Effect of transplantation of CSCs on LV function. Serial echocardiographic studies were performed at baseline (BSL, 4 days prior to coronary occlusion/reperfusion), 48 h after CSC treatment (4 days after reperfusion), and 35 days after CSC transplantation (37 days after reperfusion and 4 days prior to euthanasia). i.m., intramyocardial injection; i.c., intracoronary infusion. Data are mean ± SEM
