PATHOLOGY

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: -Artificially increasing your erythropoietin levels produces more haemoglobin and red blood cells and therefore improves the amount of oxygen that can be delivered to tissues, particularly muscles.

Detailed explanation-3: -Erythropoietin is a hormone that your kidneys naturally make to stimulate the production of red blood cells. High or low levels of erythropoietin can cause health problems. A healthcare provider can measure your erythropoietin levels with a blood test.

Detailed explanation-4: -Erythropoietin is produced by interstitial fibroblasts in the kidney in close association with the peritubular capillary and proximal convoluted tubule. It is also produced in perisinusoidal cells in the liver. Liver production predominates in the fetal and perinatal period; renal production predominates in adulthood.
