Abstract:
Because poor skin wound healing associated with diabetes is thought to be partly a result from impaired angiogenesis, treatments that improve angiogenesis could have important clinical applications. We herein report the effects of novel developed material, collagen-poly glycolic acid fiber hybrid matrix, being used together with basic fibroblast growth factor to promote wound healing of full-thickness skin defects on the back of type 2 diabetic Lepr(db) mice. Our data indicates that this therapeutic approach markedly promotes angiogenesis and granulation tissue formation in comparison with other conditions 14 days after wounding.
