BM-EPC culture and identification.

<p><b>A</b>. Photomicrographs showing that after 5 days of culturing, BM-EPC isolated from rat bone marrow, displayed spindle-like attached cells and formed colonies (<b>a</b>), Bar = 140 µm. Higher magnification showed that these cells performed endothelial cell morphology (<b>b</b>), Bar = 140 µm. <b>B</b>. Putative BM-EPCs were stem cell marker CD34⁺ (red color) and were able to take in Ulex europeus agglutinin-5 (green color. <b>c</b>). They also were DiI-acLDL⁺(red color) and fluorescein isothiocyanate-Ulex europeus agglutinin-1⁺(green color), which were (d) co-localized in >95% cells, Bar = 100 µm.
