erythropoeietin


Term:erythropoietin
Literally meaning: protein of  making erythrocytes
Origin: Anc Greek
Origin: Anc Greek
ερυθρός/erythros(=red)
+ποιέω/poieo (=create, make)
Coined/History 
The concept of  a hormone that regulates red blood cell production was proposed in 1906 by Paul Camot and DeFlandres who observed that serum from anemic donor rabbit injected into normal rabbits could lead to erythropoiesis.. The name was introduced by Eva Bonsdorff and Eeva Jalavisto, in 1948, after studying red cell production in animals. Hematologists John Adamson and nephrologist Joseph W Eschbach looked at the role of the natural hormone EPO in the formation of red blood cells and could help to a treatment to anaemia. Finally in 1985 the human erythropoietin gene was cloned by Jacobs et al., and a large scale production began. In 1987 a clinical trial was conducted for a synthetic form of the hormone, Epogen produced by Amgen
