Corticosterone repressed MSCs differentiation into MFs. Mice serum was collected and analyzed for ALT (a) and AST (b). Sirius Red staining ( × 100) (c) and liver hydroxyproline analysis (d) were done to detect liver fibrosis. Hematoxylin eosin (HE) staining was done to detect liver injury ( × 200) (e). MSCs were induced to differentiate into MFs in vitro. MFs differentiation efficiency of MSCs was determined by cytoimmunofluorescence assay (f). 4′,6-diamidino-2-phenylindole (DAPI) was used to stain nuclei (blue). OO, olive oil; CM, CCl4+MSCs group; CMS, CCl4+MSCs+stress group; CMSRU, CCl4+MSCs+stress+RU486 group; CMCor, CCl4+MSCs+corticosterone group; N, serum from normal mice; S, serum from stressed mice. RU, RU486; Cor, corticosterone. *P<0.05, **P<0.01
