WebbThe production of Megakaryocytes and platelets is regulated by a hormone called Thrombopoietin, which is also called megakaryocyte growth and development factor encoded by THPO gene. The process of formation of Platelets is called Thrombopoiesis which occur in the bone marrow. A single megakaryocyte can produce around 2,000 … WebbThe production of platelets by megakaryocytes requires an intricate series of remodeling events that result in the release of thousands of platelets from a single megakaryocyte. Abnormalities in this process can result in clinically significant disorders. Thrombocytopenia (platelet counts less than 150,000/microl) can lead to inadequate …
