Reticulocytes are visually, slightly larger than mature RBCs. Unlike most other cells in the body, mature RBCs have no nucleus, but reticulocytes still have some remnant genetic material (RNA).

Is there nucleus in reticulocyte?

Reticulocytes are young RBCs that lack a nucleus but still contain residual ribonucleic acid (RNA) to complete the production of hemoglobin.

Do Erythroblasts have a nucleus?

Once nuclear condensation is completed, the orthrochromatic erythroblast undergoes enucleation, a process that generates two daughter structures, the reticulocyte, which contains most of the cytoplasm, and the pyrenocyte, which contains the nucleus surrounded by a small cytoplasmic ring.
