NCIt definition : A family of growth factors that act as potent mitogens and are involved in the stimulation
of angiogenesis. There are four members of this family (platelet-derived growth factor
A, B, C and D) that are characterized by a core motif of eight cysteines. They bind
to their cognate receptor tyrosine kinases (platelet-derived growth factor receptor
family) as homodimers or heterodimers to stimulate signaling.;
Alternative definition : NCI-GLOSS: A family of molecules released from platelets (tiny pieces of cells that
are found in the blood and that help the blood clot). Forms of PDGF help to heal wounds
and to repair damage to blood vessel walls. They also help blood vessels grow.;
NCIt note : Vascular endothelial growth factors are considered a subfamily of the platelet-derived
growth factor family.;
