Fig. 2From: Fat extract improves fat graft survival via proangiogenic, anti-apoptotic and pro-proliferative activitiesHistological evaluation of grafts. a HE staining of the harvested fat grafts at 12 weeks post-transplantation. Scale bars = 100 μm. b Histologic analysis of the grafts at 12 weeks post-transplantation. The percentage areas of integrity, vacuoles and fibrosis were calculated (*p < 0.05). c Perilipin staining of the harvested fat grafts at 12 weeks post-transplantation. Scale bars = 50 μm. d The percentage area of viable adipocytes in the grafts at 12 weeks post-transplantation was calculated (*p < 0.05)Back to article page
