(a) Representative images of immunohistochemistry staining with the endothelial marker CD31 (400×, scale bars 50 μm). The density of microvessels that positively stained for CD31 was observed to be similar in the wound tissues among groups. (b) Western immunoblot analysis of CD31 expression in wound tissues. (c) Representative images of immunostaining with F4/80, a marker for macrophages (400×, scale bars 50 μm). (d) Western immunoblot analysis of F4/80 expression.
