Aggregation of CD11b + cells at the site of injury after myocardial infarction and target of MSN-NGR1-CD11b antibody nanoparticles to the MI site. Single nucleated cells isolated from the peripheral blood of Zsgreen mice (A). Isolated cells from the peripheral blood of Zsgreen mice expressing CD11b (B). Some CD11b + cells at the infarcted site were overlapped with intravenously injected Zsgreen-positive cells (arrowhead, C). Arrows showing an absence of injected Zsgreen-positive cells. Scale bar: 50 μm. In vivo imaging photograph of MSN-NGR1 nanoparticles after tail vein injection (D). The fluorescence intensity of in vivo imaging photographs (E).
