Thrombopoiesis begins in the bone marrow milieu with the differentiation of pleuripotent stem cell to megakaryocytes. Several key regulators (TPO, interleukins, B12, folate, NF-κB) are involved in platelet formation. Platelets have several destinations in the peripheral circulation including self-regulated apoptosis, consumption in response to injury, splenic sequestration, and platelet destruction. Causes of decreased platelet production (yellow box) and increased peripheral destruction (red box) are shown. Abbreviations: MDS (myelodysplastic syndrome), TPO (thrombopoietin), IL (interleukin), SCF (stem cell factor), NF-κB (nuclear factor kappa B), DIC (disseminated intravascular coagulation), HELLP (hemolysis, elevated liver enzymes and low platelets).
