Figure 1 Circulating endothelial progenitor cells (EPCs) and circulating progenitor cells (CPCs) were identified by flow cytometry with low cytoplasmic granularity and with the expression of cell surface antigens, such as CD34 and VEGF-R2 (KDR). (A) Representative flow cytometry analysis of a blood sample from a patient with high EPC count. (B) The number of EPCs from peripheral blood in the four groups of subjects. Mean values ± SE. CTRL = control subjects; NS = not statistacally significant. *p < 0.05.
