HPF Modulates the Differentiation of BMSCs into HLCs and Promotes the Recovery of Acute Liver Injury in Mice. Int J Mol Sci 2023; 24:ijms24065686. [PMID: 36982757 PMCID: PMC10058346 DOI: 10.3390/ijms24065686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 03/13/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023] Open
Abstract
Bone marrow-derived mesenchymal stem cells (BMSCs) can differentiate into hepatocyte-like cells (HLCs) to alleviate acute liver injury (ALI). Herpetfluorenone (HPF), as an active ingredient in the dried, mature seeds Herpetospermum caudigerum Wall, used in Tibetan medicine, has been proven to effectively alleviate ALI. Therefore, the purpose of this study was to determine whether HPF can promote the differentiation of BMSCs into HLCs and promote ALI recovery. Mouse BMSCs were isolated, and the BMSCs’ differentiation into HLCs was induced by HPF and hepatocyte growth factor (HGF). Under the induction of HPF and HGF, the expression of hepatocellular specific markers and the accumulation of glycogen and lipids in the BMSCs increased, indicating that BMSCs successfully differentiated into HLCs. Then, the ALI mouse model was established, using carbon tetrachloride, followed by an intravenous injection of BMSCs. Then, only HPF was injected intraperitoneally, in order to verify the effect of HPF in vivo. In vivo imaging was used to detect the homing ability of HPF–BMSCs, and it was detected that HPF–BMSCs significantly increased the levels of serum AST, ALT and ALP in the liver of ALI mice, and alleviated liver cell necrosis, oxidative stress and liver pathology. In conclusion, HPF can promote the differentiation of BMSCs into HLCs and promote the recovery of ALI in mice.

Abstract
Background: Cobia (Rachycentron canadum) is a species of fish with high commercial potential particularly due to fast growth rates. The evidence of sexual size dimorphism favoring females indicate potential benefits in having a monosex culture. However, the involvement of genetic factors responsible for sexual development and gonadal maintenance that produces phenotypic sex in cobia is largely unknown. Methods: In the present study, we performed transcriptome sequencing of cobia to identify sex-biased significantly differentially expressed genes (DEGs) in testes and ovaries. The reliability of the gonad transcriptome data was validated by qPCR analysis of eight selected significantly differential expressed sex-related candidate genes. Results: This comparative gonad transcriptomic analysis revealed that 7,120 and 4,628 DEGs are up-regulated in testes or ovaries, respectively. Further functional annotation analyses identified 76 important candidate genes involved in sex determination cascades or sex differentiation, including 42 known testis-biased DEGs (dmrt1, amh and sox9 etc.), and 34 known ovary-biased DEGs (foxl2, sox3 and cyp19a etc.). Moreover, eleven significantly enriched pathways functionally related to sex determination and sex differentiation were identified, including Wnt signaling pathway, oocyte meiosis, the TGF-beta signaling pathway and MAPK signaling pathway. Conclusion: This work represents the first comparative gonad transcriptome study in cobia. The putative sex-associated DEGs and pathways provide an important molecular basis for further investigation of cobia's sex determination, gonadal development as well as potential control breeding of monosex female populations for a possible aquaculture setting.

Abstract
The current treatment for liver failure is restricted to surgical liver transplantation, which is technically complicated, limited by the shortage of available organs and presents major risks to the patient. Bone marrow mesenchymal stem cells (BMSCs) represent promising sources of hepatocyte-like cells for cell transplantation treatment. However, a safe and efficient induction method for their differentiation remains to be defined. Here we further optimized an effective technique by combining high-dose treatment with hepatocyte growth factor (HGF) and ultrasound stimulation. The optimized ultrasound parameter (1.0 W/cm2 intensity, 1 MHz frequency, 20% duty cycle, 100 Hz pulse repetition frequency, 60-s irradiation duration, triple times in three days) combined with different HGF doses (10, 20 and 50 ng/ml) was used to treat BMSCs. The results showed that the specific hepatic markers, including α-fetoprotein (αFP/AFP), cytokeratin 18 (CK18), albumin (ALB) and glycogen, were increased in a dose-dependent manner. Their concentration was then further increased when ultrasound irradiation was administered (P < 0.05), as indicated by PCR, Western blot and immunofluorescence staining as well as a glycogen synthesis test. Furthermore, analysis of the hepatocyte-derived chemokines showed elevated stromal cell-derived factor 1alpha (SDF-1α) and C-X-C chemokine receptor type 4 (CXCR4) after HGF treatment. Again, concentrations of those chemokines were further increased by ultrasound radiation (P < 0.05). The observed increased effect was sustained for 21 days. To summarize, we further defined the optimal combination of HGF and ultrasound treatment to increase the differentiation and chemotaxis of BMSCs in a safe, sustained and efficient manner. These findings provide a new perspective for stem cell orientation in the field of tissue engineering.

Abstract
OBJECTIVE To investigate the effect of galectin-3 in inducing the differentiation of rat bone marrow mesenchymal stem cells (BMSCs) into hepatocyte- like cells and explore the involvement of the signaling pathways in the induced cell differentiation. METHODS The third passage of cultured rat femoral BMSCs were treated with 0.5 μg/mL galectin-3, 20 ng/mL hepatocyte growth factor (HGF) or both to induce their differentiation, with untreated rat BMSCs and hepatocytes as controls. At 7, 14, 21 and 28 days of induction, the cells were examined for morphological changes followed by glycogen staining, quantitative real-time PCR and Western blotting. Gene microarray technique was used to examine the mRNA expression profile of the BMSCs induced with galectin-3. The BMSCs were also induced with galectin-3 in combination with XMU-MP-1, a Hippo signaling pathway inhibitor, after which Western blotting was performed to detect the expressions of YAP, P-YAP, ALB, AFP and CK-18 in the cells. RESULTS The cells isolated from the femoral bone marrow of SD rats showed a consistent surface marker phenotype with the BMSCs. Induction with galectin-3, HGF, or both all resulted in gradual morphological changes of the BMSCs into hepatocyte-like cells, and the cells with a combined induction for 28 days showed the highest morphological similarity with hepatocytes. The cells induced with galectin-3, HGF, or their combination for 28 days all showed increased positivity rate of glycogen staining, which was the highest in the cells with combined induction (P < 0.05) without significant difference between the cells induced with galectin-3 and HGF alone (P > 0.05). Induction with galectin-3 and HGF alone both increased the expressions of AFP, ALB and CK-18 mRNAs in the cells, and their expression levels were similar between the cells at 28 days (P > 0.05). Galectin-3 and HGF did not show an interactive effect on the mRNA expressions of AFP (F=0.236, P=0.640) or ALB (F=50.639, P=0.000), but had a synergistic effect on CK-18 mRNA expression (F=50.639, P=0.000). The protein expressions of AFP, ALB and CK18 were also increased in the induced cells but not detected in the cells without induction. Gene microarray results revealed 27 up-regulated genes and 62 down-regulated genes in galectin-3-induced BMSCs involving TGF-β, PI3K-Akt and Hippo signal pathways. Induction with galectin-3 and galectin-3+XMU-MP-1 increased YAP expression in the cells, and galectin-3+XMU-MP-1 was more efficient to induce the differentiation of the BMSCs. CONCLUSIONS Galectin-3 can induce the differentiation of rat BMSCs into hepatocyte-like cells, and the combination with HGF increases the efficiency of induced differentiation of the cells. TGF-β, PI3K-Akt and Hippo pathways are involved in the induced differentiation of the BMSCs, and inhibiting Hippo pathway can improve the induction efficiency.

Abstract
Liver regeneration/repair is a compensatory regrowth following acute liver failure, and bone marrow-derived mesenchyme stem cell (BMSC) transplantation is an effective therapy that promotes liver regeneration/repair. Wnt1 inducible signaling pathway protein 2 (Wisp2) is highly expressed in BMSCs, however, its function remains unclear. In this work, we used clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein -9 nuclease (CRISPR/Cas9) genome editing technology to knockdown Wisp2 in BMSCs, and these modified cells were then transplanted into rats which were induced by the 2-AAF/PH. By linking the expression of Cas9 to green fluorescent protein (GFP), we tracked BMSCs in the rats. Disruption of Wisp2 inhibited the homing of BMSCs to injured liver and aggravated liver damage as indicated by remarkably high levels of ALT and AST. Moreover, the key factor in BMSC transplantation, C-X-C chemokine receptor type 4 (Cxcr4), was down-regulated in the Wisp2 depleted BMSCs and had a lower expression in the livers of the corresponding rats. By tracing the GFP marker, more BMSCs were observed to differentiate into CD31 positive endothelial cells in the functional Wisp2 cells but less in the Wisp2 gene disrupted cells. In summary, Wisp2 promotes the homing of BMSCs through Cxcr4 related signaling during liver repair in rats.

Abstract
Mesenchymal stromal/stem cells (MSC) are promising candidates for cellular therapy of different diseases in humans and in animals. Following the guidelines of the International Society for Cell Therapy, human MSC may be identified by expression of a specific panel of cell surface markers (CD105+, CD73+, CD90+, CD34-, CD14-, or CD11b-, CD79- or CD19-, HLA-DR-). In addition, multiple differentiation potential into at least the osteogenic, adipogenic, and chondrogenic lineage is a main criterion for MSC definition. Human MSC and MSC of a variety of mammals isolated from different tissues meet these criteria. In addition to the abovementioned, they express many more cell surface markers. Yet, these are not uniquely expressed by MSC. The gross phenotypic appearance like marker expression and differentiation potential is similar albeit not identical for MSC from different tissues and species. Similarly, MSC may feature different biological characteristics depending on the tissue source and the isolation and culture procedures. Their versatile biological qualities comprising immunomodulatory, anti-inflammatory, and proregenerative capacities rely largely on the migratory and secretory capabilities of MSC. They are attracted to sites of tissue lesion and secrete factors to promote self-repair of the injured tissue. This is a big perspective for clinical MSC applications in both veterinary and human medicine. Phase I/II clinical trials have been initiated to assess safety and feasibility of MSC therapies in acute and chronic disease settings. Yet, since the mode of MSC action in a specific disease environment is still unknown at large, it is mandatory to unravel the response of MSC from a given source onto a specific disease environment in suitable animal models prior to clinical applications. © 2017 International Society for Advancement of Cytometry.

Abstract
Intra-amniotic injection of lipopolysaccharide (LPS) induces pulmonary hypertension in newborn rats. This study was designed to test whether human mesenchymal stem cells (MSCs) reduce pulmonary hypertension and alleviate cardiac hypertrophy in prenatal LPS-treated rats. Pregnant Sprague-Dawley rats were injected intraperitoneally with LPS (0.5 mg/kg per day) or untreated on gestational days 20 and 21. Human MSCs (3×10(5) cells and 1×10(6) cells) in 0.03 mL of normal saline (NS) were transplanted intratracheally on postnatal day 5. Four study groups were considered: normal, LPS+NS, LPS+MSCs (3×10(5) cells), and LPS+MSCs (1×10(6) cells). On postnatal day 14, lung and heart tissues were collected for measuring the arterial medial wall thickness (MWT) and β-myosin heavy chain (β-MHC) level as markers of pulmonary hypertension and cardiac hypertrophy, respectively. The LPS+NS group exhibited a significantly higher right ventricle (RV)/[left ventricle (LV)+ interventricular septum (IVS)] thickness ratio and MWT, a greater cardiomyocyte width, a greater number of cardiomyocyte nuclei per squared millimeter, and higher β-MHC expression than those observed in the normal group. Human MSC transplantation (3×10(5) cells and 1×10(6) cells) in LPS-treated rats reduced MWT and the RV/(LV+IVS) thickness ratio to normal levels. This improvement in right ventricular hypertrophy was accompanied by a decrease in toll-like receptor 4 (TLR4), nuclear factor-κB, and tumor necrosis factor-α expression in the heart. Intratracheal human MSCs transplantation can attenuate pulmonary hypertension and right ventricular hypertrophy in prenatal LPS-treated rats; this attenuation may be associated with suppression of TLR4 expression via paracrine pathways.

Abstract
Supplemental digital content is available in the text. Background Ischemia-reperfusion injury (IRI) is commonly encountered after liver surgery. This study evaluated the hepatoprotective effects of topically applied adipose-derived mesenchymal stromal cells (ADMSCs) on hepatic IRI in a rat model. Methods ADMSCs from transgenic green fluorescent protein Sprague-Dawley rats were topically applied to the liver surface of Sprague-Dawley rats after hepatic IRI and fixed in position by fibrin glue (group A, n = 24). An equivalent amount of ADMSCs were administered through the portal (group B, n = 24) or tail vein (group C, n = 24). In the control group (group D, n = 20), no treatment was given to the IRI liver. Results All the rats in group A and group D survived. Within 2 days after hepatic IRI, only 50% of rats survived in group B, and ADMSCs were detected in thromboemboli within large vessels. 62.5% of the rats died in group C because most of the ADMSCs were trapped in the lungs. ADMSCs migrated across the liver capsule and homed to the injured liver parenchyma 3 days after topical application in group A. The homed ADMSCs expressed hepatocyte nuclear factor-4α and hepatocyte nuclear factor-1. Compared with group D, the rate of hepatic regeneration in group A was enhanced with less inflammation, smaller necrotic areas, and improved liver function. Proinflammatory cytokines IL-6, IL-21, and CD70 were significantly downregulated in group A by 6.3-, 2.7-, and 12.7-fold, respectively (P < 0.05). The neurogenic locus NOTCH homolog protein pathway was activated in the topical ADMSCs. Conclusions Topically applied adipose-derived mesenchymal stromal cells demonstrated hepatoprotective effects on hepatic IRI in an animal model.

Abstract
Stem cell transplantation has been investigated to rescue experimental liver failure and is promising to offer an alternative therapy to liver transplantation for liver diseases treatment. Several clinical studies in this field have been carried out, but the therapeutic benefit of this treatment is still controversial. A major obstacle to developing stem cell therapies in clinic is being able to visualize the cells in vivo. Imaging modalities allow optimization of delivery, detecting cell survival and functionality by in vivo monitoring these transplanted graft cells. Moreover, theranostic imaging is a brand new field that utilizes nanometer-scale materials to glean diagnostic insight for simultaneous treatment, which is very promising to improve stem cell-based therapy for treatment of liver diseases. The aim of this review was to summarize the various imaging tools that have been explored with advanced molecular imaging probes. We also outline some recent progress of preclinical and clinical studies of liver stem cells transplantation. Finally, we discuss theranostic imaging for stem cells transplantation for liver dysfunction and future opportunities afforded by theranostic imaging.

Abstract
Yiguanjian is administered in traditional Chinese medicine for liver diseases and has been demonstrated to reduce liver fibrosis. This study investigated the effect of Yiguanjian drug-containing serum (YGJ) with Stromal Cell-Derived Factor 1 (SDF-1) and Hepatocyte Growth Factor (HGF) on the differentiation of murine bone-marrow-derived mesenchymal cells (BM-MSCs) into hepatocytes in vitro. Adherent MSCs were isolated from murine bone marrow. Differentiation was induced by 20 ng/mL HGF, 50 ng/mL SDF-1, and 20% Yiguanjian drug-containing serum for 7 to 28 days, and mature hepatocytes' marker albumin (ALB) and cholangiocytes' marker cytokeratin-18 (CK-18) were assessed by immunocytochemistry and western blot. BM-MSCs exhibited homogeneous spindle shape growth after subculture and stained positive for CD90 and negative for CD34. After induction with HGF + normal serum or YGJ for 14 days, HGF + SDF-1 + normal serum for 7 days, or HGF + SDF-1 + YGJ for 5 days, MSCs' morphology changed gradually and begun to resemble hepatocyte-like cells. Cultures supplemented with HGF + SDF-1 + YGJ contained significantly higher proportions of ALB and CK-18 positive cells than cultures supplemented with HGF + SDF-1 + normal serum at day 7. These observations corroborated the results of western blot. In conclusion, Yiguanjian drug-containing serum could facilitate the differentiation of murine BM-MSCs into hepatocytes in vitro and has a synergistic effect with SDF-1 and HGF.

Abstract
Cirrhosis is the end-stage liver fibrosis, whereby normal liver architecture is disrupted by fibrotic bands, parenchymal nodules and vascular distortion. Portal hypertension and hepatocyte dysfunction are the end results and give rise to major systemic complications and premature death. Mesenchymal stem cells (MSC) have the capacity of self-renew and to give rise to cells of various lineages, so MSC can be isolated from bone marrow (BM) and induced to differentiate into hepatocyte-like cells. MSC were induced to differentiate into hepatocyte-like cells by hepatotic growth factor (HGF) and fibroblast growth factor-4 (FGF-4). Differentiated cells were examined for the expression of hepatocyte-specific markers and hepatocyte functions. MSC were isolated. Flow cytometry analysis showed that they expressed the MSC-specific markers, reverse transcriptase-polymerase chain reaction (RT-PCR) demonstrated that MSC expressed the hepatocyte-specific marker cytokeratin 18 (CK-18) following hepatocyte induction. This study demonstrates that BM-derived-MSC can differentiate into functional hepatocyte-like cells following the induction of HGF and FGF-4. MSC can serve as a favorable cell source for tissue engineering in the treatment of liver disease.

Abstract
End‐stage liver disease can be the termination of acute or chronic liver diseases, with manifestations of liver failure; transplantation is currently an effective treatment for these. However, transplantation is severely limited due to the serious lack of donors, expense, graft rejection and requirement of long‐term immunosuppression. Mesenchymal stem cells (MSCs) have attracted considerable attention as therapeutic tools as they can be obtained with relative ease and expanded in culture, along with features of self‐renewal and multidirectional differentiation. Many scientific groups have sought to use MSCs differentiating into functional hepatocytes to be used in cell transplantation with liver tissue engineering to repair diseased organs. In most of the literature, hepatocyte differentiation refers to use of various additional growth factors and cytokines, such as hepatocyte growth factor (HGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), oncostatin M (OSM) and more, and most are involved in signalling pathway regulation and cell–cell/cell–matrix interactions. Signalling pathways have been shown to play critical roles in embryonic development, tumourigenesis, tumour progression, apoptosis and cell‐fate determination. However, mechanisms of MSCs differentiating into hepatocytes, particularly signalling pathways involved, have not as yet been completely illustrated. In this review, we have focused on progress of signalling pathways associated with mesenchymal stem cells differentiating into hepatocytes along with the stepwise differentiation procedure.

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
Stem cells have opened a new avenue to treat liver fibrosis. We investigated in vitro and in vivo the effect of cytokine (HGF and FGF4) pretreated MSCs in reduction of CCl4 liver injury. Mouse MSCs were pretreated with cytokines to improve their ability to reduce CCl4 injury. In vitro we gave CCl4 injury to mouse hepatocytes and cocultured it with untreated and cytokines pretreated MSCs. For in vivo study we labeled MSCs with PKH-26 and transplanted them into CCl4 injured mice by direct injection into liver. In vitro data showed that cytokines pretreated MSCs significantly reduce LDH level and apoptotic markers in CCl4 injured hepatocytes cocultured model. Furthermore the cytokines pretreated MSCs also improved cell viability and enhanced hepatic and antiapoptotic markers in injured hepatocytes cocultured model as compared to untreated MSCs. In vivo data in cytokines pretreated group demonstrated greater homing of MSCs in liver, restored glycogen storage, and significant reduction in collagen, alkaline phosphatase, and bilirubin levels. TUNEL assay and real time PCR also supported our hypothesis. Therefore, cytokines pretreated MSCs were shown to have a better therapeutic potential on reduction of liver injury. These results demonstrated the potential utility of this novel idea of cytokines pretreated MSCs for the treatment of liver fibrosis.

Abstract
BACKGROUND AND OBJECTIVES Cell therapy provides an effective strategy for the treatment of an impaired liver. Human umbilical cord blood progenitor cells have the potential to differentiate into hepatocytes. Progenitor cells transplanted into the spleen could migrate directly into the liver through portal circulation. To track migration of human umbilical cord blood progenitor cells in cirrhotic rat liver after intrasplenic transplantation and to prove the possibility similar behavior of human umbilical cord blood nucleated cells in humans. METHODS AND RESULTS Umbilical cord blood samples from full-term deliveries will be collected after obtaining an informed consent from the mother. The collection procedure will be conducted after completion of delivery and will not interfere with the normal obstetric procedures. Adult male Sprague Dawley rats were subjected to liver cirrhosis by intraperitoneal injection of thioacetamide. Cirrhotic rats were treated with human umbilical cord blood nucleated cells by intra-splenic transplantation. Migration of intrasplenic transplanted human umbilical cord blood cells to the liver was successfully documented with Immunohistochemistry. The liver and spleen from recipient animals were removed. Histopathological and immunohistochemical analysis were performed 20 weeks after intrasplenic injection of the cells. Intrasplenically injected cells migrate to the liver of recipient animals. CONCLUSIONS Human cord blood nucleated cells have the potential to differentiate into hepatocytes and substantially improve the histology and function of the cirrhotic liver in rats. Relocation into liver after intrasplenic transplantation could be detected by immunohistochemistry. Transdifferentiated cells could be efficiently stained with antihuman hepatocytes.

Abstract
Cellular therapy for end-stage liver failures using human mesenchymal stem cells (hMSCs)-derived hepatocytes is a potential alternative to liver transplantation. Hepatic trans-differentiation of hMSCs is routinely accomplished by induction with commercially available recombinant growth factors, which is of limited clinical applications. In the present study, we have evaluated the potential of sera from cardiac-failure-associated congestive/ischemic liver patients for hepatic trans-differentiation of hMSCs. Results from such experiments were confirmed through morphological changes and expression of hepatocyte-specific markers at molecular and cellular level. Furthermore, the process of mesenchymal-to-epithelial transition during hepatic trans-differentiation of hMSCs was confirmed by elevated expression of E-Cadherin and down-regulation of Snail. The functionality of hMSCs-derived hepatocytes was validated by various liver function tests such as albumin synthesis, urea release, glycogen accumulation and presence of a drug inducible cytochrome P450 system. Based on these findings, we conclude that sera from congestive/ischemic liver during cardiac failure support a liver specific microenvironment for effective hepatic trans-differentiation of hMSCs in vitro.

Abstract
Mesenchymal stem cells (MSC) isolated from bone marrow and differentiated into hepatocyte-like cells have increasingly gained attention for clinical cell therapy of liver diseases because of their high regenerative capacity. They are available from bone marrow aspirates of the os coxae after puncture of the crista iliaca or from bone marrow "surgical waste" gained from amputations or knee and hip operations. Thus, the aim of the study was to demonstrate whether these pBM-MSC (porcine bone marrow-derived mesenchymal stem cells) displayed mesenchymal features and hepatocyte differentiation potential. MSC were isolated either from crista iliaca punctures or after sampling and collagenase digestion of bone marrow from the os femoris. Mesenchymal features were assessed by flow cytometry for specific surface antigens and their ability to differentiate into at least 3 lineages. Functional properties, such as urea or glycogen synthesis and cytochrome P450 activity, as well as the cell morphology were examined during hepatocyte differentiation. pBM-MSC from both sources lacked the hematopoietic markers CD14 and CD45 but expressed the typical mesenchymal markers CD44, CD29, CD90, and CD105. Both cell types could differentiate into adipocyte, osteocyte, and hepatocyte lineages. After hepatocyte differentiation, CD105 expression decreased significantly and cells changed morphology from fibroblastoid into polygonal, displaying significantly increased glycogen storage, urea synthesis, and cytochrome activity. pBM-MSC from various sources were identical in respect to their mesenchymal features and their hepatocyte differentiation potential. Hence, long bones might be a particularly useful resource to isolate bone marrow mesenchymal stem cells for transplantation.

Abstract
STUDY BACKGROUND Extended liver resection is the only curative treatment option of liver cancer. Yet, the residual liver may not accomplish the high metabolic and regenerative capacity needed, which frequently leads to acute liver failure. Because of their anti-inflammatory and -apoptotic as well as pro-proliferative features, mesenchymal stem cells differentiated into hepatocyte-like cells might provide functional and regenerative compensation. Clinical translation of basic research requires pre-clinical approval in large animals. Therefore, we characterized porcine mesenchymal stem cells (MSC) from adipose tissue and bone marrow and their hepatocyte differentiation potential for future assessment of functional liver support after surgical intervention in the pig model. METHODS Mesenchymal surface antigens and multi-lineage differentiation potential of porcine MSC isolated by collagenase digestion either from bone marrow or adipose tissue (subcutaneous/visceral) were assessed by flow cytometry. Morphology and functional properties (urea-, glycogen synthesis and cytochrome P450 activity) were determined during culture under differentiation conditions and compared with primary porcine hepatocytes. RESULTS MSC from porcine adipose tissue and from bone marrow express the typical mesenchymal markers CD44, CD29, CD90 and CD105 but not haematopoietic markers. MSC from both sources displayed differentiation into the osteogenic as well as adipogenic lineage. After hepatocyte differentiation, expression of CD105 decreased significantly and cells adopted the typical polygonal morphology of hepatocytes. Glycogen storage was comparable in adipose tissue- and bone marrow-derived cells. Urea synthesis was about 35% lower in visceral than in subcutaneous adipose tissue-derived MSC. Cytochrome P450 activity increased significantly during differentiation and was twice as high in hepatocyte-like cells generated from bone marrow as from adipose tissue. CONCLUSION The hepatocyte differentiation of porcine adipose tissue-derived MSC was shown for the first time yielding hepatocyte-like cells with specific functions similar in bone marrow and subcutaneous adipose tissue-derived MSC. That makes them good pre-clinical candidates for supportive approaches after liver resection in the pig.

Abstract
Hemophilia is an X-linked bleeding disorder, and patients with hemophilia are deficient in a biologically active coagulation factor. This study was designed to combine the efficiency of lentiviral vector transduction techniques with murine adipose tissue-derived stem/stromal cells (mADSCs) as a new method to produce secreted human coagulation factor IX (hFIX) and to treat hemophilia B. mADSCs were transduced with simian immunodeficiency virus (SIV)-hFIX lentiviral vector at multiplicities of infection (MOIs) from 1 to 60, and the most effective dose was at an MOI of 10, as determined by hFIX production. hFIX protein secretion persisted over the 28-day experimental period. Cell sheets composed of lentiviral vector-transduced mADSCs were engineered to further enhance the usefulness of these cells for future therapeutic applications in transplantation modalities. These experiments demonstrated that genetically transduced ADSCs may become a valuable cell source for establishing cell-based gene therapies for plasma protein deficiencies, such as hemophilia.

Abstract
PURPOSE OF REVIEW Liver transplantation is the ultimate therapeutic option for the treatment of end-stage liver diseases, which, however, is restricted by the shortage of donor organs. Instead hepatocyte transplantation seemed to be a way out, but again marginal donor livers for the isolation of primary human hepatocytes are scarce. The hepatocyte differentiation capacity of mesenchymal stem cells might open a new cell resource to generate hepatocyte-like cells for therapeutical use. RECENT FINDINGS Apart from their potency of hepatocyte differentiation mesenchymal stem cells display pleiotropic biological features including modulation of immunogenicity, anti-inflammatory and anti-apoptotic as well as pro-proliferative impact at the site of tissue or organ lesions. They are mobilized from the bone marrow and migrate to the liver along chemoattractive gradients thus contributing to the humoral and cellular response in tissue repair. The cause of different liver diseases is varying depending on, for example, viral, toxic, nutritional, neoplastic challenges. As known from animal studies mesenchymal stem cells seem to have a beneficial impact on liver regeneration and tissue repair under a variety of liver disease conditions. SUMMARY Their versatile biological features render mesenchymal stem cells an alternate cell resource for the treatment of liver diseases. It is important to know the mechanisms of integration of transplanted cells into the recipient tissue and to understand the communication between donor cells and the host tissue on the molecular level in order to support efficacy of cell transplantation and thus optimize the therapeutical outcome.

Abstract
Adipose tissue-derived mesenchymal stem cells (AT-MSCs) are an attractive alternative for clinical application due to their minimally invasive accessibility and availability in the body. However, the hepatic differentiation efficiency of AT-MSCs is insufficient for therapeutic application and the role of extrahepatic stem cells in liver regeneration remains poorly understood. This study was designed to investigate the effects of serum from rats subjected to 70% partial hepatectomy (PH) on the differentiation ability of rat AT-MSCs in vitro, and to explore the potential role of AT-MSCs in vivo following PH injury. Results showed that AT-MSCs treated with serum collected from rats 24 h after 70% PH differen-tiated into hepatocyte-like cells, resembled hepatocyte-like cells with round or polygonal shape, expressed α-fetoprotein, secreted albumin, synthesized urea and acquired cytochrome P450 type 3A4 enzyme activity, and upregulated the expression of interleukin (IL)-6 and hepatocyte growth factor (HGF) transiently in vitro, although the hepatic differentiation efficiency was extremely low. AT-MSC transplantation after 70% PH ameliorated liver injury and promoted liver regeneration, but did not increase the serum levels of IL-6 and HGF in vivo. This result suggests that the therapeutic effect of AT-MSCs in vivo after 24 h of 70% PH does not increase IL-6 and HGF expression.

Abstract
Mesenchymal stem cells represent an alternate cell source to substitute for primary hepatocytes in hepatocyte transplantation because of their multiple differentiation potential and nearly unlimited availability. They may differentiate into hepatocyte-like cells in vitro and maintain specific hepatocyte functions also after transplantation into the regenerating livers of mice or rats both under injury and non-injury conditions. Depending on the underlying liver disease their mode of action is either to replace the diseased liver tissue or to support liver regeneration through their anti-inflammatory and anti-apoptotic as well as their pro-proliferative action.

Abstract
A short half-life and low levels of growth factors in an injured microenvironment necessitates the sustainable delivery of growth factors and stem cells to augment the regeneration of injured tissues. Our aim was to investigate the ability of VEGF(165) expressing bone marrow mesenchymal stem cells (BMMSCs) to differentiate into hepatocytes when cultured with hepatocyte growth factor (HGF) and epidermal growth factor (EGF) in vitro. We isolated, cultured and identified rabbit BMMSCs, then electroporated the BMMSCs with VEGF(165)-pCMV6-AC-GFP plasmid. G418 was used to select transfected cells and the efficiency was up to 70%. The groups were then divided as follows: Group A was electroporated with pCMV6-AC-GFP plasmid + HGF + EGF and Group B was electroporated with VEGF(165)-pCMV6-AC-GFP plasmid +HGF + EGF. After 14 days, BMMSCs were induced into short spindle and polygonal cells. Alpha-fetoprotein (AFP) was positive and albumin (ALB) was negative in Group A, while both AFP and ALB were positive in group B on day 10. AFP and ALB in both groups were positive on day 20, but the quantity of AFP in group B decreased with prolonged time and was about 43.5% less than group A. The quantity of the ALB gene was increased with prolonged time in both groups. However, there was no significant difference between group A and B on day 10 and 20. Our results demonstrated that VEGF(165)-pCMV6-AC-GFP plasmid modified BMMSCs still had the ability to differentiate into hepatocytes. The VEGF(165) gene promoted BMMSCs to differentiate into hepatocyte-like cells under the induction of HGF and EGF, and reduced the differentiation time. These results have implications for cell therapies.

Abstract
Without therapeutic intervention acute liver failure (ALF) is the consequence of a progredient destruction of the liver parenchyma due to metabolic exhaustion of the hepatocytes. Perivenous hepatocytes are responsible for the detoxification of noxious compounds via the cytochrome P450 enzyme system. Liver transplantation is the only remaining therapeutic option in the end-stage of the disease. Assuming that metabolic capacity could be provided by healthy hepatocytes and thus substitute for the genuine parenchymal cells hepatocyte transplantation since quite some time is considered to be an alternative to whole liver transplantation. While this hypothesis achieved proof-of-concept in animal trials clinical breakthrough is still awaiting success, the reasons of which are ongoing matter of debate. In recent times mesenchymal stem cells (MSC) came into focus as a transplantable cell source to treat ALF. Interestingly, as demonstrated in various rodent animal models their mode of action is rather based on trophic support of hepatocytes remaining in the damaged host parenchyma rather than substitution of tissue loss. Mechanistically, either direct or indirect paracrine effects from the transplanted cells acting pro-proliferative, anti-apoptotic, and anti-inflammatory seem to trigger the regenerative response of the residual healthy hepatocytes in the otherwise lethally injured liver parenchyma. Thus, allogeneic MSC may be the best choice for the treatment of ALF taking advantage of their short-term benefit to sustain the critical phase of the acute insult avoiding long-term immunosuppression.

Abstract
There are some evidences for suggesting that adipose derived stem cells (ADSCs) can be differentiated to the fate of neural cell type. ADSCs can be expanded rapidly in vitro and can be obtained by a less invasive method. In this study, we attempted to compare the stability of neural differentiation in human ADSCs by using two induction protocols. Isolated ADSCs were induced into neural-like cells using diverse effects of two specific procedures. For protocol 1, ADSCs were induced by chemical induction. In protocol 2, ADSCs were treated for sphere formation. Then, the singled cells were cultured in neurobasal media supplemented with special components. Differentiated ADSCs were evaluated for Nestin, MAP2 and GFAP expression by immunocytochemistry and semi quantitative RT-PCR techniques. Moreover, MTT assay was employed to detect cell viability and proliferation. Immunocytochemical analysis of both protocols demonstrated that ADSCs had large expression of the neural-specific markers. In RT-PCR, protocol 1 showed the highest percentage of MAP2 expression, but with time passing, the neural like state was reversible. Protocol 2 found with express of Nestin at week 1, however MAP2 and GFAP expression increased after 3 weeks. The neural-like cells produced by protocol 1 led to the further cell death. Comparative analysis showed that neural-like cell differentiation of ADSCs in chemical induction protocol was rapid but transitory, while it was approximately steady in neurosphere formation protocol.

Abstract
OBJECTIVES It was unclear whether systemically administered mesenchymal stem cells (MSCs) labeled with magnetic nanoparticles can transdifferentiate into hepatocytes. In the present study, we built a new in vivo murine model for monitoring the transdifferentiation of magnetically labeled green fluorescent protein (GFP) positive MSCs into albumin-positive hepatocytes, under the carbon tetrachloride (CCl4) induced persistent liver damage. We also tracked magnetically labeled MSCs by using magnetic resonance imaging (MRI) in vivo. MATERIALS AND METHODS Among the liver damage groups, magnetically labeled GFP-positive MSCs (group A), GFP-positive MSCs (group B), and saline alone (group C) were intravenously injected. In control groups without CCl4 administration magnetically labeled GFP-positive MSCs (group D) were infused, whereas nothing was given in group E. MRI examinations were performed 24 hours and 4 weeks after cell injection in group A, B, and C. Liver-to-muscle contrast-to-noise ratios on T2*-weighted MR images were measured. At 4 weeks, 3 serum biologic liver function markers were analyzed, and mice in all groups were killed for histologic examination. RESULTS The results showed that migration of transplanted magnetic labeled cells to the liver was successfully documented with in vivo MRI. Serum liver function markers were changed for all liver damage groups than nondamage control groups (P < 0.05), but still insignificant compared with group C (P > 0.05). Hematoxylin and eosin and Masson staining confirmed the presence of liver damage and hepatic fibrosis in group A, B, and C. Positive Prussian blue stained cells were highly correlated with GFP-positive cells in group A with an average matching rate of 95%. In group D, no iron-GFP-positive cells can be found in the liver. Albumin was expressed in (34% ± 6%) and (35% ± 7%) of GFP-positive cells in group A and B, respectively, and there was no significant difference between the 2 groups. CONCLUSIONS Our data demonstrate that magnetic labeling technique synchronized well in GFP expressing MSCs and did not interfere with the transdifferentiation process and amending function of MSCs in vivo. Both magnetically labeled and unlabeled MSCs appeared to have the potential to differentiate into hepatocytes.

Abstract
The aim of the study was to develop a new strategy for the differentiation of hematopoietic stem cell (HSC) derived from UCB into hepatocyte like cells and also to estimate the effects of combination of fibroblast growth factor 4 (FGF 4) and hepatocyte growth factor (HGF) on hematopoietic stem cell differentiation. HSCs were isolated and purified by magnetic activated cell sorting. HSCs were induced to hepatocyte like cells under a 2-step protocol with combination of growth factors. Reverse transcription polymerase chain reaction was performed to detect multiple genes related to hepatocyte like cells development and function. Hepatocyte like morphology was illustrated by inverted repeat microscope and the secretion of albumin and α- fetoprotein by these cells was confirmed by enzyme linked immunosorbent assay. Hepatocyte like cells was observed at the end of the protocol (days 14). These differentiated cells were observed to show high expression of genes related to hepatocytes (tryptophan 2, 3-dioxygenase [TO], glucose 6-phosphate [G6P], cytokeratin 18 [CK 18], albumin and α- fetoprotein [AFP]). The quantities of albumin and AFP at day 0 were low and upon differentiation the cells were able to produce albumin and AFP at high levels. Our results show a new strategy for differentiation in a short duration, using a combination of growth factors for the differentiation of umbilical cord blood derived HSC into hepatocyte like cells under certain in vitro conditions. After further studies this approach has the potency, for widespread cell replacement therapy for liver diseases.

Abstract
Bone marrow mesenchymal stem cells (BM-MSCs) are a kind of multipotent stem cells that have the capacity to undergo self-renewal and multi-lineage differentiation. In an appropriate microenvironment, BM-MSCs can differentiate into bone, cartilage, fat, nerve, liver or other cells. Based on this characteristic, BM-MSCs might be used as new seed cells for orthotopic liver transplantation and bioartificial liver support system. This paper reviews the recent advances in research on the use of BM-MSCs as a treatment for acute liver failure.

Abstract
The hepatocyte is the smallest functional entity of the liver and executes the majority of this organ's -metabolic functions. Hence, hepatocyte transplantation has become a versatile alternative to whole organ liver transplantation. This novel treatment option is based on the assumption that transplanted -hepatocytes integrate into the host liver, proliferate at the site of tissue damage, take over the long-term hepatic -synthetic capacity, and thus substitute for the diseased host tissue. However, clinical success is still waiting for a breakthrough, likely because of two major reasons including (1) the scarcity of cadaveric donor livers and (2) the largely poor quality of cells isolated from marginal quality donor organs. Therefore, alternative cell sources have to be established to further prompt the clinical success of hepatocyte transplantation. Due to their multiple differentiation potential and nearly unlimited availability, stem cells are an attractive -alternate resource. Because of both clinical and ethical objections, adult stem cells are often preferred over embryonic stem cells as a starting material. Recent studies have demonstrated the ability of mesenchymal stem cells derived from various tissues to differentiate into hepatocyte-like cells in vitro as well as showing specific hepatocyte functions in vivo after transplantation into the livers of mice or rats.

Abstract
We tested whether bone marrow stromal cells (BMSCs) could enhance the survival and neurite growth of dorsal root ganglia (DRG) through substrate effects or secreted factors. Our results showed that in DRG with BMSCs and BMSC-conditioned media cultures compared with DRG-fibroblast cultures, there was a significant increase in the number and length of, area covered by, and number of cells with definite neurites. In cytokine assays with conditioned media, vascular endothelial growth factor, granulocyte macrophage colony-stimulating factor, and IL-6 secreted by BMSCs may contribute to observed neurotrophic effects. These findings indicate that BMSCs of adult Macaca fascicularis increased neuronal survival and promoted neurite outgrowth of DRG by means of secretory factors.

Abstract
Hepatocytes are vulnerable to loss of function and viability in culture. Modified culture methods have been applied to maintain their functional status. Heterotypic interactions between hepatocytes and nonparenchymal neighbors in liver milieu are thought to modulate cell differentiation. Cocultivation of hepatocyte with various cell types has been applied to mimic the hepatic environment. Bone marrow stromal cells (BMSC) are plastic cell lines capable of transforming to other cell types. In this study hepatocyte coculture with BMSCs achieved long-term function of human hepatocytes in culture for 4 weeks. In vitro functional status of human hepatocytes in BMSC coculture was compared with fibroblast coculture and collagen culture by measuring albumin, human-α-1-antitrypsin (hAAT), urea secretion, CYP450 activity, and staining for intracellular albumin and glycogen. After 2 weeks in culture hepatocytes were retrieved and transplanted to severe combined immunodeficiency/albumin linked-urokinase type plasminogen activator (SCID Alb-uPA) mice and engraft-ment capacity was analyzed by human hepatic-specific function measured by hAAT levels in mouse serum, and Alu staining of mouse liver for human hepatocytes. Hepatocytes from BMSC coculture had significantly higher albumin, hAAT secretion, urea production, and cytochrome P450 (CYP450) activity than other culture groups. Staining confirmed the higher functional status in BMSC coculture. Transplantation of hepatocytes detached from BMSC cocultures showed significantly higher engraftment function than hepatocytes from other culture groups measured by hAAT levels in mouse serum. In conclusion, BMSC coculture has excellent potential for hepatocyte function preservation in vitro and in vivo after transplant. It is possible to use BMSC hepatocyte coculture as a supply of cell therapy in liver disease.

Abstract
OBJECTIVES Alginate scaffolds are the most frequently investigated biomaterials in tissue engineering. Tissue engineering techniques that generate liver tissue have become important for treatment of a number of liver diseases and recent studies indicate that bone marrow-derived stem cells (BMSCs) can differentiate into hepatocyte-like cells. The goal of the study described here, was to examine in vitro hepatic differentiation potential of BMSCs cultured in an alginate scaffold. MATERIALS AND METHODS To investigate the potential of BMSCs to differentiate into hepatocyte-like cells, we cultured BMSCs in alginate scaffolds in the presence of specific growth factors including hepatocyte growth factor, epidermal growth factor and fibroblast growth factor-4. RESULTS We can demonstrate that alginate scaffolds are compatible for growth of BMSCs and when cultured in alginate scaffolds for several days they display several liver-specific markers and functions. Specifically, they expressed genes encoding alpha-foetoprotein, albumin (ALB), connexin 32 and CYP7A1. In addition, these BMSCs produced both ALB and urea, expressed cytokeratin-18 (CK-18) and were capable of glycogen storage. Percentage of CK-18 positive cells, a marker of hepatocytes, was 56.7%. CONCLUSIONS Our three-dimensional alginate scaffolds were highly biocompatible with BMSCs. Furthermore, culturing induced their differentiation into hepatocyte-like cells. Therefore, BMSCs cultured in alginate scaffolds may be applicable for hepatic tissue engineering.

Abstract
Adult bone marrow-derived mesenchymal stem cells (MSCs) exist in all living species and are capable of differentiating into different types of specific cells. In this study, we demonstrate the therapeutic effectiveness of rat MSC transplantation in D-galactosamine (GalN)-induced acute liver injury and identified the novel pathways which are involved in hepatic differentiation of MSCs. In vivo, intraportal transplantation with 5 × 10(6) MSCs at 24 hours after GalN administration resulted in significant reduction in serum levels of alanine aminotransferase, aspartate aminotransferase, and total bilirubin compared to the control group. Engrafted MSCs actively proliferated, differentiated, and further enhanced hepatocyte proliferation activity. In vitro, coculture of MSCs with GalN-induced injured hepatocytes showed efficient differentiation and was evidenced by progressive increase in messenger RNA levels of hepatic markers, including albumin, α-fetoprotein, CCAAT-enhancer binding protein α, α-1-antitryspin, and hepatocyte nuclear factor-3β. Immunofluorescent staining revealed that these cells were positive for albumin, α-fetoprotein, and cytokeratin 18, but not clusters of differentiation 34, cytokeratin 19, or OV6. During hepatic differentiation, signal transducer and activator of transcription 3 (STAT3) and mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) signaling were constantly activated, and a gradual down-regulation of β-catenin expression in messenger RNA and protein levels was detected. Hyper-interleukin-6 fusion protein but not interleukin-6 (IL-6) alone caused reduction in β-catenin expression associated with the up-regulation of Wnt-5a in MSCs via activating the glycoprotein 130 (gp130)-mediated STAT3 signaling pathway, which indicates the operation of the trans-signaling mechanism. Activation of IL-6/gp130-mediated STAT3 signaling pathway in MSCs triggered wound healing, cell migration, and proliferation. In conclusion, transplantation of MSCs promotes cell proliferation and organ repair, and activation of IL-6/gp130-mediated STAT3 signaling pathway via soluble IL-6 receptor is crucial in hepatic differentiation of MSCs.

Abstract
Cell transplantation is a promising strategy for the treatment of neurodegenerative and muscle degenerative diseases. Many kinds of cells, including embryonic stem cells and tissue stem cells, have been considered as candidates for transplantation therapy. Bone marrow stromal cells (MSCs) have great potential as therapeutic agents since they are easy to isolate and can be expanded from patients without serious ethical or technical problems. We discovered a new method for the highly efficient and specific induction of functional Schwann cells, neurons and skeletal muscle lineage cells from both rat and human MSCs. These induced cells were transplanted into animal models of neurotraumatic injuries, Parkinson's disease, stroke and muscle dystrophies, resulting in the successful integration of transplanted cells and an improvement in behavior of the transplanted animals. Here we focus on the respective potentials of MSC-derived cells and discuss the possibility of clinical application in degenerative diseases.

Abstract
Donor organ shortage is still the major obstacle for the clinical application of hepatocyte transplantation in the treatment of liver diseases. However, generation of hepatocyte-like cells from mesenchymal stem cells (MSCs) has become a real alternative to the isolation of primary hepatocytes. MSCs are extracted from the tissue by collagenase digestion and enriched by their capacity to grow on plastic surfaces. Enriched cells display distinct mesenchymal surface markers and are capable of multiple lineage differentiation. In the presence of specific growth conditions, the cells adopt functional features of differentiated hepatocytes. After orthotopic transplantation, differentiated human stem cells engraft in the host liver parenchyma of immunocompromised mice. This protocol describes the in vitro differentiation of stem cells from human bone marrow and their transplantation into livers of immunodeficient mice. The cell culture procedures take about 4-5 weeks, and cells engrafted in the mouse liver may be detected 2-3 months after transplantation.

Abstract
AIM: To evaluate the possibility of differentiation and malignant transformation of bone marrow stromal cells (BMSCs) in a mouse model of chemical hepatocarcinogenesis.
METHODS: BMSCs were harvested from male BALB/c mice, cultured and transplanted into the liver of female syngeneic BALB/c mice via the portal vein. Diethylnitrosamine was administered to mice for six months to induce hepatocarcinogenesis. Six months later, liver samples were taken and used to evaluate the expression of placental form of glutathione-S-transferase, α-fetoprotein and cytokeratin 19 by immunohistochemistry. Y chromosome-positive hepatocytes were detected by fluorescence in situ hybridization (FISH).
RESULTS: BMSCs were shown to differentiate into hepatocyte-like phenotypes after hepatocyte growth factor treatment in vitro. Twenty-six percent of recipient mice survived and developed multiple hepatocellular carcinomas (HCCs). Immunohistochemically, HCCs expressed placental form of glutathione-S-transferase and α-fetoprotein, but did not express cytokeratin 19. Y chromosome-positive hepatocytes were detected by FISH in the liver of mice that were treated with diethylnitrosamine after BMSC transplantation while no such hepatocytes were identified in the liver of mice that were not treated with diethylnitrosamine. No hepatocellular carcinoma cells positive for Y chromosome marker were detected.
CONCLUSION: Transplanted BMSCs can differentiate into hepatocytes but have low malignant potential in the mouse model of chemical hepatocarcinogenesis.

Abstract
OBJECTIVE The aim of this study was to test the protective effect of mesenchymal stem cells (MSCs) on cardiomyocytes in vitro and to investigate the anti-apoptotic signaling pathway. METHODS MSCs from Sprague-Dawley (SD) rats were separated and cultured. MSC medium was collected from MSCs cultured in serum-free Dulbecco's modified eagle medium (DMEM) under hypoxia. Cultured cardiomyocytes from neonatal SD rats were exposed to hypoxia/reoxygenation (H/R) and treated with MSC medium. The apoptotic cardiomyocytes were stained with Annexin-V-fluorescein isothiocyanate (FITC), Hoechst 33342 and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). The mitochondrial transmembrane potential of cardiomyocytes was assessed using a fluorescence microscope. The expression of Bcl-2, Bax, cytochrome C, apoptosis-induced factor (AIF), and caspase-3 was tested by Western blot analysis. RESULTS Our data demonstrated that MSC medium reduced H/R-induced cardiomyocyte apoptosis, increased the Bcl-2/Bax ratio, and reduced the release of cytochrome C and AIF from mitochondria into the cytosol. CONCLUSION MSCs protected the cardiomyocytes from H/R-induced apoptosis through a mitochondrial pathway in a paracrine manner.

Existing clinical imaging procedures lack sensitivity and specificity in detecting early prostate cancer bone metastatic lesions. In this study, we developed a highly reproducible bone metastasis xenograft model and identified possible molecular imaging candidates for detecting early bone metastatic lesions. Bone trophic human prostate cells (PC-3B1) were isolated and characterized for their ability to reach bone after intracardiac injection into SCID mice. The appearances of skeletal metastases were evaluated using digital radiographic imaging and confirmed by necropsy and histology. The PC-3B1 cells retain a bone homing phenotype after long term propagation in tissue culture and exhibit progressive bone lesions within 3 weeks following intracardiac injection. Comparative transcription signatures of PC-3 and PC-3B1 cells were determined using a cancer specific microarray and confirmed by RT-PCR analysis. The analysis identified increased expression of four cell surface molecules in PC-3B1 cells that may be suitable as molecular imaging candidates to detect bone micro metastases.

Abstract
Transplantation of hepatocytes or bone marrow-derived cells has been shown to ameliorate liver fibrosis in animal models, but no direct comparison of relative efficiency has been made. The aim of this study was to compare the efficiency of a bone marrow-derived clonal mesenchymal stem cell line established by us (rBM25/S3) with that of its adipogenic or hepatogenic differentiation derivative for suppression of rat liver fibrosis. After induction of differentiation of rBM25/S3 cells into adipogenic or hepatogenic cells in culture, we intrasplenically transplanted the three types of cells into rats (3 x 10(7) cells/rat) before and 4 weeks after initiation of carbon tetrachloride treatment (1 ml/kg body weight twice a week for 8 weeks) to induce liver fibrosis. Undifferentiated rBM25/S3 cells were the most effective for suppression of liver fibrosis, followed by the adipogenic cells and hepatogenic cells. Expression levels of MMP-2 and MMP-9 were also highest in undifferentiated rBM25/S3 cells. These results indicate that bone marrow-derived clonal mesenchymal stem cell lines are useful for further mechanistic studies on cell-mediated suppression of liver fibrosis and that such cell lines will provide information on an appropriate cell source for transplantation therapy for cirrhosis.

Abstract
Adipose tissue contains a mesenchymal stem cell (MSC) population known as adipose-derived stem cells (ASCs) capable of differentiating into different cell types. Our aim was to induce hepatic transdifferentiation of ASCs by sequential exposure to several combinations of cytokines, growth factors, and hormones. The most efficient hepatogenic protocol includes fibroblastic growth factors (FGF) 2 and 4 and epidermal growth factor (EGF) (step 1), hepatocyte growth factor (HGF), FGF2, FGF4, and nicotinamide (Nic) (step 2), and oncostatin M (OSM), dexamethasone (Dex), and insulin-tranferrin-selenium (step 3). This protocol activated transcription factors [GATA6, Hex, CCAAT/enhancer binding protein alpha and beta (CEBPalpha and beta), peroxisome proliferator-activated receptor-gamma, coactivator 1 alpha (PGC1alpha), and hepatocyte nuclear factor 4 alpha (HNF4alpha)], which promoted a characteristic hepatic phenotype, as assessed by new informative markers for the step-by-step hepatic transdifferentiation of hMSC [early markers: albumin (ALB), alpha-2-macroglobuline (alpha2M), complement protein C3 (C3), and selenoprotein P1 (SEPP1); late markers: cytochrome P450 3A4 (CYP3A4), apolipoprotein E (APOE), acyl-CoA synthetase long-chain family member 1 (ACSL1), and angiotensin II receptor, type 1 (AGTR1)]. The loss of adipose adult stem cell phenotype was detected by losing expression of Thy1 and inhibitor of DNA binding 3 (Id3). The reexpression of phosphoenolpyruvate corboxykinase (PEPCK), apolipoprotein C3 (APOCIII), aldolase B (ALDOB), and cytochrome P450 1A2 (CYP1A2) was achieved by transduction with a recombinant adenovirus for HNF4alpha and finally hepatic functionality was also assessed by analyzing specific biochemical markers. We conclude that ASCs could represent an alternative tool in clinical therapy for liver dysfunction and regenerative medicine.

Abstract
AIM: To evaluate cooperative effects on swine acute liver failure by combined therapy of autologous mesenchymal stem cell transplantation and medical treatment.
METHODS: Pigs were given D-galactosamine to build models of acute liver failure. Twelve miniature pigs were randomly divided into four groups. In combined therapeutic group, 5 × 107 MSCs were injected into liver via portal veins after 24 h, 100 mL plasma and diammonium glycyrrhizinate 100 mg in vein QD. In the medical treatment group, blood plasma 100 ml and diammonium glycyrrhizinate 100 mg in vein QD. In the MSCs transplantation group, 5 × 107 MSCs were injected into liver via portal veins after 24 h. In the control group, except for routine observation and care, no additional treatment was given. Liver function and pathological changes were measured.
RESULTS: The survival time of the control group was 44 ± 3.5 h, promoting all experimental animals to death at 48 h. The biochemical assay of the combined therapeutic group were different from those in the medical treatment group and from the MSCs transplantation group (P < 0. 05), as well as from the biochemical assay. Area of necrosis was obviously reduced in the combined therapeutic group. Cells grow rate (34%) in the combined therapeutic group was remarkably different from those of other groups.
CONCLUSION: The medical treatment and the MSCs transplantation are useful for ALF partially. The combined therapy shows cooperativeeffects, and the biochemical assay and changes in liver pathology are significantly improved.

Abstract
BACKGROUND Bone marrow mesenchymal stem cell (MSC) transplantation is a promising strategy in the treatment of myocardial infarction (MI). However, the time for transplanting cells remains controversial. The aim of this study was to find an optimal time point for cell transplantation. METHODS MSCs were isolated and cultured from Sprague-Dawley (SD) rats. MI model was set up in SD rats by permanent ligation of left anterior descending coronary artery. MSCs were directly injected into the infarct border zone at 1 h, 1 week and 2 weeks after MI, respectively. Sham-operated and MI control groups received equal volume of phosphate buffered saline (PBS). At 4 weeks after MI, cardiac function was assessed by echocardiography; vessel density was analyzed on hematoxylin-eosin stained slides by light microscopy; the apoptosis of cardiomyocytes was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay; the expressions of proteins were analyzed by Western blot. RESULTS MSC transplantation improved cardiac function, reduced the apoptosis of cardiomyocytes and increased vessel density. These benefits were more obvious in 1-week group than in 1-h and 2-week groups. There are more obvious increases in the ratio of bcl-2/bax and the expression of vascular endothelial growth factor (VEGF) and more obvious decreases in the expression of cleaved-caspase-3 in 1-week group than those in other two groups. CONCLUSION MSC transplantation was beneficial for the recovery of cardiac function. MSC transplantation at 1 week post-MI exerted the best effects on increases of cardiac function, anti-apoptosis and angiogenesis.

Canine bone marrow cells differentiate into hepatocyte-like cells and placental hydrolysate is a potential inducer. Res Vet Sci 2009; 87:1-6. [PMID: 19121529 DOI: 10.1016/j.rvsc.2008.11.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2008] [Revised: 11/10/2008] [Accepted: 11/19/2008] [Indexed: 01/29/2023]
Abstract
Hepatocyte growth factor (HGF) can stimulate human and rat bone marrow (BM) cells to differentiate into hepatocytes. A human placental hydrolysate (hPH) stimulates proliferation of hepatocytes, but its role as a potential inducer of BM cells to form hepatocytes is unclear. To determine if canine BM cells stimulated with HGF or hPH differentiate into hepatocyte-like cells, BM cells were cultured with HGF or hPH. The cultured cells underwent morphological examination, expression of albumin and cytokeratin 18 (CK18), hepatic function tests including uptake of low-density lipoprotein (LDL) and cytochrome P (CYP) 450 activity. Albumin mRNA and protein expression of albumin and CK18 proteins were detected in cultures with HGF and hPH. Furthermore, these cells demonstrated LDL uptake and CYP450 activity. These results indicate that canine BM cells can differentiate into hepatocyte-like cells when stimulated by both HGF and that hPH may be an effective inducer of hepatic differentiation.

Abstract
AIM: To isolate and identify mouse marrow stromal stem cells (MSCs), then to explore whether MSCs cultured in the directed differentiation media including HGF, EGF and FGF-4 could differentiate into hepatocytes.
METHODS: Bone marrow cells were collected from C57BL/6 mouse by density gradient centrifugalization, and were purified by adherent culture. Cell morphology was observed, and cell surface markers were identified by flow cytometry. MSCs were cultured in the directed differentiation media including HGF, EGF and FGF-4, and the expression patterns of some genes of the hepatocytes, AFP, ALB and CK18 were validated and confirmed by RT-PCR. The ALB and CK18 expressed cells were confirmed by Western blot.
RESULTS: Cell morphology tended to be uniform fusiform shape with passage. The percentage of hematopoietic lineage marker CD45 decreased from 86.49% to 2.77% while the percentage of CD90 increased obviously from 25.42% in primary culture cells to 93.47% at the fifth generation. AFP mRNA expression appeared on culture day 7 and decreased in the later days; ALB and CK18 mRNA expression also appeared on culture day 7, but increased with the differentiation of MSCs. ALB and CK18 were confirmed to express in the differentiated MSCs by Western blot analysis.
CONCLUSION: MSCs can be isolated and purified in vitro, then induced to differentiate into hepatocytes or hepatocyte-like cells by directed differentiation media including HGF, EGF and FGF-4.

Abstract
AIM: To investigate differentiation of rat bone marrow mesenchymal stem cells (MSCs) into hepatocyte-like cells.
METHODS: A total of 24 Wistar rats were randomly divided into 3 groups: normal group, hepatic fibrosis model group and Chinese medicine treatment group. The model of liver fibrosis was induced by subcutaneous injection of CCl4. After the model was successfully developed, and the rats in Chinese medicine treatment group were fed with Danjin Shugan capsule. At the end of treatment, the rats were killed and the livers were obtained. Histopathological changes were evaluated by hematoxylin and eosin staining. MSCs were isolated by gradient density centrifugation and plastic adherence and then purified. The purified MSCs in each group were cultured with hepatocyte growth factor (HGF) and fibroblast growth factor-4 (FGF-4). The levels of alpha-fetoprotein (AFP) and albumin (Alb) in the supernatant were determined by radioimmunoassay on days 15, 21 and 27. On day 27, the cells were collected for glycogen staining and CK-18 immunocytochemical analysis.
RESULTS: Compared with those in the non-induced MSCs among the three groups, the levels of AFP in the induced-MSCs were higher on days 15, 21, and 27, and reached to the peak value on day 21 (hepatic fibrosis model group: 48.94 ± 0.08 vs 9.90 ± 0.09; Chinese medicine treatment group: 49.86 ± 0.29 vs 8.69 ± 0.62; normal group: 38.65 ± 0.33 vs 9.04 ± 0.11; all P< 0.01). There were significant differences in Alb levels on days 21 and 27 between the induced and non-induced MSCs (1.11 ± 0.08 vs 0.32 ± 0.00, 1.25 ± 0.04 vs 0.32 ± 0.00, 1.06 ± 0.03 vs 0.33 ± 0.00; 1.52 ± 0.02 vs 0.33 ± 0.00, 1.79 ± 0.01 vs 0.31 ± 0.03, 1.63 ± 0.04 vs 0.32 ± 0.01; all P < 0.01), but not on day 15; the peak level of Alb was on day 27. Both glycogen and CK-18 were positive on day 27 in the induced MSCs. According to AFP and Alb levels, the induced effects of Chinese medicine group were superior to those of the other two groups.
CONCLUSION: MSCs can differentiate into hepatocyte-like cells with hepatic phenotype and function in the presence of HGF and FGF-4, which may be used as a kind of cell resources to treat severe hepatic disease. Chinese medicine may optimize the induction of MSCs differentiation in vitro.
