Abstract Type 2 diabetes mellitus (T2DM) is a metabolic disease caused by insulin resistance that leads to changes in glucose metabolism. Importantly, both insulin resistance and hyperglycemia are present in T2DM patients as a hallmarks of metabolic syndrome. They negatively affect functions of many cells, for example endothelial cells. Endothelial progenitor cells (EPC) is a population of mononuclear cells that expresses endothelial and progenitor markers. EPC are also characterized by ability to form tubes on matrigel, outgrowth into mature endothelial cells, produce proangiogenic factors or take part in the blood vessels formation. Upon injury endothelial progenitor cells are mobilized from bone marrow, home to injured site and take part in vessels formation. It was shown however, that functions of EPC in T2DM patients are impaired. In this review we focused on the T2DM and its detrimental effects on EPC biology. taking also into account the beneficiary role of anti-diabetic drugs. Decreased number and impaired functions of EPC in T2DM patients might lead to increased frequency of cardiovascular incidents and development of micro- or macroangiopathies.
