Endothelial progenitors are a population of cells with the inherent capacity to differentiate into mature endothelial cells and proangiogenic paracrine action. These characteristics have led to extensive studies being performed and tested in the treatment of tissue ischemia. The natural course of diabetes mellitus (DM) results in multiple areas of vascular damage. Thus endothelial progenitor cells'(EPCs) beneficial potential is particularly desirable in diabetic patients. In this review, we summarize contemporary knowledge of EPC biology in DM. It has been shown that EPC functions are considerably impaired by DM. The presence of peripheral arterial disease (PAD) seems to further exacerbate the deficiencies of EPCs. However, studies examining EPC counts in PAD and DM observed disparate results, which can be due to a lack of consensus on precise EPC immunotype used in the different studies. Nevertheless, the results of EPC-based autologous cell therapy (ACT) are promising. In addition, EPCs have been shown to bean independent predictor of cardiovascular risk and diabetic foot ulcer healing.

The aim of this study was to compare the serum levels of the anti-angiogenic factor endostatin (S-endostatin) as a potential marker of vasculogenesis after autologous cell therapy (ACT) versus percutaneous transluminal angioplasty (PTA) in diabetic patients with critical limb ischemia (CLI). A total of 25 diabetic patients with CLI treated in our foot clinic during the period 2008-2014 with ACT generating potential vasculogenesis were consecutively included in the study; 14 diabetic patients with CLI who underwent PTA during the same period were included in a control group in which no vasculogenesis had occurred. S-endostatin was measured before revascularization and at 1, 3, and 6 months after the procedure. The effect of ACT and PTA on tissue ischemia was confirmed by transcutaneous oxygen pressure (TcPO2) measurement at the same intervals. While S-endostatin levels increased significantly at 1 and 3 months after ACT (both P < 0.001), no significant change of S-endostatin after PTA was observed. Elevation of S-endostatin levels significantly correlated with an increase in TcPO2 at 1 month after ACT ( r = 0.557; P < 0.001). Our study showed that endostatin might be a potential marker of vasculogenesis because of its significant increase after ACT in diabetic patients with CLI in contrast to those undergoing PTA. This increase may be a sign of a protective feedback mechanism of this anti-angiogenic factor.
