Cytokine control of megakaryopoiesis
WebMegakaryopoiesis is regulated at multiple stages via cytokines (blue). In the classical pathway, megakaryopoiesis begins with thrombopoietin signaling via its receptor c-mpl (red), which is expressed throughout … Webcytokine control of megakaryopoiesis have given many insights into the process that ultimately reg-ulates platelet production [1-5]. In addition, flow cytometry has been found to be a sensitive and efficient method for the analysis of MKs and their ploidy in normal and disease states [6, 7]. As platelet precursors, MKs acquire many

WebFeb 22, 2024 · The first possibility is that infection induces a cytokine storm (including thrombopoietin and interleukin-3, -6, -9, and -11) stimulating megakaryopoiesis and/or thrombopoiesis. The second is that endothelial injury may occur, leading to the release of von Willebrand factor (vWF), which may interact with megakaryocytes via GPIb/vWF. WebOverview of Megakaryopoiesis. Megakaryocytes (MKs), the precursors of platelets, are derived from pluripotent hematopoietic stem cells (HSCs). Every day approximately 1×10 11 platelets are produced by the cytoplasmic fragmentation of MKs, a level of production that can increase 10- to 20- fold in times of demand and an additional 5- to 10- fold under the …
