primitive red blood cell
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. [ http://dx.doi.org/10.1097/MOH.0b013e3282f97ae1 http://www.ncbi.nlm.nih.gov/pubmed/11495698 ]
