Myofibroblast phenotype
WebIntroduction to the myofibroblastic phenotype. Myofibroblasts were first described in healing skin wounds, where it was hypothesized that they were responsible for the phenomenon of wound contraction. 1 Since then, cells morphologically similar to myofibroblasts have been described in many tissues, predominantly in pathological states … There are many possible ways of myofibroblast development: 1. Partial smooth muscle differentiation of a fibroblastic cell 2. Activation of a stellate cell (e.g. hepatic Ito cells or pancreatic stellate cells). 3. Loss of contractile phenotype (or acquisition of "synthetic phenotype") of a smooth muscle cell.

WebMar 17, 2016 · Using explanted primary cardiac fibroblasts in gain- and loss-of-function studies, we found that scleraxis critically controls cardiac fibroblast/myofibroblast phenotype by direct transcriptional regulation of myriad genes that effectively define these cells, including extracellular matrix components and α-smooth muscle actin. WebWe hypothesized that YAP1 regulates the differentiation of dermal fibroblasts into highly contractile myofibroblasts and that YAP1 governs the maintenance of a myofibroblast phenotype in… Meer weergeven Dupuytren disease is a fibrotic disorder characterized by contraction of myofibroblast-rich cords and nodules in the hands.
WebAug 28, 2024 · For example, resident fibroblast in the liver and pancreas, known as quiescent hepatic stellate cells (HSCs) and pancreatic stellate cells (PSCs), can acquire a myofibroblast-like phenotype, including α-smooth muscle actin (α-SMA) expression (which considered as CAFs in liver and pancreatic cancers, respectively) upon TGF-β and PDGF ... WebHere, they acquired a myofibroblast phenotype and when exposed to appropriate chemical stimulus, developed tension and cell shortening, similar to those of striated and smooth muscle cells. Myofibroblasts contained a molecular motor—the non-muscle myosin type IIA (NMMIIA) whose crossbridge (CB) kinetics are dramatically slow compared with ...
