[Abstract] Objective To investigate the effect of wingless-type MMTV integration site family member 5b(Wnt5b) gene overexpression mediated by recombinant adenovirus on the differentiation of mouse embryonic liver stem cells and repair of chronic liver injury in mice. Methods Recombinant adenoviruses expressing Wnt5b and green fluorescent protein (GFP) were applied respectively to infect mouse fetal liver stem cells HP14-19, and induced its differentiation and verified the expression of Wnt5b through Real-time PCR and Western blotting. It also applied indocyanine grean(ICG) uptake experiment and periodic acid-schiff(PAS) staining to detect the differentiation ability of HP14-19 into hepatocyte-like cells. The Real-time PCR was chosen to detect hepatocyte markers albumin (Alb) and cytokeratin 18 (CK18) expression. Forty-eight experimental male BALB/ c mice were randomly divided into control group, model group, stem cell treatment group and Wnt5b modified stem cell treatment group. The carbon tetrachloride(CCl
