Overexpression of transcription factor Foxa2 and Hnf1α induced rat bone mesenchymal stem cells into hepatocytes.

ABSTRACT: Hepatocytes differentiated from induced pluripotent stem cells and adult stem cells could be utilized as a tool for the study of liver diseases, screening for drug metabolism and hepatotoxicity. Thus further investigation of the method to efficiently generate hepatocytes is in great need. Bone Mesenchymal Stem Cells (BMSCs) were collected from rat femurs and tibias. FOXA2 and HNF1α genes were constructed into a lentiviral vector and introduced into BMSCs by a lentivirus-mediated overexpression system. Three weeks after the induction, the expressions of FOXA2 and HNF1α, and liver specific genes were analyzed, and hepatocyte-function related assays were performed. Overexpression of both FOXA2 and HNF1α induced the BMSCs to differentiate into hepatocyte-like cells (HLCs). Hepatocyte-specific
