Figure 2: Human pericytes home to perivascular locations. Confocal microscopy showed that GFP+ human pericytes (red), identified by anti-GFP immunostaining, can be located at the interstitial space where host CD31+ capillaries (green) reside (main, scale bar = 50 μm). Some GFP+ donor cells (inset, red arrows) are in close contact with mouse CD31+ endothelial cells (green). Dash line in the inset picture delineates a putative GFP+ cardiomyocyte (inset, scale bar = 10 μm).
