<unk>  is the formation of platelets in the Bone marrow. Thrombopoietin is the main regulator of<unk> . Thrombopoietin affects most aspects of the production of platelets. This includes self-renewal and expansion of hematopoietic stem cells, stimulating the increase of megakaryocyte progenitor cells, and supporting these cells so they mature to become platelet-producing cells. The process of<unk>  is caused by the breakdown of proplatelets (mature megakaryocyte membrane pseudopodial projections). During the process almost all of the membranes, organelles, granules, and soluble macromolecules in the cytoplasm are being consumed. Apoptosis also plays a role in the final stages of<unk>  by letting proplatelet processes to occur from the cytoskeleton of actin.
