(B) Representative photograph of Masson's trichrome staining of transverse sections of an injured gastrocnemius. Scale bar =100 μm. (C) Gastrocnemius wet weight ratio (weight of injured muscle to weight of normal muscle) in each group. (D) Average cross‐sectional area of muscle fibers in each group. Data are presented as the mean ±SD. ^* p <.05; ^** p <.01; N.S., no significant difference
