Figure 3: Direct fluorescent staining of endothelial progenitor cells from fresh mononuclear cells. Using an inverted fluorescence microscope, cells were examined for isolectin B4 (green, Figure 3-a; 3-c) and dil-ac-LDL uptake (red, Figure 3-b; 3-d). EPCs adherent cells were considered for analysis if there were positive for isolectin B4 staining and dil-ac-LDL uptake (yellow, Figure 3-e).
