MSH: A humoral factor that stimulates the production of thrombocytes (BLOOD PLATELETS). Thrombopoietin stimulates the proliferation of bone marrow MEGAKARYOCYTES and their release of blood platelets. The process is called THROMBOPOIESIS.,NCI: A substance made by the body that helps make blood cells, especially platelets. A form of TPO made in the laboratory is called recombinant human TPO and rHu TPO. TPO is being studied as a way to increase the number of platelets in cancer patients receiving chemotherapy.,CHV: a kind of hormone,CHV: a kind of hormone,NCI: Thrombopoietin is a lineage-restricted, glycoprotein growth factor ligand for the MPL receptor with selective action on megakaryopoiesis and platelet production. THPO has little direct effect on erythroid progenitor cells but may enhance erythropoiesis indirectly by preventing early erythroid progenitor cells from undergoing apoptotic cell death. (from OMIM 600044 and NCI)
