Does transplantation of Adipose-Derived Mesenchymal Stem Cells Efficiently rescue Thioacetamide-Induced Acute Liver Failure in Mice? Context: We aimed to investigate the efficacy of adipose-derived mesenchymal stem cell (ADMSC) transplantation in acute liver failure caused by thioacetamide in mice as well as its underlying mechanism by comparing transplantation routes. ADMSCs were isolated from inguinal fat pads of enhanced green fluorescent protein (EGFP) transgenic mice and analyzed regarding their surface markers and differentiation potential. Acute liver failure models were established by infusion of thioacetamide, and then we injected EGFP-ADMSCs or phosphate-buffered saline solution by intrasplenic or intravenous route. The restoration of biologic functions of the livers receiving transplantation was assessed by means of a variety of approaches, such as survival rates, live function parameters, histology, localization of EGFP-ADMSCs, and immunofluorescence analysis. ADMSCs were positive for CD90 and CD44 and negative for CD34 and had adipogenic and osteogenic differentiation potential. And they prevented the release of liver injury biomarkers. Transplantation via tail vein provided a significant survival benefit, but no significant differences were observed in the intrasplenic pathway and between the 2 pathways in our animal experiments. Furthermore, the transplanted cells were well integrated into injured livers and produced albumin and cytokeratin-8.

Direct transplantation of ADMSCs is an effective treatment for acute liver failure rather than intrasplenic transplantation. The transplanted ADMSCs exhibit the potential to differentiate into hepatocyte-like cells in the injured livers. Thus, ADCMSCs would be a potential option for treatment of acute liver failure. Final Decision: yes
