Hemostasis is a process to stop bleeding that requires coordinated activities of vascular, platelet, and plasma factors. Under normal conditions, blood vessel injury will trigger endothelial cells to secrete factors that promote adhesion and activation of platelets. First, platelets bind to von Willebrand’s factor (vWF) secreted by endothelial cells through vWF receptors. Attached platelets then undergo degranulation and release factors such as serotonin, which causes vascular constriction. Activated platelets also release other mediators to attract additional platelets for aggregation at the injured sites.
