Figure 1From: Leptin promotes melanoma tumor growth in mice related to increasing circulating endothelial progenitor cells numbers and plasma NO productionCharacterization of endothelial progenitor cells (EPCs) by flowcytometry evaluation. First, cells were plotted in forward vs side scatter to gate the lymphocyte population selectively, where EPCs are usually found (a). For analysis of CD45dimCD34+KDR+ endothelial progenitor cells, CD45 was then plotted against the side scatter (b), followed by further analysis of the CD45dim population on coexpression of CD34/KDR (c).Back to article page
