Circulating endothelial progenitor cells CD34+144+CD14- et CD34+VEGF-R2+CD14- have been shown to be inversely correlated to aortic aneurysm size. However reference values have not yet been determined. This study is aimed to determine reference values of CD34+144+CD14- et CD34+VEGF-R2+CD14- in healthy men and women blood donors.
At the time of blood donation, 10mL of blood will be used to calculate the concentration of circulating endothelial progenitor cells CD34+144+CD14- et CD34+VEGF-R2+CD14- , and the ratio of circulating endothelial progenitor cells CD34+144+CD14- et CD34+VEGF-R2+CD14- / all circulating endothelial progenitor cells in order to determine reference values.
