Muscle fiber size. (A) Cross-sections of soleus muscle stained with H & E from WB, HU, and HU-ES groups. Scale bar = 100 μm. Mean fiber cross-sectional area (μm²) of soleus (B) and EDL (C) muscles in the WB, HU, and HU-ES groups. *** P < 0.001, significant difference between WB and HU groups; ^# P < 0.05, significant difference between HU and HU-ES groups. n = 4. Data are means ± SEM.
