Specific signals involved in the long-term maintenance of radiation-induced fibrogenic differentiation: a role for CCN2 and low concentration of TGF-beta1.


The fibrogenic differentiation of resident mesenchymal cells is a key parameter in the pathogenesis of radiation fibrosis and is triggered by the profibrotic growth factors transforming growth factor (TGF)-beta1 and CCN2. TGF-beta1 is considered the primary inducer of fibrogenic differentiation and is thought to control its long-term maintenance, whereas… (More)
