- A sialic acid-containing protein that enhances erythropoiesis by stimulating formation of proerythroblasts and release of reticulocytes from bone marrow; it is formed by the kidney and liver, and possibly by other tissues, and can be detected in human plasma and urine. SYN: erythropoietic hormone (2), hematopoietin, hemopoietin.

* * *n.a hormone secreted by certain cells in the kidney in response to a reduction in the amount of oxygen reaching the tissues. Erythropoietin increases the rate of red cell production (erythropoiesis) and is the mechanism by which the rate of erythropoiesis is controlled.
* * *eryth·ro·poi·e·tin (ə-rith″ro-poiґə-tin) a glycoprotein hormone secreted chiefly by the kidney in the adult and by the liver in the fetus, which acts on the bone marrow cells to stimulate erythropoiesis. Called also hematopoietin and hemopoietin.
