Effects of MSC injection on fibrosis markers and collagen expression in CG-induced peritoneal fibrosis. a Immunohistochemical analyses of TGF-β1, a profibrotic marker, α-smooth muscle actin (α-SMA), a marker for myofibroblasts, collagen I and collagen III expressions in peritoneal tissues were performed on day 10 after MSC injection. b Graph showing the percentage of TGF-β1-positive areas or α-SMA-positive areas, and the area of collagen-I-positive staining or collagen-III-positive staining, per group. We measure 50 fields from 5 rats per group. Abbreviations are as in Fig. 1. *P < 0.05 (Kruskal–Wallis test)
