Effects of 2,3-bis(4-hydroxyphenyl)-propionitrile (DPN) and N-[N-(3,5-difluorophenacetyl)-l-alanyl]-s-phenylglycine t-butyl ester (DAPT) on cardiac fibrosis after MI. a Haematoxylin and eosin (H&E), Masson’s trichrome and Sirius Red staining of transverse frozen tissue sections from each group 28 days after MI. b Statistical analysis of H&E staining data (the average thickness of the left ventricles). c Statistical analysis of Masson’s trichrome and Sirius Red staining (scar size). The values are the means ± SEM. n = 6; *P < 0.05, **P < 0.01 and ***P < 0.001
