Stimulation of normal human fibroblast collagen production and processing by transforming growth factor-beta.
Transforming growth factor-beta (TGF beta) a growth factor with diverse effects on cellular growth and metabolism, caused dramatic stimulation of total protein and collagen synthesis by confluent normal human dermal fibroblasts in culture in a dose-dependent manner. Gel electrophoresis of the newly synthesized macromolecules from the culture media of TGF beta treated cultures demonstrated accelerated procollagen processing. These results indicate that TGF beta is capable of qualitatively and quantitatively influencing the biosynthesis of matrix molecules by fibroblasts, and raise the possibility that TGF may play a role in the development of normal and pathologic fibrogenesis.
