Erythropoietin (EPO) is a hormone produced by the kidney that promotes the formation of red blood cells by the bone marrow.
Erythropoietin is categorized under glycoproteins, which are substances that act as stimulants for the development of certain types of blood cells. When the erythropoietin promotes the production of more red blood cells in the bone marrow, it will result in an increase in the capacity of the blood to carry oxygen.
