Abstract
Abstract Novel polypeptide compositions are provided which inhibit human tumor cell growth, which may or may not stimulate autophosphorylation of pp60 src and induce the release of a 52kDal polypeptide from neoplastic cells. Individual polypeptides may be isolated from mammalian blood platelets by selected extraction and purification procedures, may be synthesized or produced by hybrid DNA technology.
