Transforming growth factor-beta (TGF-beta) regulates proliferation, morphogenesis, and functional differentiation in the mammary gland and plays complex roles in mammary tumorigenesis. Here we show that the signaling mediators Smad1-Smad5 are expressed at all stages of mammary gland development. To begin to investigate which Smads mediate which TGF-beta… CONTINUE READING
