Alpha-smooth muscle actin (alpha-SMA) is the actin isoform that predominates within vascular smooth-muscle cells and plays an important role in fibrogenesis. Cultured myofibroblasts are characterized by stress fibers, containing -smooth muscle actin (-SMA) and by supermature focal adhesions (FAs), which are larger than FAs of -SMA-negative fibroblasts. We probed for stress fibers and focal adhesions (FAs) in TGF--treated murine fibroblasts and fibroblast migration was quantified rhPRG4. Activated fibroblasts and myofibroblasts Smooth muscle alpha-actin (SMA) is the definitive marker for the activated cardiac fibroblast population known as the myofibroblast ( Frangogiannis et al., 2000 ), but this actin isoform is also abundant in vascular smooth muscle cells ( Skalli et al., 1989 ). ACTA2 (actin alpha 2) is an actin protein with several aliases including alpha-actin, alpha-actin-2, aortic smooth muscle or alpha smooth muscle actin (-SMA, SMactin, alpha-SM-actin, ASMA). Expression of cancer-associated fibroblast markers in advanced colorectal cancer. The . Alpha smooth muscle actin (-SMA) was recently shown to be present in mouse subcutaneous tissue fibroblasts in the absence of tissue injury. Myoepithelial cells in breast and salivary gland are also stained. Fibroblasts, the most common cells in animal connective tissue, are spindle-shaped cells that produce components of the extracellular matrix (ECM) including collagens and glycosaminoglycans. Fibroblast Activating Protein 1 (FAP-1) is a marker for fibroblast activation and by many recognized as the main marker of CAFs. Myofibroblasts are thus regarded as the key activated fibrogenic cells for normal wound repair and abnormal tissue fibrogenesis, and -SMA is used as a marker for the fibrogenic activity of activated tissue fibrogenic cells [ 26, 34 ].
