Dictionary » P » Platelet



(Science: haematology) A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels.

platelet _ granules contain lysosomal enzymes, dense granules contain adp (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation.

Synonym: thrombocytes.
