Abstract :

The liver is a central multifunctional organ in our body. Hepatocyte dysfunction induced by viral hepatitis and cirrhosis may progress to liver failure. Stem cells (SCs) based therapy is a promising technique for the treatment of liver diseases. Umbilical cord derived mesenchymal stem cells (UC MSCs) do not express the major histocompatibility complex class II antigens thus they are potentially favorable SCs source for liver transplantation. The aim of our study was to investigate the in vitro UC MSCs hepatic differentiation potential. MSCs were cultured and induced to differentiate under pro-hepatogenic conditions using mainly hepatic growth factor (HGF) and fibroblastic growth factor. Differentiated hepatocyte-like cells were investigated based on three main criteria including its morphology, expression of hepatocyte specific genes, and specific functionality. After 21 days of treatment, the differentiated cells acquired hepatocytes-like oval shape. Using reverse transcriptase polymerase chain reaction (RT-PCR), the expression of hepatocyte-specific genes including albumin (ALB), ├?┬▒-fetoprotein (AFP) and cytokeratin-18 significantly increased in differentiated UC MSCs compared to control untreated cells (P<0.05). In addition, levels of albumin and AFP in the culture media showed a three folds increase in differentiated cells compared to control cells. We conclude that this protocol for the in vitro differentiation of UC MSCs produced viable functional hepatocytes. Our future goal is to test the in vivo effectiveness in treating end stage liver diseases.
