erythropoietin
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.
