Suppression of hepatic fibrosis by IC-2 sheets on the ninth day after transplantation. (A) Protocol of the animal experiment. Abbreviations: p.o., per os; Tx, transplantation. “p.o.” indicates oral administration of CCl4. “Tx” indicates transplantation of cell sheets. (B) Micrographs of liver sections subjected to Azan staining (upper), Sirius red staining (middle), and immunohistochemistry for type I collagen (lower). MSC, mesenchymal stem cell. (C) The proportions of fibrotic areas among the groups (n = 7–9 except for n = 3 for CCl4(−) group). CCl4(−) indicates control mice without CCl4 intoxication. (D) Hydroxyproline contents in the liver (n = 6 except for n = 3 for CCl4(−) group). (E) Western blot of type I collagen in recipient liver tissues. The results are expressed as the mean ± S.E.M. Levels of significance: *P < 0.05; **P < 0.01 (one-way ANOVA followed by Games–Howell test).
