Evaluation of muscle repair. a Histological analysis of semimembranosus muscle in normal and ischemic leg. b Histological analysis of gastrocnemius muscle in normal and ischemic leg. c Evaluation of muscle repair: percentage of muscle fibers with a central nucleus quantified in the ischemic gastrocnemius in comparison with its controlateral muscle (*comparison of MSCs group versus BMCs group; ^#S-MSCs versus BMCs; ^¥S-MSCs versus MSCs; ^§BMCs versus vehicle; ^ΔMSCs versus vehicle; ^∞S-MSCs versus vehicle)
