Fig. 7

Microscopic images of the soleus muscle stained with cluster of differentiation 31 (CD31; a) and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL; b); c merged images of a and b. Scale bar: 50 μm. Arrowheads indicate TUNEL-positive endothelial cells. d Mean number of the TUNEL-positive endothelial cells of the soleus muscle in each group. Values are shown as the mean (bars) ± SEM (error bars). The asterisk (*), dagger (†), and double dagger (‡) indicate a significant difference from the CON, CON + PP, and HU groups, respectively, at P < 0.05
