Transforming growth factor beta 1 stimulates the production of basic fibroblast growth factor binding proteoglycans in Balb/c3T3 cells.

Basic fibroblast growth factor (bFGF) binds to cell surface receptors and to heparin sulfate proteoglycans. Heparan sulfate binding may limit bFGF degradation and be an obligatory step for bFGF cell interaction. Transforming growth factor-beta 1 (TGF-beta 1) is a potent regulator of proteoglycan production and composition. The possibility that TGF-beta 1… CONTINUE READING
