Capillary and arteriole densities in muscle tissue. (a) The ischemia-induced groups (G2–G5) showed a decrease in CD31+ capillary density compared to G1; however, no differences were noted based on the E-MSC dosage. (b) The α-smooth muscle actin (α-SMA) arteriole density was similar in all groups. (*, P < 0.05) (c) CD31 and α-SMA staining images on day 21. The capillary and arteriole appear brown in the image (×200 magnification). (Scale bar: 100 μm).
