Description: A large nucleated basophilic erythrocyte found in mammalian embryos. This cell type arises from the blood islands of yolk sacs and expresses different types of hemoglobins (beta-H1, gamma-1 and zeta) than adult erythrocytes. Considered a type of erythroblast as this cell type can enucleate in circulation.

Synonyms: primitive erythroblast, primitive erythrocyte, primitive erythroid cell
