Gene expression analysis of cluster of differentiation 31 (cd31), platelet-derived growth factor receptor beta (pdgfrβ), snail (snai1), zinc finger E-box-binding homeobox 2 (zeb2), smooth muscle actin alpha 2 (acta2), fibronectin (fn), fibroblast-specific protein 1 (fsp1) and vimentin in the hearts of Sham and HFpEF mice. n = 7–11/group. Statistical analysis by 2-tailed Student t test for normally distributed data or Mann-Whitney U for those variables that were non-normally distributed.
