Objective To investigate the effects of signal transducer molecules,P38 MAPK and nuclear factor-kappa B(NF-κB),on the hepatic differentiation of bone marrow mesenchymal stem cell(BMSCs)into hepatocyte-like cells under the mediation of hepatocyte growth factor(HGF)and liver tissue fluid(LTF). Methods BMSCs were isolated by whole bone marrow adherent culture.The third generation of BMSCs were cultured with HFG,LTF,or BAY 11-7082(an inhibitor of NF-κB).Indocyanine green(ICG)uptake assay was used to detect hepa...
