Figure 3. — mRNA expression of human UC-ECFCs at passage three. The endothelial cell genes, CD34, CD31, vWF, Tie-2, Flt-1, ec-NOS, KDR and VE-cadherin were all expressed by these cells, suggesting that these cells were EPCs. GAPDH was used as a positive control. UC-ECFCs, umbilical cord-derived endothelial colony-forming cells; EPC, endothelial progenitor cells; CD, cluster of differentiation; vWF, von Willebrand factor; Tie-2, epidermal growth factor homology domains-2; Flt-1, Fms related tyrosine kinase 1; ec-NOS, endothelial-nitric oxide synthase; KDR, kinase insert domain receptor; VE, vascular endothelial.
