Figure 3 Tracking of In-111–Labeled Endothelial Progenitor Cells in the Rat Heart
After experimental myocardial infarction, 106 indium (In)-111–labeled cells were injected intramyocardially (left) or intravenously (right). Shown are planar scintigraphic images of the whole animal, along with magnification of the cardiac area. Significant cardiac retention of cells in the heart is only identified after intramyocardial injection (arrow).
