Inflammatory and Anti-Inflammatory Equilibrium, Proliferative and Antiproliferative Balance: The Role of Cytokines in Multiple Myeloma. Thrombopoietin (TPO) was the last major hematopoietic growth factor to be identified, purified and cloned. The concept of a thrombopoietin had first entered the medical literature in 1958 when Kelemen proposed that a hematopoietic growth factor existed that regulated platelet production just as erythropoietin-regulated red cell production [] TPO is a lineage-specific growth factor produced in the liver, kidney and skeletal muscle. It stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals through the c-mpl receptor, and acts as an important regulator of circulating platelets In addition, HIF-1 is also vital for the development of hematopoietic stem cells (HSCs). In a previous study we found that thrombopoietin (TPO), an important and non-redundant cytokine for HSC maintenance and expansion, induces HIF-1α expression in HSCs by enhancing the stability of HIF-1α under normoxic conditions

Thrombopoietin (TPO) receptor agonists represent a new approach for the treatment of thrombocytopenia, which may develop as a consequence of immune thrombocytopenia, chemotherapy treatment, chronic hepatitis C infection, or myelodysplastic syndromes. There are concerns that use of certain growth factors can hasten disease progression in some types of hematologic malignancies and solid tumors Eltrombopag is a thrombopoietin receptor agonist that binds to and activates the thrombopoietin (TPO) receptor, thereby increasing platelet production. Indications and dose Chronic immune (idiopathic) thrombocytopenic purpura in patients refractory to other treatments (such as corticosteroids or immunoglobulins) (under expert supervision

Maintenance of hematopoietic stem cells (HSCs) depends on interaction with their niche. Here we show that the long-term (LT)-HSCs expressing the thrombopoietin (THPO) receptor, MPL, are a quiescent population in adult bone marrow (BM) and are closely associated with THPO-producing osteoblastic cells.

Spin down and send 1 mL of serum frozen in a plastic vial Central nervous and hematopoietic systems share developmental features. We report that thrombopoietin (TPO), a stimulator of platelet formation, acts in the brain as a counterpart of erythropoietin (EPO), a hematopoietic growth factor with neuroprotective properties. TPO is most prominent in postnatal brain, whereas EPO is abundant in embryonic.

Thrombopoietin: 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. Thrombopoietin (TPO) is a hormone produced by the liver that regulates platelet production by binding to and activating TPO receptors that are present on the surface of megakaryocytes. This induces a series of signaling cascades, leading to increased platelet production . As a result, TPO levels typically decrease as liver disease progresses Thrombopoietin, the ligand for the c-mpl receptors, is a primaryregulator of platelet production in vivo. Since thrombopoietin was cloned,[7-11]two recombinant forms have been evaluated in clinical trials Eltrombopag is a drug designed to mimic the protein thrombopoietin, which causes the body to make more platelets. Eltrombopag has been able to increase platelet counts in healthy volunteers and in patients with chronic ITP (a disease where patients destroy their own platelets very rapidly and thus develop thrombocytopenia), but researchers do not know if the drug can increase platelet counts in patients with MDS
