Erythropoiesis (from Greek 'erythro' meaning red and 'poiesis' meaning to make) is the process which produces red blood cells (erythrocytes). It is stimulated by decreased O 2 in circulation, which is detected by the kidneys, which then secrete the hormone erythropoietin.
What is erythropoietin (EPO)? Erythropoietin is an important hormone produced by the kidney that is critical in the formation of red blood cells by the bone marrow. Diseases that may result from lack of EPO include anemia, kidney disease, kidney tumor, or polycythemia.
