Myofibroblasts were first identified in granulation tissue during skin wound healing. Typically, these cells are found in granulation tissue, scar tissue (fibrosis) and the stroma of tumours. They also line the gastrointestinal tract, wherein they regulate the shapes of crypts and villi. Myofibroblasts usually stain for the intermediate filament vimentin, which is a general mesenchymal marker, α-smooth muscle actin (human gene = ACTA2), and for palladin, which is a … WebDepending on the type of tissue to be remodeled, myofibroblast precursor cells are recruited from different sources; among these, locally residing fibroblasts seem to be the most …
WebThe role of α-smooth muscle actin in fibroblast-mediated matrix contraction and remodeling Cardiac myofibroblasts play an important role in myocardial remodeling. Although α-smooth muscle actin (α-SMA) expression is the hallmark of mature myofibroblasts, its role in regulating fibroblast function remains poorly understood.

WebJan 5, 2024 · Similar to organ fibrosis, myofibroblasts, a smooth-muscle-like contractile cell type that transformed from fibroblasts (FBs), are believed to be a key trigger for the implant-induced fibrotic reaction [ 3 – 6 ]. Therefore, approaches that suppress myofibroblasts may achieve desirable suppression effects in the fibrotic process.
