Phenotypic characterization and functional analysis of hCB-EPCs.

<p>(A) Cultured hCB-EPCs grown in 5% FBS or 0.5 mg/ml UCE medium showing endothelial-specific marker staining for PECAM and vWF. (B) FACS analysis of cultured hCB-EPCs for the expression of the endothelial markers CD34, CD31, and CD105; the mesenchymal marker CD90; and the hematopoietic maker CD45. (C) Capillary-like structures formed by hCB-EPCs in 5% FBS or 0.5 mg/ml UCE on Matrigel. (D) Acetylated LDL uptake and DAPI staining.
