Background:Researchers have explored the use of adipose-derived stem cells(ASCs)as a cellbased therapy to cover wounds in burn patients;however,underlying mechanistic aspects are not completely *** hypothesized that ASCs would improve post-burn wound healing after eschar excision and grafting by increasing wound blood flow via induction of angiogenesis-related ***:To test the hypothesis,we used an ovine burn model.A 5 cm^(2) full thickness burn wound was induced on each side of the *** 24 hours,the burned skin was excised and a 2 cm^(2) patch of autologous donor skin was *** wound sites were randomly allocated to either topical application of 7 million allogeneic ASCs or placebo treatment(phosphate-buffered saline[PBS]).Effects of ASCs culture media was also compared to those of *** healing was assessed at one and two weeks following the application of *** ASCs were isolated,cultured and characterized from non-injured healthy *** identity of the ASCs was confirmed by flow cytometry analysis,differentiation into multiple lineages and gene expression via real-time polymerase chain *** blood flow,epithelialization,graft size and take and the expression of vascular endothelial growth factor(VEGF)were determined via enzyme-linked immunosorbent assay and Western ***:Treatment with ASCs accelerated the patch graft growth compared to the control(p<0.05).Topical application of ASCs significantly increased wound blood flow(p<0.05).Expression of VEGF was significantly higher in the wounds treated with ASCs compared to control(p<0.05).Conclusions:ASCs accelerated grafted skin growth possibly by increasing the blood flow via angiogenesis induced by a VEGF-dependent pathway.
