Evolution of Electrospinning in Liver Tissue Engineering. Biomimetics (Basel) 2022; 7:biomimetics7040149. [PMID: 36278706 PMCID: PMC9589992 DOI: 10.3390/biomimetics7040149] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Revised: 09/09/2022] [Accepted: 09/15/2022] [Indexed: 11/17/2022] Open
Abstract
The major goal of liver tissue engineering is to reproduce the phenotype and functions of liver cells, especially primary hepatocytes ex vivo. Several strategies have been explored in the recent past for culturing the liver cells in the most apt environment using biological scaffolds supporting hepatocyte growth and differentiation. Nanofibrous scaffolds have been widely used in the field of tissue engineering for their increased surface-to-volume ratio and increased porosity, and their close resemblance with the native tissue extracellular matrix (ECM) environment. Electrospinning is one of the most preferred techniques to produce nanofiber scaffolds. In the current review, we have discussed the various technical aspects of electrospinning that have been employed for scaffold development for different types of liver cells. We have highlighted the use of synthetic and natural electrospun polymers along with liver ECM in the fabrication of these scaffolds. We have also described novel strategies that include modifications, such as galactosylation, matrix protein incorporation, etc., in the electrospun scaffolds that have evolved to support the long-term growth and viability of the primary hepatocytes.

Combination of ULK1 and LC3B improve prognosis assessment of hepatocellular carcinoma. Biomed Pharmacother 2017; 97:195-202. [PMID: 29091866 DOI: 10.1016/j.biopha.2017.10.025] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2017] [Revised: 09/30/2017] [Accepted: 10/03/2017] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Autophagy involves in both prevention and promotion in cancer, and its role probably changed during tumor development. Defined the dynamic function of autophagy in cancer may advance precision diagnostics, treatment, and guide drug design. Autophagy related protein ULK1 is key regulator of autophagy, and its role in hepatocellular carcinoma (HCC) was still unclear. This study aims to investigate ULK1's capacity along with other autophagic markers in predicting prognosis of HCC and explore position of these biomarkers in dynamic function of autophagy during HCC progression. METHODS The expression of ULK1 and other autophagic marker (LC3B) were test by Tissue microarray-based immunohistochemistry in 156 operable HCC patients. Survival analysis and correlation analysis were used to analysis influence of ULK1 and combined biomarker on clinical characteristics and prognosis. RESULTS The expression level of ULK1 was not related to all clinicopathological features, however, high expression of the ULK1 as well as LC3B overexpression suggested large tumor size (P=0.035), high levels of serum AFP (P=0.049), more frequency of node metastasis (P=0.015), later TNM stage (P=0.009). Survival analysis showed that ULK1 expression were negatively correlated with PFS rather than OS in HCC patients (P=0.021), while LC3B were suggested to be negatively related with patients' PFS, However, Simultaneous high expression of ULK1 and LC3B had a poorer 5-year overall survival (OS) rate (P=0.002) and shorter 5-year progression free survival (PFS)(P=0.003), Further multivariate analysis revealed that the two combined biomarkers were independent factors to predict the prognosis of OS and PFS in all patients, while ULK1 alone or LC3B alone were only an independent predict factor for OS or PFS respectively. CONCLUSION ULK1 were demonstrated to be an important prognostic factor for HCC patient, and it combined LC3B would improve prognosis assessment of the patients. Combined autophagic biomarkers would better represent dynamic stage of autophagy and It might provide a potential therapeutic way that how to interfere autophagy in HCC.

Prevention of hepatitis C virus infection by adoptive allogeneic immunotherapy using suicide gene-modified lymphocytes: an in vitro proof-of-concept. Gene Ther 2014; 22:172-80.

Abstract
Hepatitis C virus (HCV)-induced, end-stage liver disease is a major indication for liver transplantation, but systematic graft reinfection accelerates liver disease recurrence. Transplantation recipients may be ineligible for direct-acting antivirals, owing to toxicity, resistance or advanced liver disease. Adoptive immunotherapy with liver graft-derived, ex vivo-activated lymphocytes was previously shown to prevent HCV-induced graft reinfections. Alternatively, the applicability and therapeutic efficacy of adoptive immunotherapy may be enhanced by 'ready for use' suicide gene-modified lymphocytes from healthy blood donors; moreover, conditional, prodrug-induced cell suicide may prevent potential side effects. Here, we demonstrate that allogeneic suicide gene-modified lymphocytes (SGMLs) could potently, dose- and time-dependently, inhibit viral replication. The effect occurs at effector:target cell ratios that exhibits no concomitant cytotoxicity toward virus-infected target cells. The effect, mediated mostly by CD56+ lymphocytes, is interleukin-2-dependent, IFN-γ-mediated and, importantly, resistant to calcineurin inhibitors. Thus, post-transplant immunosuppression may not interfere with this adoptive cell immunotherapy approach. Furthermore, these cells are indeed amenable to conditional cell suicide; in particular, the inducible caspase 9 suicide gene is superior to the herpes simplex virus thymidine kinase suicide gene. Our data provide in vitro proof-of-concept that allogeneic, third-party, SGMLs may prevent HCV-induced liver graft reinfection.

Abstract
Liver transplantation is currently the most efficacious treatment for end-stage liver diseases. However, one main problem with liver transplantation is the limited number of donor organs that are available. Therefore, liver tissue engineering based on cell transplantation that combines materials to mimic the liver is under investigation with the goal of restoring normal liver functions. Tissue engineering aims to mimic the interactions among cells with a scaffold. Particular materials or a matrix serve as a scaffold and provide a three-dimensional environment for cell proliferation and interaction. Moreover, the scaffold plays a role in regulating cell maturation and function via these interactions. In cultures of hepatic lineage cells, regulation of cell proliferation and specific function using biocompatible synthetic, biodegradable bioderived matrices, protein-coated materials, surface-modified nanofibers, and decellularized biomatrix has been demonstrated. Furthermore, beneficial effects of addition of growth factor cocktails to a flow bioreactor or coculture system on cell viability and function have been observed. In addition, a system for growing stem cells, liver progenitor cells, and primary hepatocytes for transplantation into animal models was developed, which produces hepatic lineage cells that are functional and that show long-term proliferation following transplantation. The major limitation of cells proliferated with matrix-based transplantation systems is the high initial cell loss and dysfunction, which may be due to the absence of blood flow and the changes in nutrients. Thus, the development of vascular-like scaffold structures, the formation of functional bile ducts, and the maintenance of complex metabolic functions remain as major problems in hepatic tissue engineering and will need to be addressed to enable further advances toward clinical applications.

Abstract
BACKGROUND A higher incidence of autoimmune disorders may predispose First Nations (FN) individuals to higher rates and more severe episodes of rejection, graft loss and mortality following liver transplantation for advanced liver disease. METHODS A retrospective review of patient outcomes in a single centre providing long-term follow-up care for FN and non-FN patients transplanted for advanced liver disease was conducted. RESULTS A total of 20 FN and 129 non-FN charts were available for review. FN subjects were younger at transplantation (mean [± SD] age 32.4±4.1 years versus 46.3±1.4 years; P=0.00005), less often male (35% versus 58%; P=0.05), more commonly transplanted for autoimmune hepatitis (30% versus 4.7%; P=0.006), less often from urban residences (25% versus 74%; P=0.0001) and less compliant with medical care (20% versus 80%; P=0.007). After a mean follow-up period of 11.0±1.5 years and 8.4±0.5 years in FN and non-FN subjects, respectively, the incidence and severity of rejection, graft and patient survival were similar between cohorts. CONCLUSION Although demographic profiles, nature of the underlying disease and compliance differed, the rates and severity of rejection, graft and patient survival were similar in FN and non-FN patients who underwent liver transplantation for advanced liver disease.

Abstract
INTRODUCTION Right lobe donor hepatectomy (RLDH) is a potential source of liver allografts given the ongoing shortage of deceased donor organs available. Since there is no live donor registry in the United States, a population-based, unsolicited state-wide analysis has yet to be reported. METHODS The New York (NY) State Inpatient Database was used to query 1,524 elective liver lobectomies performed from 2001 to 2006. RLDH were identified in this cohort (n = 195; 13%). Most common indications for elective right lobe hepatectomy (ERH) were metastatic colon cancer (50%) and hepatocellular carcinoma (HCC) (34%). Primary outcomes were mortality, perioperative resources and major postoperative complications. RESULTS After a dramatic drop in 2002, there was a slow increase in RLDH from 2003 to 2006 in New York. Donors were younger (median age 36 vs. 60 years, P < 0.0001) and healthier (75% with no comorbidities vs. 18%, P < 0.0001) than patients undergoing ERH for other causes. Median length of hospital stay was 7 days in both groups. Donors were less likely to require blood transfusion (22.6 vs. 62.8%, P < 0.0001) and received less blood (mean 0.10 units vs. 2.4 units). Major post-operative complications based on the Clavien classification occurred in only 2.6% of donor cases compared to 13.8% in non-donors (P < 0.0001). There was one RLDH in-hospital mortality (0.5%) in New York compared to 4.3% after ERH (P = 0.003). CONCLUSIONS This study represents one of the first unsolicited regional analyses of donor morbidity and resource utilization for RLDH and further emphasizes the need and utility of a live donor registry.

Abstract
To analyze the outcome of solid organ transplantation (SOT) in patients who had undergone allogeneic hematopoietic stem cell transplantation (HSCT), a questionnaire survey was carried out within 107 European Group of Blood and Marrow Transplantation centers. This study covered HSCT between 1984 and 2007 in Europe. Forty-five SOT in 40 patients were reported. Fifteen liver, 15 renal, 13 lung, 1 heart and 1 skin transplantations were performed in 28 centers. Overall survival (OS) of patients after SOT was 78% at 5 years (95% confidence interval [CI], 64% to 92%). OS at 5 years was 100% for renal, 71% (95% CI, 46% to 96%) for liver and 63% (95% CI, 23% to 100%) for lung transplant recipients. The 2-year-incidence of SOT failure was 20% (95% CI, 4% to 36%) in patients with graft-versus-host disease (GvHD) and 7% (95% CI, 0% to 21%) in patients without GvHD before SOT. The relapse incidence for underlying malignant diseases was 4% at 5 years (95% CI, 0% to 12%). In summary, this study shows that selected patients receiving SOT after HSCT have a remarkably good overall and organ survival. These data indicate that SOT should be considered in selected patients with single organ failure after HSCT.
