Abstract
Transforming growth factor-beta (TGF-beta) is a homodimeric polypeptide of 25 kDa, which regulates cell growth and differentiation and influences extracellular matrix metabolism. Using immunochemical techniques, we identified TGF-beta in the loops of Henle and the collecting and Bellini ducts of rat kidney and in the loops of Henle of chicken kidney. Furthermore, we detected two TGF-beta-immunoreactive proteins on kidney blots of the rat of 12.5 and 47 kDa, and three on chicken kidney blots of 12.5, 34, and 47 kDa. We suggest that the precursor forms of rat and chicken TGF-beta 2 or beta 3, chicken TGF-beta 4, and the mature form of all of them are expressed in the collecting and Bellini ducts of rat kidney and the loops of Henle of rat and chicken kidney.Entities:
