A proerythroblast (or rubriblast, or pronormoblast) is a precursor cell to the normoblast (nucleated red blood cell), as the earliest of four stages in its development.. In histology, it is very difficult to distinguish it from the other "-blast" cells (lymphoblast, myeloblast, monoblast, and megakaryoblast).
