Preconditioning hADSCs with modVEGF improves fat graft survival in vivo. a Schematic illustration and design of the animal study. b, c Quantification of b VEGF-A in vivo produced protein and c HIF1α protein levels in fat grafts at days 1, 2, 3, 4, 5, and 6 post-transplantation. (n = 3) d Representative gross morphological images of fat grafts at 15, 30, and 90 days post-transplantation. e–g Weights of the fat grafts at 15, 30, and 90 days post-transplantation. (n = 6) Error bars showed means ± SD. (*p† < 0.05, **p† < 0.01, ***p† < 0.001, ****p† < 0.0001)
