ADSC-Exo promotes repair and vascularization of prefabricated flap graft wounds in vivo. (a) The repair process of prefabricated skin flaps in rats of each group. (b) Microscopic observation of the section showing the flap thickness in four groups. . (c) Masson staining for mature collagen. . (d) Microscopic observation of CD31 immunostaining. Brown reaction products means CD31-positive immunohistochemical staining and red arrow indicates mature blood vessels. . (e) The microvascular angiography of each group. (f) Quantitative analysis of the flap thickness in each group. (g) Quantitative analysis of the number of mature blood vessels. and .
