Definition of erythropoietin in English:



mass nounBiochemistry
  • A hormone secreted by the kidneys that increases the rate of production of red blood cells in response to falling levels of oxygen in the tissues.

    • ‘The mechanism responsible for polycythaemia is the release of the hormone erythropoietin from the kidney as a result of the shortage of oxygen there.’
    • ‘However, if symptoms become severe, a blood transfusion or injections of synthetic erythropoietin, a hormone normally produced by the kidneys, may help stimulate red blood cell production and ease fatigue.’
    • ‘Another important renal response to ischemia is the release of erythropoietin, which stimulates the bone marrow to increase production of red blood cells.’
    • ‘As renal function declines, patients are likely to develop anemia because of decreased renal production of erythropoietin.’
    • ‘The marrow often has to be supported with granulocyte stimulating factor or erythropoietin.’
