In other three groups, the left coronary artery was ligated to establish myocardial infarction models. Following 15 minutes of coronary artery deligation, the chest was opened. Rats in the cotransplantation group were treated with 250 μL (1×1010/L) BMSCs suspension + 8 mg/L Salvianolic acid B-treated EPC suspension 250 μL (1×108/L) in five points of the myocardium surrounding the deligation region. Rats in the BMSCs group received 500 μL BMSCs suspension. Rats in the model group were injected with an equal volume of cell medium.
