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 1, 2024 · The minimal requirements to define a non-muscle cell as myofibroblast are (a) association with fibrillar collagen, (b) (neo-) formation of actin-myosin bundles (called stress fibers in vitro ), and (c) the ability to exert contractile force [ 70 ].
