Reticulocyte

contain some cell organelles and are the initial form of erythrocytes (red blood cells, RBCs) that enter the blood (circulation).
remain for a few days in either bone marrow or spleen to mature to erythrocytes.
may be visible in blood smears by a very slight basophilic staining (homogeneous or stippling).

Erythropoiesis

proerythroblast - large, slightly basophilic cell, which contains a large, lightly stained nulceus.
basophilic erythroblast
polychromatophilic normoblast
orthochromic normoblast
reticulocyte
erythrocyte

Proerythroblasts

proliferate to generate a sequence of cells
each show a gradual decrease in size and condensation of their chromatin.
each named after changes in the staining (basophilic, polychromatophilic and orthochromic) of their cytoplasm.
nucleus is finally extruded from the normoblast. The cell enters circulation as a reticulocyte, which still contains some organelles.
