Figure 1 Confirmation of endothelial progenitor cell (EPC) phenotype by immunohistochemistry. To validate the identity of EPC, we employed two methods as described in Methods. (A) Confirmation of adherent EPC by costaining with anti‐acetylated low‐density lipoprotein (LDL) and anti‐bandeiraea simplicifolia ‐1. (B) Endothelial marker expression of the colony‐forming unit counted by antibodies to Tie‐2 and CD‐31.
