DEFINITION:
- polychromatophilic normoblast
-
A nucleated, immature erythrocyte in which the nucleus occupies a relatively smaller part of the cell than in its precursor, the basophilic normoblast. The cytoplasm is beginning to acquire hemoglobin and thus is no longer a purely blue color, but takes on an acidophilic tint, which becomes progressively more marked as the cell matures. The chromatin of the nucleus is arranged in coarse, deeply staining clumps. Called also intermediate normoblast , intermediate or polychromatic erythroblast , and rubricyte .
