Protein expression profiles of monocytic EPCs. (a) Flow cytometric analysis of monocytic EPCs derived from a healthy control. Cells were stained with anti-CD14 mAb plus mAb to CD34, VEGFR1, CD1a, CD83, or CD80, and analyzed by flow cytometry. (b) Immunohistochemical analysis of monocytic EPCs. Cells were stained with a mouse mAb to the endothelial marker, as indicated. Controls were incubated with an isotype-matched mouse mAb to an irrelevant antigen. Nuclei were counterstained with hematoxylin. Bars, 50 μm.
