In vitro differentiation effect of CCL-induced liver injured mice serum on bone marrow-derived mesenchymal stem cells toward hepatocytes like cells.

Liver dysfunction is a major health problem worldwide. Stem cells therapy has opened up new avenues for researches to treat liver diseases due to their multi lineage differentiation. As mesenchymal stem cells (MSCs) can be differentiated into hepatic lineages in the presence of different exogenous factors, the current study aimed to investigate the impact of carbon tetrachloride (CCl) induced liver injured mice serum on MSCs differentiation toward hepatocytes in vitro. Male Balb/c mice were treated for liver injury with CCl as determined through biochemical tests spectrophotometrically and different growth factors (EGF, HGF) quantification through Sandwich ELISA in both normal and CCl-induced liver injured mice serum. Mice bone marrow derived-MSCs at second passage were treated with normal and CCl-induced liver injured mice serum. After 7 days, serum treated MSCs were investigated for hepatocytes like characteristics through RT-PCR. Serum biochemical tests (Bilirubin, ALT and ALP) and sandwich ELISA results of EGF and HGF showed marked increase in CCl treated mice serum as compared to normal mice serum Periodic acid Schiff's staining and urea assay kit confirmed high level of glycogen storage and urea production in cells treated with CCl-induced liver injured mice serum. RT-PCR results of CCl-induced liver injured mice serum treated cells also showed expression of hepatic markers (Albumin, Cyto-8, Cyto-18, and Cyto-19). This study confirmed that CCl-induced liver injured serum treatment can differentiate MSCs into hepatocyte-like cells in vitro.
