Basophilic erythroblast
From WikiLectures
The basophilic erythroblast is formed by mitotic division of the proerythroblast. The body of the cell is smaller, the nucleus is still round, but its chromatin with every passing mitotic division is more and more condensed, lumpy. The cytoplasm is still strongly basophilic due to the large number of free ribosomes (polysomes), that synthesize hemoglobin and the building proteins necessary for subsequent mitosis. The next cell in the blood line is the polychromatophilic erythroblast.
