proerythroblast

 [pro″ĕ-rith´ro-blast]
the earliest erythrocyte precursor in the erythrocytic series, preceding the basophilic erythroblast and having a large nucleus containing several nucleoli, surrounded by a small amount of cytoplasm. The term may encompass both normal and abnormal red cell precursors, in which case the two types may be called pronormoblast and promegaloblast, or it may be used to mean a normal precursor only, as synonymous with pronormblast. Called also rubriblast.
