in the present study , we examined the roles of the transforming growth factors tgf-alpha and tgf-beta in the induction and maintenance of ruffling in untransformed nrk cells and observed the following : tgf-alpha caused a transient epidermal growth factor ( egf ) -like response , which could be blocked by prior exposure of cells to egf or by antiserum directed against the cooh-terminus of tgf-alpha .
