What do platelets function to?
The function of the platelets is to clot blood.There for it stops blood from flowing if a body part is cut. maintainence of haemostasis.(process which causes the bleeding to stop.) platelets secrete platelet-derived growth factor(PDGF)
17-78 PDGF is encoded by a gene that can cause cancer when expressed inappropriately Why then do cancers not arise at wounds when PDGF is released from platelets?
The on-demand, limited release of PDGF at a wound site triggers cell division of neighboring cells for a limited amount of time, until the PDGF is degraded. This is different from the continuous release of PDGF from mutant cells, where PDGF is made in an uncontrolled way at high levels. Moreover, the mutant cells that make PDGF often inappropriately express their own PDGF receptor, so that they can stimulate their own proliferation, thereby promoting the development of cancer
