Liver is the second most transplanted organ according to united network for organ sharing. Due to shortage of compatible donors, surgical difficulties, immunological hindrance and high post-operative cost, stem cell therapy is an attractive substitute of liver transplant for millions of patients suffering from hepatic failure. Due to several technical limitations such as viral integration, inefficient differentiation and adult phenotypes and epigenetic memory of fibroblasts, iPSCs, MSCs or i-Heps may not present a great clinical substitute for liver transplant. We pioneered a novel technology for robust expansion of quiescent liver stem cells (LSCs) from mice via utilizing of hedgehog agonist HhAg1.5 for 3 weeks. These expanded LSCs retained stem like properties after multiple passaging and differentiated to hepatocytes and cholangiocytes. Grafting of ex vivo expanded LSCs in FRG KO mice, significantly increased life span compared to control group (p<0.001). Thus in this study, we provide a promising viable substitute for primary hepatocytes for regenerative medicine and for life-threatening metabolic liver diseases.
