Nanofat and FE work synergistically to promote fat graft survival. a The design of the second animal study. b Macroscopic images of the fat grafts at 12 weeks post-transplantation. c Weights of the fat grafts at 12 weeks post-transplantation (*p < 0.05). d HE staining of the harvested fat grafts at 12 weeks post-transplantation. Scale bars = 100 μm. e Histologic analysis to evaluate the grafts at 12 weeks post-transplantation. The percentage areas of integrity, vacuoles and fibrosis were calculated (*p < 0.05)
