ERYTHROBLAST - 2 reference results
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" - unusually large erythroblasts 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.| Image | Description |
| Pronormoblast | |
| Basophilic normoblast | |
| Polychromatic normoblast (also polychromatophilic) | |
| Orthochromatic normoblast (also orthochromatophilic) |
