Expression of EPC surface markers in chicken EPCs. Expression of the EPC-specific markers CD133, CD34 and VEGFR-2 were examined by immunofluorescent labeling in chicken EPCs. CD133 marks both hematopoietic stem cells and EPCs. Its expression is gradually lost upon differentiation of EPCs into mature cells. A,D, and G. Phase contrast; B. VEGFR-2+; E. CD133+; H. CD34; C,F, and I. Merged.
