Erypoethin
WebJul 18, 2024 · erythropoietin: [noun] a glycoprotein hormone formed especially in the kidney and stimulating red blood cell formation. Erythropoietin levels in blood are quite low in the absence of anemia, at around 10 mU/mL. However, in hypoxic stress, EPO production may increase up to 1000-fold, reaching 10 000 mU/mL of blood. In adults, EPO is synthesized mainly by interstitial cells in the peritubular capillary bed of the renal cortex, with additional amounts being produced in the liver, and the pericytes in the brain. Regulation is believed to rely on a feedback mechanism measuring blood …
