WebThrombopoietin ( TPO) is a 332 amino acid glycoprotein made primarily in the liver that stimulates the formation of megakaryocytes from CFU-Meg (colony forming unit, megakaryocyte). TPO binds to receptors that dimerize and activate cytoplasmic kinases. These kinases phosphorylate STAT-1, 3, and 5 and CREB. sigma charlestown inWebJul 19, 2024 · Thrombopoietin (TPO) is the physiologically relevant regulator of platelet production.
