Figure 3Transplanted EPCs home to the ischemic muscle. Representative photomicrographs of incorporated EPCs identified by double-fluorescence labeling in ischemic muscles. Transplanted human EPCs were stained using a biotinylated anti-human CD31 antibody (red fluorescence) in histological sections retrieved from ischemic muscles 4 days after injection. Mouse vasculature was identified by CD31 staining (green fluorescence) in the same tissue sections. Nuclei were stained with DAPI (blue labeling). Arrows indicate labeled EPCs. Scale bar: 50 μm.
