MICROANATOMY

Detailed explanation-1: -Erythropoietin (EPO) is a glycoprotein hormone, naturally produced by the peritubular cells of the kidney, that stimulates red blood cell production. Renal cortex peritubular cells produce most EPO in the human body. PO2 directly regulates EPO production.

Detailed explanation-2: -Erythropoietin (Epo) is a glycoprotein that promotes the proliferation and differentiation of erythrocyte precursors. The major site of Epo production is the kidney, while the liver is the main extrarenal site of Epo production.

Detailed explanation-3: -Although the liver is the major site of erythropoietin (Ep) production in the fetus, this function is assumed by kidneys in the adult.

Detailed explanation-4: -Abstract. Erythropoietin, a glycoprotein hormone, is synthesized predominantly in the kidney and secreted by renal cortical interstitial cells in response to tissue hypoxia. Erythropoietin is the main regulator of the production of red blood cells.

Detailed explanation-5: -The kidneys and liver produce erythropoietin when oxygen levels in the cells are low. The hormone then stimulates the bone marrow, which, in turn, makes more red blood cells. It is normal for a small amount of erythropoietin to circulate in the blood, as this helps replenish the body’s natural blood stores.
