver function and portal hypertension suggesting that the potential usefulness of these cells for the treatment of liver cirrhosis deserves further evaluation.

Abstract
BACKGROUND AIMS Growing evidence supports the therapeutic potential of bone marrow (BM)-derived stem/progenitor cells for end-stage liver disease (ESLD). We recently demonstrated that CD133+ stem/progenitor cell (SPC) reinfusion in patients with ESLD is feasible and safe and improve, albeit transiently, liver function. However, the mechanism(s) through which BM-derived SPCs may improve liver function are not fully elucidated. METHODS Here, we characterized the circulating SPCs compartment of patients with ESLD undergoing CD133+ cell therapy. Next, we set up an in vitro model mimicking SPCs/liver microenvironment interaction by culturing granulocyte colony-stimulating factor (G-CSF)-mobilized CD133+and LX-2 hepatic stellate cells. RESULTS We found that patients with ESLD show normal basal levels of circulating hematopoietic and endothelial progenitors with impaired clonogenic ability. After G-CSF treatment, patients with ESLD were capable to mobilize significant numbers of functional multipotent SPCs, and interestingly, this was associated with increased levels of selected cytokines potentially facilitating SPC function. Co-culture experiments showed, at the molecular and functional levels, the bi-directional cross-talk between CD133+ SPCs and human hepatic stellate cells LX-2. Human hepatic stellate cells LX-2 showed reduced activation and fibrotic potential. In turn, hepatic stellate cells enhanced the proliferation and survival of CD133+ SPCs as well as their endothelial and hematopoietic function while promoting an anti-inflammatory profile. DISCUSSION We demonstrated that the interaction between CD133+ SPCs from patients with ESLD and hepatic stellate cells induces significant functional changes in both cellular types that may be instrumental for the improvement of liver function in cirrhotic patients undergoing cell therapy.

Abstract
BACKGROUND Liver transplantation is the only curative option for patients with decompensated cirrhosis; however, many patients die while awaiting transplantation. Granulocyte colony-stimulating factor (GCSF) has shown promising results in improving outcomes in patients with advanced liver disease. We evaluated the efficacy of GCSF in patients with decompensated cirrhosis in an open-labeled randomized-controlled trial. METHODS Consecutive patients with decompensated cirrhosis were randomized to receive either GCSF 300 μg twice daily for 5 days plus standard medical therapy (SMT) (GCSF+SMT group) or SMT alone (SMT alone group). Outcomes were assessed at 6 months from randomization. RESULTS A total of 126 patients [median age: 53 (range: 31-76) years, 85% men] received GCSF+SMT and 127 patients received SMT alone. Baseline characteristics were similar in both the groups. The 5-day GCSF therapy did not lead to any significant adverse effects. At 6 months, in the GCSF+SMT group, 17 patients had died and nine were lost to follow-up, whereas in the SMT-alone group, 30 patients had died and 11 were lost to follow-up. By intention-to-treat analysis, cumulative survival was significantly higher in the GCSF+SMT group (79 vs. 68%; P=0.025). Also, significantly more patients (66%) showed improvement or stability in the Child-Turcotte-Pugh score at 6 months in the GCSF+SMT group compared with the SMT-alone group (51%, P=0.021). CONCLUSION GCSF therapy improves survival and clinical outcome in patients with decompensated cirrhosis. It may be useful in patients awaiting transplantation to prevent worsening during the waiting period. Further studies are needed to explore whether repeated periodic GCSF courses can further increase the survival and decrease the need for liver transplantation.Clinical trial registered at https://clinicaltrials.gov vide NCT02642003.

Abstract
BACKGROUND/AIMS Liver transplantation offers the only definite cure for cirrhosis but lacking donors is problem. Stem cell therapy is attractive in this setting. In this study, we aimed to explore the safety and efficacy of ultrasound-guided percutaneous portal transplantation of peripheral blood monocyte cell (PBMC) in cirrhotic patients. METHODS A total of nine decompensated cirrhotic patients were randomized into three groups: group 1 (n = 3) was control group, group 2 (n = 3) received granulocyte-colony stimulating factor (G-CSF) mobilization for 3 days, and group 3 (n = 3) received G-CSF mobilized PBMCs by leukapheresis and PBMC transplantation through ultrasound-guided percutaneous portal vein puncture. Liver function and clinical features were evaluated. RESULTS At baseline, the Child-Turcotte-Pugh and the model for end-stage liver disease scores were comparable in study groups. Compared with group 1, there was a tendency to improve liver function in group 3 at 6 months after treatment. Treatment was tolerable and no complications were encountered related to the G-CSF mobilization or percutaneous portal administration of PBMCs. Imaging studies showed patent portal veins at the end of the study period. CONCLUSIONS Autologous PBMC transplantation through ultrasound-guided percutaneous portal vein puncture could be considered as a safe alternative treatment for decompensated cirrhotic patients.

Abstract
Liver transplantation has been accepted as a useful therapeutic approach for patients with end-stage liver disease. However, the mismatch between the great demand for liver transplants and the number of available donor organs underscores the urgent need for alternative therapeutic strategies for patients with acute and chronic liver failure. The rapidly growing knowledge on stem cell biology has opened new avenues toward stem cell-based therapy for liver disease. As stem cells have capacity for high proliferation and multipotent differentiation, the characteristics of stem cells fit the cell therapy. Several types of cells have been investigated as possible sources of liver regeneration: mesenchymal stem cells, hematopoietic stem cells, liver progenitor cells, induced pluripotent stem cells, and bone marrow mononuclear cells. In vitro and in vivo experiments revealed that these cells have great potential as candidates of stem cell therapy. We reviewed the reports on clinical trials of cell therapy for liver disease that have been recently undertaken using mesenchymal stem cells, hematopoietic stem cells, bone marrow mononuclear cells, and liver progenitor cells. These reports have heterogeneity of description of trial design, types of infused cells, patient population, and efficacy of therapies. We addressed these reports from these viewpoints and clarified their significance. We hope that this review article will provide a perspective on the available approaches based on stem cell-based therapy for liver disease.

Abstract
AIM: To evaluate the efficacy of umbilical cord-derived mesenchymal stem cells (UC-MSCs) transplantation in the treatment of liver fibrosis.
METHODS: Cultured human UC-MSCs were isolated and transfused into rats with liver fibrosis induced by dimethylnitrosamine (DMN). The effects of UC-MSCs transfusion on liver fibrosis were then evaluated by histopathology; serum interleukin (IL)-4 and IL-10 levels were also measured. Furthermore, Kupffer cells (KCs) in fibrotic livers were isolated and cultured to analyze their phenotype. Moreover, UC-MSCs were co-cultured with KCs in vitro to assess the effects of UC-MSCs on KCs’ phenotype, and IL-4 and IL-10 levels were measured in cell culture supernatants. Finally, UC-MSCs and KCs were cultured in the presence of IL-4 antibodies to block the effects of this cytokine, followed by phenotypical analysis of KCs.
RESULTS: UC-MSCs transfused into rats were recruited by the injured liver and alleviated liver fibrosis, increasing serum IL-4 and IL-10 levels. Interestingly, UC-MSCs promoted mobilization of KCs not only in fibrotic livers, but also in vitro. Co-culture of UC-MSCs with KCs resulted in increased production of IL-4 and IL-10. The addition of IL-4 antibodies into the co-culture system resulted in decreased KC mobilization.
CONCLUSION: UC-MSCs could increase IL-4 and promote mobilization of KCs both in vitro and in vivo, subsequently alleviating the liver fibrosis induced by DMN.

Abstract
BACKGROUND AND AIMS It remains controversial whether granulocyte colony-stimulating factor (G-CSF) prolongs survival in liver failure (LF) patients. This meta-analysis was performed to evaluate the effect of G-CSF on patients with LF. METHODS PubMed, EMBASE, and Web of Science databases were searched to identify English language randomized controlled trials comparing G-CSF with control therapy published before14 February 2015. A meta-analysis was performed to examine changes in liver function and patient survival. The association was tested using odds ratio (OR) or risk ratio (RR) with 95% confidence intervals (CI). RESULTS Five randomized controlled trials were eligible for the meta-analysis. Significant amelioration of prothrombin time and total bilirubin in LF patients was attributed to G-CSF therapy (OR, -0.064; 95% CI,-0.481 to 0.353; p< 0.001; and OR, -0.803; 95% CI, -1.177 to -0.430; p = 0.000, respectively). Treatment with G-CSF resulted in improved Model for End-Stage Liver Disease and Child-Turcotte-Pugh scores (OR, -1.741; 95% CI, -2.234 to -1.250; p = 0.000; and OR, -0.830, 95% CI, -1.194 to -0.465; p = 0.000, respectively). A lower incidence of sepsis was found in patients treated with G-CSF (RR, 0.367; 95% CI, 0.158 to 0.854; p = 0.020). G-CSF therapy significantly increased survival rate in LF patients (RR, 2.25; 95% CI, 1.517 to 3.338; p = 0.000). CONCLUSIONS The results of this meta-analysis indicate that G-CSF treatment in patients with LF significantly improved liver function, reduced the incidence of sepsis, and prolonged short-term survival.

Clinical effectiveness of cell therapies in patients with chronic liver disease and acute-on-chronic liver failure: a systematic review protocol. Syst Rev 2016; 5:100. [PMID: 27301957 PMCID: PMC4908794 DOI: 10.1186/s13643-016-0277-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2016] [Accepted: 05/31/2016] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Chronic liver disease (CLD) is a major health burden worldwide. Liver cirrhosis, a form of CLD is the fifth most common cause of death in the UK. Acute-on-chronic liver failure (ACLF) is the result of an acute insult superimposed on patients with liver cirrhosis as a result of precipitating events such as infection or bleeding. ACLF has a high associated mortality as a result of multi-organ failure. The only effective treatment for CLD is liver transplantation, but the treatment is limited by shortage of donor organs. As a result, alternative treatments such as cell therapies have been studied in patients with liver diseases. This study will systematically review the evidence on clinical effectiveness of cell therapies in patients. METHODS All types of study design that investigate the effectiveness of cell therapies (haematopoietic, mesenchymal and unsorted cell types) of autologous or allogeneic origin and/or the use of granulocyte colony-stimulating factor in patients with CLD including ACLF will be included (except case reports). Both autologous and allogenic cell types will be included. The primary outcomes of interest are survival, model for end-stage liver disease score, quality of life and adverse events. Secondary outcomes include liver function tests, Child-Pugh score and events of liver decompensation. A literature search will be conducted in the following databases: MEDLINE, MEDLINE in Process, EMBASE and Cochrane Library (CENTRAL, CDSR, DARE, HTA databases). Trial registers will be searched for ongoing trials, as will conference proceedings. Reference lists of relevant articles and systematic reviews will be screened. Randomised controlled trial (RCT) evidence is likely to be scant; therefore, controlled trials and concurrently controlled observational studies will be primarily analysed and uncontrolled observational studies will be analysed where primary outcomes are not reported in the control studies or where uncontrolled studies have longer follow-up. Initial screening of studies will be carried by one reviewer with a proportion checked by another reviewer. Full-text selection will be performed by two reviewers independently against the pre-defined selection criteria. The data collection and the risk of bias assessment will be completed by one reviewer and counter checked by another reviewer for all selected studies.

Abstract
Background and Objectives Use of pluripotent stem cells is an ideal solution for liver insufficiencies. This work aims is to evaluate the safety and feasibility of autologous stem cells transplantation (SCT) in Egyptian patients of liver cirrhosis on top of hepatitis C virus (HCV). Subjects and Results 20 patients with HCV induced liver cirrhosis were divided into 2 groups. Group I: included 10 patients with liver cirrhosis Child score ≥9, for whom autologous stem cell transplantation was done using granulocyte colony stimulating factor (G-CSF) for stem cells mobilization. Separation and collection of the peripheral blood stem cells was done by leukapheresis. G-CSF mobilized peripheral blood mononuclear cells (G-CSF PB-MNCs) were counted by flow cytometry. Stem cell injection into the hepatic artery was done. Group II: included 10 patients with HCV induced liver cirrhosis as a control group. Follow up and comparison between both groups were done over a follow up period of 6 months. The procedure was well tolerated. Mobilization was successful and the total number of G-CSF PB-MNCs in the harvests ranged from 25×106 to 191×106. There was improvement in the quality of life, serum albumin, total bilirubin, liver enzymes and the Child-Pugh score of group I over the first two-three months after the procedure. Conclusion SCT in HCV induced liver cirrhosis is a safe procedure. It can improve the quality of life and hepatic functions transiently with no effect on the life expectancy or the fate of the liver cirrhosis.

Abstract
BACKGROUND Bone marrow stem/progenitor cells seem to be effective in liver regeneration after tissue injury. AIM To evaluate the feasibility and safety of the mobilization and reinfusion of CD133+ stem/progenitor cells in patients with end-stage liver disease. METHODS Autologous CD133+ stem/progenitor cells, mobilized with granulocyte-colony stimulating factor, were collected by leukapheresis and reinfused at increasing doses through the hepatic artery starting from 5×10(4)/kg up to 1×10(6)/kg. RESULTS 16 subjects with Model for End-stage Liver Disease (MELD) score between 17 and 25 were enrolled, 14 mobilized an adequate number of CD133+ stem/progenitor cells and 12 were reinfused. No severe adverse events related to the procedure were reported. MELD score significantly worsened during mobilization in Child Turcotte Pugh-C patients. A significant improvement of liver function was observed 2 months after reinfusion (MELD 19.5 vs. 16; P=0.045). Overall, 5 patients underwent liver transplantation within 12 months from reinfusion and 2 died because of progressive liver failure. CONCLUSIONS CD133+ stem/progenitor cells reinfusion in patients with end-stage liver disease is feasible and safe. A worsening of liver function was observed during mobilization in Child Turcotte Pugh-C patients. The temporary improvement of MELD score after reinfusion suggests that stem cells therapy may be a "bridge to transplant" approach for these patients.

Abstract
Cirrhosis occurs as a result of various chronic liver injuries, which may be caused by viral infections, alcohol abuse and the administration of drugs and chemicals. Recently, bone marrow cells (BMCs), hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) have been used for developing treatments for cirrhosis. Clinical trials have investigated the therapeutic potential of BMCs, HSCs and MSCs for the treatment of cirrhosis based on their potential to differentiate into hepatocytes. Although the therapeutic mechanisms of BMC, HSC and MSC treatments are still not fully characterized, the evidence thus far has indicated that the potential therapeutic mechanisms of MSCs are clearer than those of BMCs or HSCs with respect to liver regenerative medicine. MSCs suppress inflammatory responses, reduce hepatocyte apoptosis, increase hepatocyte regeneration, reverse liver fibrosis and enhance liver functionality. This paper summarizes the clinical studies that have used BMCs, HSCs and MSCs in patients with liver failure or cirrhosis. We also present the potential therapeutic mechanisms of BMCs, HSCs and MSCs for the improvement of liver function.

Abstract
Hematopoietic stem cells (HSC) represent the prototype stem cell within the body. Since their discovery, HSC have been the focus of intensive research, and have proven invaluable clinically to restore hematopoiesis following inadvertent radiation exposure and following radio/chemotherapy to eliminate hematologic tumors. While they were originally discovered in the bone marrow, HSC can also be isolated from umbilical cord blood and can be "mobilized" peripheral blood, making them readily available in relatively large quantities. While their ability to repopulate the entire hematopoietic system would already guarantee HSC a valuable place in regenerative medicine, the finding that hematopoietic chimerism can induce immunological tolerance to solid organs and correct autoimmune diseases has dramatically broadened their clinical utility. The demonstration that these cells, through a variety of mechanisms, can also promote repair/regeneration of non-hematopoietic tissues as diverse as liver, heart, and brain has further increased their clinical value. The goal of this review is to provide the reader with a brief glimpse into the remarkable potential HSC possess, and to highlight their tremendous value as therapeutics in regenerative medicine.

Abstract
BACKGROUND/AIMS Therapies involving bone-marrow-derived mesenchymal stem cells (BM-MSCs) have considerable potential in the management of hepatic disease. BM-MSCs have been investigated in regenerative medicine due to their ability to secrete various growth factors and cytokines that regress hepatic fibrosis and enhance hepatocyte functionality. The aim of this study was to determine the antifibrosis effect of BM-MSCs on activated hepatic stellate cells (HSCs) and the mechanism underlying how BM-MSCs modulate the function of activated HSCs. METHODS We used HSCs in both direct and indirect co-culture systems with BM-MSCs to evaluate the antifibrosis effect of BM-MSCs. The cell viability and apoptosis were evaluated by a direct co-culture system of activated HSCs with BM-MSCs. The activations of both HSCs alone and HSCs with BM-MSCs in the direct co-culture system were observed by immunocytochemistry for alpha-smooth muscle actin (α-SMA). The levels of growth factors and cytokines were evaluated by an indirect co-culture system of activated HSCs with BM-MSCs. RESULTS The BM-MSCs in the direct co-culture system significantly decreased the production of α-SMA and the viability of activated HSCs, whereas they induced the apoptosis of activated HSCs. The BM-MSCs in the indirect co-culture system decreased the production of transforming growth factor-β1 and interleukin (IL)-6, whereas they increased the production of hepatocyte growth factor and IL-10. These results confirmed that the juxtacrine and paracrine effects of BM-MSCs can inhibit the proliferative, fibrogenic function of activated HSCs and have the potential to reverse the fibrotic process by inhibiting the production of α-SMA and inducing the apoptosis of HSCs. CONCLUSIONS These results have demonstrated that BM-MSCs may exert an antifibrosis effect by modulating the function of activated HSCs.

Abstract
Over the past five decades, liver cirrhosis has become an increasingly prevalent disease and one that will often require considerable medical intervention. However, current treatment options have demonstrated severe problems that have prompted research to provide a suitable alternative. These treatments are scarcely available, very expensive and present at a huge cost to the patient's quality of life. The introduction of stem cell therapy into liver disease has been heralded as the future of personalized medicine and may be the alternative that the healthcare system desperately seeks. To truly determine the scientific basis surrounding this excitement, a literature search was carried out in January 2013 to determine all the data that was present in this topic area. All articles also underwent full cross-referencing to ensure no data was missed. 11 clinical trials were found to meet this criteria and trials were included in both English and non-English languages. The sporadic nature of the data across the trials, with various methods and stem cell types, made comparisons difficult. The basic trends from the data were positive and the majority deemed the use of stem cells safe and feasible in patients presenting with cirrhotic liver disease. However, there is a clear requirement for more research, not only to determine the most efficacious technique and stem cell type but also to further understand stem cells to enhance progress. There may also be a requirement for a framework that future stem cell trials can be based on, which would allow future data to be comparative and allow valid conclusions to be drawn which may propel this therapy into standard clinical practice.

Abstract
Background Currently available treatment options for decompensated hepatitis B-induced liver cirrhosis are limited and largely ineffective. Recently, stem cell transplantation has emerged as a promising treatment for cirrhosis. The aim of this study was to determine whether autologous peripheral blood stem cell transplantation can improve liver functional reserve in patients with hepatitis B-induced cirrhosis. Material/Methods In this study, 51 patients with hepatitis B-induced liver cirrhosis were assigned to the treatment group (n=23) or the control group (n=28). The treatment group underwent autologous peripheral blood stem cell transplantation in addition to comprehensive medical treatment, and the control group received comprehensive medical treatment alone. Liver functional reserve was monitored for 48 weeks after autologous peripheral blood stem cell transplantation. Results After transplantation, most patients showed improvements in symptoms such as fatigue, anorexia, and abdominal distension. The retention rate of indocyanine green at 15 minutes, a common indicator of liver functional reserve, declined from 41.99±4.68 at baseline to 37.79±3.75 by 48 weeks after transplantation, showing significant improvement. Conclusions Autologous peripheral blood stem cell transplantation can improve several markers of liver health and liver functional reserve and is a promising prospect for clinical application.

Abstract
The clinical significance of enhancing endogenous circulating haematopoietic stem cells is becoming increasingly recognized, and the augmentation of circulating stem cells using granulocyte-colony stimulating factor (G-CSF) has led to promising preclinical and clinical results for several liver fibrotic conditions. However, this approach is largely limited by cost and the infeasibility of maintaining long-term administration. Preclinical studies have reported that StemEnhance, a mild haematopoietic stem cell mobilizer, promotes cardiac muscle regeneration and remedies the manifestation of diabetes. However, the effectiveness of StemEnhance in ameliorating liver cirrhosis has not been studied. This study is the first to evaluate the beneficial effect of StemEnhance administration in a thioacetamide-induced mouse model of liver fibrosis. StemEnhance augmented the number of peripheral CD34-positive cells, reduced hepatic fibrosis, improved histopathological changes, and induced endogenous liver proliferation. In addition, VEGF expression was up-regulated, while TNF-α expression was down-regulated in thioacetamide-induced fibrotic livers after StemEnhance intake. These data suggest that StemEnhance may be useful as a potential therapeutic candidate for liver fibrosis by inducing reparative effects via mobilization of haematopoietic stem cells.

Abstract
The aim of the present study was to compare the effects of bone marrow-derived mesenchymal stem cells (BMSCs) transplanted via the portal vein or tail vein on liver injury in rats with liver cirrhosis. BMSCs were isolated from rat bone marrow and labeled with green fluorescent protein (GFP). Then, the labeled BMSCs were injected into rats with liver injury via the portal vein or tail vein. Two weeks after transplantation, three rats in each group were sacrificed to test the distribution of GFP in the liver and the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and albumin. Six weeks later, the remaining rats were sacrificed, and serum ALT, AST, albumin, hyaluronic acid (HA), laminin (LN) and procollagen type III (PC-III) levels were measured. The expression of albumin in the liver was analyzed by immunohistochemistry. Two weeks after BMSC transplantation, GFP-positive cells were detected in the livers of rats with BMSCs transplanted via the portal vein and tail vein. Compared with pre-transplantation levels, the ALT levels of the groups with BMSC transplantation via the portal vein and tail vein were significantly decreased after two and six weeks of BMSC transplantation (P<0.05), whereas the AST and albumin levels were not significantly different at two weeks after BMSC transplantation in the two groups (all P>0.05). However, the AST and albumin levels were significantly reduced at six weeks after BMSC transplantation (all P<0.05). At six weeks after BMSC transplantation, the serum HA, LN and PC-III levels in rats transplanted with BMSCs via the portal vein or tail vein had decreased significantly (all P<0.05), as compared with the levels prior to BMSC transplantation. BMSCs transplanted via the portal vein and tail vein achieved similar improvements in liver function in rats with liver cirrhosis, which suggests that peripheral venous administration is a convenient and effective route for BMSC transplantation.

Abstract
Anthrax lethal toxin (LT), one of the primary virulence factors of Bacillus anthracis, causes anthrax-like symptoms and death in animals. Experiments have indicated that levels of erythrocytopenia and hypoxic stress are associated with disease severity after administering LT. In this study, the granulocyte colony-stimulating factor (G-CSF) was used as a therapeutic agent to ameliorate anthrax-LT- and spore-induced mortality in C57BL/6J mice. We demonstrated that G-CSF promoted the mobilization of mature erythrocytes to peripheral blood, resulting in a significantly faster recovery from erythrocytopenia. In addition, combined treatment using G-CSF and erythropoietin tended to ameliorate B. anthracis-spore-elicited mortality in mice. Although specific treatments against LT-mediated pathogenesis remain elusive, these results may be useful in developing feasible strategies to treat anthrax.

Abstract
BACKGROUND AND AIM Preclinical studies in rodent models of chronic liver fibrosis have shown that transplantation of peripheral blood (PB) CD34(+) cells leads to hepatic regeneration and a reduction of liver fibrosis by suppressing hepatic stellate cell activity and increasing matrix metalloproteinase activity. The aim of this study was to examine the safety and clinical efficacy of intrahepatic transplantation of autologous granulocyte colony-stimulating factor (G-CSF)-mobilized PB-CD34(+) cells in patients with decompensated liver cirrhosis. METHODS PB-CD34(+) cells were isolated from G-CSF-mobilized apheresis products. Ten patients were treated with G-CSF-mobilized PB-CD34(+) cells (treatment group) and seven patients were treated with standard medical therapy. For mobilization, patients in the treatment group received subcutaneous injections of 10 μg G-CSF/kg/day for 5 days. The cells were then injected at three different doses (5 × 10(5) , 1 × 10(6) and 2 × 10(6) cells/kg) through the hepatic artery. Thereafter, all patients were followed up for 24 months. RESULTS G-CSF treatment and leukapheresis were well tolerated, and no serious adverse events were observed. Patients in the treatment group had a significant but transient splenomegaly. After 24 weeks, serum albumin was significantly increased in patients who had received middle or high doses of CD34(+) cells compared with baseline. Doppler ultrasound showed a significant increase in hepatic blood flow velocity and blood flow volume after CD34(+) cell therapy. The hepatic vein pressure gradient decreased in two patients who received high-dose CD34(+) cells at week 16. CONCLUSIONS CD34(+) cell therapy is feasible, safe and effective in slowing the decline of hepatic reserve function.

Abstract
There are increasing reports of using bone marrow-derived stem cells to treat advanced liver disease. We consider several critical issues that underlie this approach. For example, are there multipotent stem cell populations in human adult bone marrow? Can they develop into liver cells or supporting cell types? What are stromal stem/progenitor cells, and can they promote tissue repair without replacing hepatocytes? Does reversal of end-stage liver disease require new hepatocytes, a new liver microenvironment, both, neither or something else? Although many of these questions are unanswered, we consider the conceptual and experimental bases underlying these issues and critically analyze results of clinical trials of stem cell therapy of end-stage liver disease.
