Polychromatophilic erythroblast

In the basophilic erythroblast stage, the cell began to synthesize hemoglobin. Its accumulation changes the tinct properties so that the polychromatophilic erythroblast is both eosinophilic (acidophilic) due to hemoglobin and basophilic due to ribosomes in the cytoplasm. The resulting color of the cytoplasm is thus a combination of both colors or eosinophilic and basophilic regions are visible in them. The nucleus is again smaller and more condensed compared to the previous stage.
