Abstract excerpt
The growth of three non-tumorigenic human colonic adenoma cell lines, designated AA/C1, RG/C2 and RR/C1, was inhibited by low concentrations of transforming growth factor beta (TGF-beta) (0.05-0.5 ng ml-1). However, the growth of five human colon cancer cell lines under identical conditions was resistant to high concentrations of TGF-beta (2-10 ng ml-1). This is the first report of well-characterized premalignant...
