a Plantar blood flow at rest, b walking distance, and c weight of muscles in each ischemic model (shown in Fig. 1a) at 4 weeks after iliac artery occlusion. Tibialis anterior (TA, red bar); extensor digitorum longus (EDL, yellow bar); soleus (SOL, green bar); gastrocnemius (GC, blue bar). Values are presented as the percentage to mean values of Sham group. n = 5–6 rats per group. Values are presented as mean ± SE and statistical significance was determined using Dunnett’s test. *P < 0.05, **P < 0.01, ***P < 0.001, vs. Sham group. ^##P < 0.01, vs. IAO group
