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)
PDGF
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
Platelet-derived growth factor (PDGF) is a chemical that stimulates mitosis in healing wounds. It is released by blood platelets and other cells at the wound site to promote cell division, proliferation, and tissue repair.

Yes, T cells secrete cytokines as part of their immune response.
A platelet in Biology is part of one's blood system. Platelets are utilized in order to essentially repair damage to the vascular system or any other damaged part.
