Dynamic Tracking of Injected Mesenchymal Stem Cells after Myocardial Infarction in Rats: A Serial 7T MRI Study

Figure 2

MRI assessment of cardiac morphology and function. (a) The typical course after myocardial infarction including progressive scar thinning, left ventricular dilatation, and functional deterioration was observed in both groups at baseline. However, serial cine-MRI studies between baseline and 4 weeks showed that MSCs injection resulted in moderated LV dilatation and dysfunction compared with controls (b–c). for MSCs group and for control group at each time point. versus baseline; versus control.
