Gourt Home::Gourt :: Normoblast
A normoblast (or erythroblast) is a type of red blood cell which still retains a cell nucleus. It is the immediate precursor of a normal erythrocyte.
An unusually large erythroblast is called a "megaloblast", and can be associated with pernicious anemia and folic acid deficiency
Development
There are four stages in the development of a normoblast.
- Pronormoblast
- Basophilic normoblas
- Polychromatic normoblast (also polychromatophilic)
- Orthochromatic normoblast (also orthochromatophilic)
