The concept of EPC-capture stents. Numerous studies have shown that circulating EPCs contribute to the repair of the endothelium after injury, most likely by repopulating the site of stent implantation. The number of circulating EPCs is considered a marker of the turnover of the endothelium, as well as a promising marker of the cardiovascular risk. EPCs can be identified by the presence of surface markers - CD34, CD133 - or vascular endothelial growth factor type 2 receptor (VEGFR2) which can be identified using labeled monoclonal antibodies. Since EPCs represent a pool of cells which contribute to the endothelial repair after vascular injury, the increased homing and retention of these cells at the site of stent implantation may increase and speed up the process of endothelisation.
