Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.n this condition, your bone marrow makes too many platelets. People with thrombocythemia may have platelet counts that exceed 1 million. Symptoms can include blood clots that form and block blood supply to the brain or the heart. The cause of thrombocythemia is unknown.
A megakaryocyte (mega- + karyo- + -cyte, large-nucleus cell) is a large bone marrow cell with a lobulated nucleus responsible for the production of blood thrombocytes (platelets), which are necessary for normal blood clotting.latelets are held within these internal membranes within the cytoplasm of megakaryocytes. There are two proposed mechanisms for platelet release. In one scenario, these proto-platelet processes break up explosively to become platelets. Alternatively, the cell may form platelet ribbons into blood vessels.
