如果是做血管再生实验,一般是用ECFC,也称作late outgrowth endothelial progenitor cells(EPCs) 或是blood-outgrowth endothelial cells(BOECs),与early out growth EPC(CD14+CD45+,来源于髓系/单核细胞系,通过旁分泌方式参与血管再生)相区别。具体步骤可参考文献"Strikingly different angiogenic properties of endothelial progenitor cell subpopulations: insights from a novel human angiogenesis assay."和"Redefining endothelial progenitor cells via clonal analysis and hematopoietic stem/progenitor cell principals".
