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.
The 2020 Cochrane Anaesthesia Review Group review of erythropoietin (EPO) plus iron versus control treatment including placebo or iron for preoperative anaemic adults undergoing non‐cardiac surgery [11] demonstrated that patients were much less likely to require red cell transfusion and in those transfused, the volumes were unchanged (mean ...
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 in neuroprotection is the use of the glycoprotein erythropoietin (Epo) for neuroprotection. Epo controls erythropoiesis , or red blood cell production. Erythropoietin and its receptor were thought to be present in the central nervous system according to experiments with antibodies that were subsequently shown to be nonspecific.
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.
The systems activated by hypoxia usually help cells to survive and overcome the hypoxic conditions. Erythropoietin, which is produced in larger quantities by the kidneys under hypoxic conditions, is an essential hormone that stimulates production of red blood cells, which are the primary transporter of blood oxygen, and glycolytic enzymes are ...
The lack of oxygen (hypoxia) causes cell death in a localized area which is perfused by blood vessels failing to deliver primarily oxygen, but also other important nutrients. While ischemia in most tissues of the body will cause coagulative necrosis, in the central nervous system ischemia causes liquefactive necrosis , as there is very little ...
In adults, the majority of hematopoiesis occurs in the bone marrow. Significant production in any other organ is usually the result of a pathological process. When red blood cell (RBC) numbers are low, the body induces a homeostatic mechanism aimed to increase the synthesis of RBCs, typically via the production of erythropoietin. If the loss of ...
