| Research Abstract |
Previous researches have demonstrated that adipose-derived stem cells (ASCs) possess the potential for not only tissue regeneration but also acceleration of wound healing with less scarring. However, the mechanisms of scar reduction remain still elusive. Therefore, we investigated the detail mechanism including angiogenesis and apoptotic effect of myofibroblasts/fibroblasts using murine diabetic would model. Results showed that epithelization rates, capillary density and the indices of myofibroblast apoptosis, and fibroblast apoptosis were all higher in ASCs group than in the control group mainly within 2 weeks after injury. These findings suggest that ASCs accelerate skin would healing at the same time as inducing apoptosis of both myofibroblasts and fibroblasts, thereby reducing scar formation in a diabetic murine model.
