Fig. 2

Representative confocal laser scanning microscopic images of the three-dimensional (3D) capillary architecture of the soleus muscle of a rat in the CON (a), CON + PP (b), HU (c), and HU + PP (d) groups. Scale bar: 100 μm. e, f Mean capillary luminal diameter (e) and capillary volume (f) in the soleus muscle of 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
