Fig. 4From: Exosomes from mesenchymal stem cells induce the conversion of hepatocytes into progenitor oval cellsParacrine signaling from MSCs upregulated mRNA expression of EpCAM and OC2 in hepatocytes. The mRNA expression level of alpha fetoprotein, cytokeratin 19, GGT, Thy1, CD34, Lgr5, DLK1, OC2, and EpCAM were analyzed in the hepatocytes by quantitative PCR. * P < 0.05; ** P < 0.01Back to article page
