Abstract (original English)

Introduction Diabetes mellitus remains a significant public health problem, consuming over $400 billion every year. While Diabetes itself can be controlled effectively, impaired wound healing still occurs frequently in diabetic patients. Adipose-derived mesenchymal stem cells (ASCs) provide an especially appealing source for diabetic wound cell therapy. With autologous approaches, the functionality of ASCs largely underlie patient-dependent factors. Diabetes is a significant diminishing factor of MSC functionality. Here, we explore a novel strategy to enhance diabetic ASC functionality through deferoxamine (DFO) preconditioning. Material and methods Human diabetic ASCs have been preconditioned with 150 µM and 300 µM DFO in vitro and analyzed for regenerative cytokine expression. Murine diabetic ASCs have been preconditioned with 150 µM DFO examined for their in vitro and in vivo vasculogenic capacity in Matrigel assays. Additionally, a diabetic murine wound healing model has been performed to assess the regenerative capacity of preconditioned cells. Results DFO preconditioning enhances the VEGF expression of human diabetic ASCs through hypoxia-inducible factor upregulation. The use of 150 µM of DFO was an optimal concentration to induce regenerative effects. The vasculogenic potential of preconditioned diabetic ASCs is significantly greater in vitro and in vivo. The enhanced re
