Fat grafting procedures are considered to be a promising regenerative, cell-directed therapy; however, their survival is mainly influenced by ischemia condition. Fructose 1,6-bisphosphate (FBP), as an intermediate in energy metabolism, has the potential to rescue cells and tissues from hypoxic-ischemic circumstances. In the present study, human lipoaspirates were grafted subcutaneously into nude mice followed by a daily intraperitoneal injection of FBP at different doses for 7 days. Next, the grafts were harvested at different time points till 12 weeks postimplantation and were evaluated for cell viability and function, tissue revascularization and inflammatory cell infiltration using histological analysis, whole-mount living tissue imaging, glycerol 3-phosphate dehydrogenase activity assays, and quantitative analysis of gene expression. The results demonstrated that exogenous FBP administration could attenuate the volume and weight reduction of fat graft; meanwhile, FBP enhanced adipocyte viability and function, increased blood vessel formation, and decreased inflammation. Moreover, in vitro cell experiments showed that FBP could promote adipose-derived stem cell viability and vascular endothelial growth factor (VEGF) mRNA expression in ischemia conditions. Our study indicates that FBP can be used as a protective agent for fat grafting and may be applied in stem cell-based regenerative medicine. Stem Cells Translational Medicine 2019;8:606-616.
