Overview

An erythroblast is a type of red blood cell which still retains a cell nucleus. It is the immediate precursor of a normal erythrocyte.

Nomenclature

The term normoblast is sometimes used as a synonym for erythroblast, but at other times it is considered a subcategory. In the latter context, there are two types of erythroblasts:

• "normoblasts" - develop as expected
• "megaloblasts" - an unusually large erythroblast that can be associated with pernicious anemia and folic acid deficiency (collectively called megaloblastic anemia)

Development

There are four stages in the development of a normoblast.

	Pronormoblast
	Basophilic normoblast
	Polychromatic normoblast (also polychromatophilic)
	Orthochromatic normoblast (also orthochromatophilic)
