NCIt related terms : Recombinant Platelet Factor 4;
NCIt definition : A recombinant form of the endogenous chemokine platelet factor 4 with potential antiangiogenesis
and antineoplastic activities. As a heparin-binding tetramer, iroplact inhibits growth
factor-stimulated endothelial cell proliferation, migration, and angiogenesis; it
has been shown that this agent inhibits fibroblast growth factor 2 (FGF2) angiogenic
activity downstream from the FGF2 receptor. Its activity is antagonized by heparin.
Recombinant platelet factor 4 may also directly inhibit the proliferation of some
tumor cell types.;
