摘要: Publisher Summary This chapter focuses on the mechanisms of action transforming growth factor- β (TGF- ) and related factors, in particular their interaction with specific receptors binding proteins. TGF- was initially purified from human platelets as a 25-kDa homodimeric peptide using ability factor to confer morphological transformation anchorage-independent normal rat kidney (NRK) fibroblasts an assay. The biological effects that are mediated by include regulation cell proliferation, differentiation, adhesion, migration; stimulation extracellular matrix (ECM) deposition; modulation many inflammatory immune responses. has been proposed have important vivo physiological roles tissue recycling, wound repair, morphogenesis during embryogenic development. Three distinct isoforms identified mammals; denoted TGF 1, 2, 3, they exert similar, but not identical, activities vitro well vivo. cellular is through surface receptors. carefully controlled. s secreted cells latent forms activated under certain conditions.
