A The representative immunohistochemical images of extensor digitorum longus (EDL) muscle cells illustrated the localization of fast myosin and slow myosin in R1, P8-PBS and P8-MSC mice. The square denoted the same muscle cell (scale bar = 100 μm). B The percentage of fast myosin and slow myosin in EDL muscle cells of SAMP8 mice (PR1 & PBS = 0.0173; PMSC & PBS = 0.0050) (n = 8 or 10 views per group from 5–6 male mice; all data shown as mean ± SEM, *P < 0.05, **P < 0.01, ***P < 0.001).
