The regulated release of proteins by a platelet or group of platelets. The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet. The regulated release of serotonin by a platelet or group of platelets. The directed movement of substances into, out of or within a cell by a cellular process that begins with the formation of membrane-bounded vesicles in which the transported substances are enclosed or located in the vesicle membrane. Vesicles are then targeted to, and fuse with, an acceptor membrane. A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell. This is the process whereby most molecules are secreted from eukaryotic cells. The regulated release of histamine by a platelet or group of platelets. The controlled release of a substance by a cell.
