VIM and Myocardial fibrosis: Fibroblasts may respond to mechanical loading through a switch to a myofibroblastic phenotype in which they express α‐SMA.32 The transformation of myofibroblasts from CFs is a critical event in the initiation of myocardial fibrosis.33 The total cells were identified using DAPI and vimentin staining to detect the effects of TGD on TGF‐β1–induced myofibroblast transformation.
