GENERAL HISTOLOGY

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.

Detailed explanation-2: -The renal glycoprotein hormone erythropoietin (Epo) is the key element in the feedback control of the production of red blood cells (RBC) in bone marrow. Excess of antidiuretic hormone (ADH) increases the RBC mass by increasing the synthesis of Epo.

Detailed explanation-3: -Lack of O2 (hypoxia) is a stimulus for the synthesis of erythropoietin (Epo), primarily in the kidneys.

Detailed explanation-4: -A key player in red blood cell production is erythropoietin. It is a glycoprotein hormone, mainly produced by the kidneys, that promotes erythroid progenitor cell survival and differentiation in the bone marrow and regulates iron metabolism.
