Background
Thrombopoietin (TPO) is a glycoprotein that produced by the liver, kidney, marrow stroma and several other tissues. The TPO level in the blood is mostly negatively correlated with the abundance of platelets and bone marrow megakaryocytes, although multiple states of inflammation or infection, liver failure, and hematological disturbances are associated with unexpectedly high or low circulating levels of the hormone.
Synonyms
Thrombopoietin, C-mpl ligand , ML, Megakaryocyte colony-stimulating factor, Megakaryocyte growth and development factor , MGDF, Myeloproliferative leukemia virus oncogene ligand
