Evaluation of gastrocnemius muscle. a Gross observation of gastrocnemius muscle 8 weeks after implantation. Scar bar = 5 mm. b Statistical analysis of wet weight of gastrocnemius muscle. c Representative photomicrographs of gastrocnemius muscle. The cross sections of gastrocnemius muscle were stained by Masson’s trichrome. d Statistical analysis of myoatrophy was quantified by muscle fibers area and collagen fibers ratio. Data are presented as mean ± SEM, n = 6 rats per group, *P < 0.05 by ANOVA with post hoc Bonferroni correction
