The correct answer is b. It stimulates red blood cell production by affecting progenitor cells.
Erythropoietin is a hormone, produced mainly in the kidneys, which stimulates the production and maintenance of red blood cells.
Erythropoietin acts by binding to its cell surface receptor which is expressed at the highest level on erythroid progenitor cells to promote cell survival, proliferation, and differentiation in production of mature red blood cells.Jan 17, 2020
- The hormone that regulates red blood cell production (erythropoietin, EPO) is produced by the kidney. When the kidney detects low blood oxygen, it releases EPO stimulating red blood cell formation (erythropoiesis).
