Immunohistochemical staining of CD31 in the wound area. 10x images showed more CD31-positive area (brown) in the VH298-treated wound, and 40x images showed more CD31-positive microvessels (brown) in the VH298-treated wound especially at the middle stage (14 days) of the wound healing process. Quantitative analysis showed more CD31-positive clusters in the VH298-treated group at all three time points. Graphs represent (VH298-treated vs. PBS-treated) (). D: day. and .
