BMSC-Exo-125b restored the cardiac function of myocardial ischemia reperfusion injury (I/R) rats. a Hemodynamic test of I/R rats. b HE staining was performed to detect the pathological changes of myocardium in I/R rats (× 400). c Triphenyltetrazolium chloride (TTC) assay was used to evaluate the infarct size in I/R rats. d qRT-PCR was used to examine the relative mRNA expression of SIRT7 in myocardium tissues. e Relative density of SIRT7 was detected by immunohistochemistry in myocardium tissues (× 400). f Western blot was used to examine the relative protein expression of SIRT7 in myocardium tissues
