Explanation:
Detailed explanation-1: -Erythropoietin is distinct among the hematopoietic growth factors because it is produced primarily in the kidneys rather than the bone marrow.
Detailed explanation-2: -Erythropoietin (EPO) is a hormone that is produced predominantly by specialised cells called interstitial cells in the kidney. Once it is made, it acts on red blood cells to protect them against destruction. At the same time it stimulates stem cells of the bone marrow to increase the production of red blood cells.
