Effect of transplantation of BMSCs-IGF-1 following MI. a One week after coronary ligation, BMSCs-NC or BMSCs-IGF-1 (1 × 106) were injected via the tail vein. Three weeks later, the fibrosis region (blue) was determined by Masson’s trichrome stain and the protein levels of BAX, BCL-2, and caspase-3 were determined by immunohistochemistry. b Expression of BAX, BCL-2, and cleaved caspase-3 were determined by Western blotting (*P < 0.05, **P < 0.01, ***P < 0.001)
