VEGF immunohistochemical expression in the wound tissue 1 week after wound induction. VEGF expression was more pronounced in the granulation tissue of the lyophilized AM group (C, F) than in that of the control (A, D) and fresh AM groups (B, E) at week 1 post-wounding. It was noted in the endothelial cells of newly created microvessels and in inflammatory and fibroblasts (arrowheads).
