In vivo engraftment and functional capacity of CD14⁺/VEGFR-2⁺ and CD14⁺/VEGFR-2^- cells. (A) Transcription of human endothelial-specific genes in the mouse artery. Human CD31 and e-NOS were detected in balloon-injured mouse femoral arteries that received human CD14⁺/VEGFR-2⁺cells but not in mice that underwent sham transplantation or that received CD14⁺/VEGFR-2 cells. ABL was used as the housekeeping gene.
