WebErythropoietin is a type of protein called a growth factor. It stimulates the bone marrow to make red blood cells. Red blood cells contain a protein called haemoglobin (Hb). It carries oxygen around the body. The body makes erythropoietin naturally. But it is also made as a drug to treat a low number of red blood cells (anaemia). Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. It is stimulated by decreased O2 in circulation, which is detected by the kidneys, … See more In the process of red blood corpuscle maturation, a cell undergoes a series of differentiations.
