Using the pig model, intracoronary delivery of mesenchymal stem cells containing fluorescent and iron nanoparticles following myocardial infarction and reperfusion results in substantially more cells deposited in the infarcted and border zones. The total numbers of cells for each section are shown as gray bars. No cells were retrieved in non-infarct tissue (control). The actual number is the cell number retrieved from the obtained samples and the theoretical scaled number was extrapolated to reflect the total border zone and infarcted myocardial volume. Approximately 65% of the delivered cells were recovered immediately after delivery. Error bars indicate standard deviation.
