Figure 2

Surface marker expression profiles of three subcultures derived from Sca-1⁺-enriched populations analyzed by flow cytometry. All populations were analyzed for the expression of the stem/progenitor cell markers Sca-1 and c-kit, endothelial progenitor cell marker flk-1, endothelial cell specific marker CD31, hematopoietic progenitor marker CD34, and hematopoietic lineage marker CD45. Black line, non-stained cells; red line, corresponding antibody. (n = 3).
