Chapter 2 – Megakaryocyte Development and Platelet Formation

WebMegakaryocytes (MKs) give rise to circulating platelets (thrombocytes) through terminal differentiation of MKs which release cytoplasmic fragments as circulating platelets. As MKs mature they undergo endoreduplication (polyploidisation) and expansion of cytoplasmic mass to cell sizes larger than 50-100 microns, and ploidy ranges up to 128 N. WebDespite an intense focus on platelet-tumor interactions (), it remains an understudied topic of research whether and how primary tumors affect platelet-producing MKs and thrombopoiesis.Tumor-derived interleukin-6 up-regulates hepatic thrombopoietin (TPO) production, leading to paraneoplastic thrombocytosis in ovarian cancer patients ().In … jim click for tucsonWebmegakaryocyte is released into the vasculature and begins to circulate.
