Systemic Treatment of Acute Liver Failure with Adipose Derived Stem Cells

ABSTRACTPurpose of the study: The definitive treatment for liver failure is, currently, liver transplantation. Research into other possible treatments, focused on achieving regeneration of the liver parenchyma, have led to the development of methods to generate hepatocytes from stem cells. In our study, we transplant allogenic adipose-derived stem cells (ASCs), not previously differentiated to hepatocytes, to treat acute liver failure induced by intraperitoneal administration of carbon tetrachloride (CCl4) in a Sprague-Dawley rat model. Material and Methods: The ASCs were delivered via the tail vein, having previously been labeled with PKH26, a fluorescent membrane marker. Two control groups were established, Group 1(n = 15) consisting of olive oil (5 mL/kg) and Group 2(n = 15): 1 × 106 PKH26-labeled ASCs. Further, two study groups, Group 3(n = 30): CCl4 dissolved in olive oil and Group 4(n = 30): CCl4 dissolved in olive oil and 1 × 106 PKH26-labeled ASCs completed the experimental design.Results: Blood s...
