Effects of hASC^miR-301 on cardiac function after myocardial infarction (MI). (A) Cardiac functions were assessed using a Millar micro-tip 2 F pressure transducer at one week after MI (^# p < 0.05); (B) Fibrosis was detected by Masson’s trichrome staining from three rats per group. Scale bar = 5 mm (^# p < 0.05); (C) One week after the ASCs injection, PKH26-stained ASCs were detected in the ischemic myocardium. Scale bar = 200 μm; (D) Representative histological sections of ischemic myocardium stained with TUNEL assay at one week after MI. Quantitative analysis was performed for TUNEL (terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling) positive cells. Scale bar = 100 μm (** p < 0.01, ^# p < 0.05).
