Abstract
In vitro, transforming growth factor type betal triggers normal cells to induce apoptosis in transformed cells. We show that in the absence of exogenous transforming growth factor type betal, induction of apoptosis of transformed cells in coculture with normal cells is dependent on the number of transformed cells per assay and is abrogated by antibodies against TGF-beta 1. Therefore, transforming growth factor type betal produced by transformed cells seems to be responsible for triggering a mechanism that leads to the induction of their apoptosis. This mechanism may be crucial for the control of carcinogenesis in vivo.
