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.
Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. [1] It is stimulated by decreased O 2 in circulation, which is detected by the kidneys, which then secrete the hormone ...
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.
One small 2016 study found that men with low T between the ages of ... "Testosterone stimulates the production of a hormone called erythropoietin (EPO) and decreases the production of a hormone ...
Erythropoietin (EPO) Extraglomerular mesangial cells: Stimulate erythrocyte production Calcitriol (1,25-dihydroxyvitamin D 3) Proximal tubule cells Active form of vitamin D 3. Increase absorption of calcium and phosphate from gastrointestinal tract and kidneys inhibit release of PTH. Thrombopoietin: stimulates megakaryocytes to produce ...
Epoetin alfa, sold under the brand name Epogen among others, is a human erythropoietin produced in cell culture using recombinant DNA technology. [8] [9] Epoetin alfa is an erythropoiesis-stimulating agent. [8]
In addition to the specialized endocrine organs mentioned above, many other organs that are part of other body systems have secondary endocrine functions, including bone, kidneys, liver, heart and gonads. For example, the kidney secretes the endocrine hormone 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 .
