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. WebAug 31, 2007 · Thus, the α-smooth muscle actin–expressing fibroblast, known as the myofibroblast, is shown to be the predominant source of type I collagen and fibrogenic/inflammatory cytokines in fibrotic lesions, as well as imparting altered mechanical properties to affected tissues ( 5, 10 ).

WebJul 1, 2013 · Myofibroblasts may be defined as cells that develop contractile force and stress fibers, de novo, and in vivo [1]. The most widely used and accessible marker of these cells is the de novo expression of α-smooth muscle actin (α-SMA), although this is not an absolute requirement for the identification of a cell as a myofibroblast.
