Myofibroblasts upregulate the expression of fibronectin, collagens, and hyaluronic acid during and after their differentiation from fibroblasts. Among these, the EDA isoform of fibronectin (EDA-FN), and collagen type I (COL1A1/COL1A2) are typical markers of myofibroblast-dependent synthesis of pro-fibrotic extracellular matrix.
Histopathologically, FMTs consist of neoplastic connective tissue cells which have differented into cells that have microscopic appearances resembling fibroblasts and/or myofibroblasts. The fibroblastic cells are characterized as spindle-shaped cells with inconspicuous nucleoli that express vimentin , an intracellular protein typically found in ...
The normal fibroblast cells receive a hormone signal from nearby cancer cells, indicating that it must become activated, and is thus classed as a CAF. [2] It is unclear why normal fibroblasts transition into CAFs but it has been found that by adding transforming growth factor-β to fibroblasts in culture they start to display features of CAFs. [26]
A fibroblast is a type of biological cell typically with a spindle shape [1] that synthesizes the extracellular matrix and collagen, [2] produces the structural framework for animal tissues, and plays a critical role in wound healing. [3]
IMT lesions typically consist of, and are defined by, myofibrolastic spindle cells, [7] i.e. specialized cells that are longer than wide, have a microscopic appearance that merges the appearances of fibroblasts and smooth muscle cells (see myofibroblast), occur in normal as well as tumor tissues, and in normal tissues are commonly designated ...

Fibroblast growth factor 2 (FGF-2), also known as basic fibroblast growth factor (bFGF) and FGF-β, is a growth factor and signaling protein encoded by the FGF2 gene. [ 5 ] [ 6 ] It binds to and exerts effects via specific fibroblast growth factor receptor (FGFR) proteins , themselves a family of closely related molecules.
The primary mouse embryonic fibroblast cells were transferred (the "T") every 3 days (the first "3"), and inoculated at the rigid density of 3 × 10 5 cells per 20 cm 2 dish (the second "3") continuously. [2] The spontaneously immortalized cells with stable growth rate were established after 20 to 30 generations in culture, and then named '3T3 ...
