Megakaryocytes produce platelets
WebThey are produced by megakaryocytes residing in the bone marrow (BM), spleen, and lungs. Thrombopoietin (TPO) is the master cytokine regulator of megakaryopoiesis. 4 TPO maintains hematopoietic stem cell homeostasis and regulation of megakaryocyte and platelet number. 5 Once the cell has completed differentiation and become a mature megakaryocyte, it begins the process of producing platelets. The maturation process occurs via endomitotic synchronous replication whereby the cytoplasmic volume enlarges as the number of chromosomes multiplies without cellular division. The cell ceases its growth at 4N, 8N or 16N, becomes granular, and begins to produce platelets. Thrombopoietin plays a role in inducing the megakaryocyte to form s…
