Erythropoietin (/ ɪ ˌ r ɪ θ r oʊ ˈ p ɔɪ. ɪ t ɪ n,-r ə-,-p ɔɪ ˈ ɛ t ɪ n,-ˈ iː t ɪ n /; [1] [2] [3] EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow.
[5] [6] They work similar to naturally occurring erythropoietin. [1] They were first approved for medical use in the United States in 1989. [5] It is on the World Health Organization's List of Essential Medicines. [7] Commercially available agents include epoetin alfa and darbepoetin alfa, and biosimilars.
Loss of function of the erythropoietin receptor or JAK2 in mice cells causes failure in erythropoiesis, so production of red blood cells in embryos and growth is disrupted. If there is no systemic feedback inhibition, for example, the diminishment or absence of suppressors of cytokine signaling proteins, giantism may result as shown in mice models.
Erythropoietin is a sialoglycoprotein hormone produced by peritubular cells of kidney. Granulocyte -macrophage colony-stimulating factor and granulocyte CSF are given to stimulate white blood cell formation in cancer patients who are receiving chemotherapy , which tends to kill their red bone marrow cells as well as the cancer cells.
Ineffective erythropoiesis is defined by the expansion of early-stage erythroid precursors driven by erythropoietin, accompanied by the apoptosis of late-stage precursors. . This mechanism is principally responsible for the anemia seen in acquired conditions such as certain subtypes of myelodysplastic syndrome (MDS) and inherited disorders such as β-thalassemia, inherited sideroblastic ...
Continuous erythropoietin receptor activator (CERA) is the generic term for drugs in a new class of third-generation erythropoiesis-stimulating agents (ESAs). In the media, these agents are commonly referred to as 'EPO', short for erythropoietin .

Epoetin beta , sold under the brand name Neorecormon among others, is a synthetic, recombinant [4] form of erythropoietin, a protein that promotes the production of red blood cells. It is an erythropoiesis-stimulating agent (ESA) that is used to treat anemia , commonly associated with chronic kidney failure and cancer chemotherapy .
