The cells indicated by arrows are E6 cells. The nuclei are shrunken and extremely pyknotic. The nucleus with a small amount of cytoplasm will soon be extruded (E7 cell) and immediately phagocytized by a histiocyte. The cytoplasm, after the loss of the nucleus, still contains a small amount of RNA and is called a reticulocyte. After three days, the reticulocyte loses its polychromasia due to RNA and becomes a mature erythrocyte for 120 days.
