Abstract

There are numerous studies which provide support for the use of human adipose tissue-derived stem cells (hASCs) to generate hepatocyte-like cells. However, the produced cells exhibit only a certain level of differentiation, mainly due to inefficient induction conditions. Therefore, based on the important role of insulin-like growth factor (IGF-I) in hepatic function and development, in the current study we evaluated the differentiation efficacy of the mentioned factor to induce hASCs into functional hepatocyte-like cells. To investigate this, using a two-step protocol, hASCs were treated with a combination of HGF, Dex, and OSM in the presence or absence of IGF-I up to 21 days. Hepatic differentiation was evaluated by analyzing specific hepatocyte markers at different time points of differentiation induction. Increased expression of hepatocyte-specific genes including ALB, AFP, CK18, and HNF4a, downregulation of bile duct cells marker (CK19), the higher number of ALB positive cells, increased urea production together with higher glycogen deposit was observed upon the treatment of hASCs with the induction medium containing IGF-I compared to the other treatment. In conclusion, our findings suggest IGF-I as a potent inducer of hepatic differentiation of hASCs and its potential to generate more functional hepatocyte-like cells.
