hucMSC‐exosomes attenuated cells apoptosis in CVB3‐induced myocarditis in vitro. A, Detection the cell apoptosis using annexin V and PI assay. B, The quantitation of annexin V and PI assay. C, Western blot analysis. D, The quantitation of Western blot. Data were expressed as mean ± SD. n = 6. NS means no significance differences. *P < 0.05, **P < 0.01, ***P < 0.001 indicate significant differences when compared with control (0 MOI CVB3) or hucMSC‐exosome treatment (0 or 50 μg/mL), respectively
