Autologous Endothelial Progenitor Cells Treatment of Diabetic Foot

The vascular pathologic basis of diabetic foot include arterial obstruction and micro-circulation defects.The latest technology of arterial reconstruction can only rebuild blood flow of anterior,posterior tibial artery and peroneal artery.Endothelial progenitor cells have been proved to integrate into damaged vascular endothelium and improve vasculogenesis in vitro and in animal experiment.Therefore endothelial progenitor cells are supposed to improve the micro-circulation status of diabetic foot patients.In this trial,the investigators recuit diabetic foot patients with infrapopliteal arterial obstructive disease,treat them with autologous endothelial progenitor cells after intraluminal intervention,and observe the therapeutic efficacy comparing to single intraluminal intervention.
