Representative micrograph of hepatic tissue stained with Sirius red showing collagen deposition in various treatment groups. (A = Vehicle, B = CCl4, C = MSCs, D = SNP, E = SNP-MSCs). F) Quantitative analysis of fibrosis in different experimental groups. One way ANOVA was applied to check the significance of the data. All values are expressed as mean ± SEM. P-value < 0.05 was considered significant. *P < 0.05 for SNP-MSCs vs. CCl4; #P < 0.05 for SNP-MSCs vs. MSCs; φP < 0.05 for SNP-MSCs vs. SNP.
