to examine the mechanisms by which transforming growth factors ( tgfs ) regulate the proliferation of eukaryotic cells , five cell lines , from different species and tissues , were treated with three agents that inhibit dna synthesis and proliferation : bsc-1 cell-derived growth inhibitor ( gi/tgf-beta ) , platelet-derived transforming growth factor-beta ( tgf-beta ) , and 12-o-tetradecanoylphorbol-13-acetate .
