Erythropoiesis Quiz

Study Notes

Stages of Erythropoiesis and Characteristics of Each Stage

Rubriblast is the largest and first identifiable cell of erythropoiesis, with a round to oval nucleus and dark blue cytoplasm.
Prorubricyte has a chromatin-condensed nucleus with a richer blue cytoplasm and detectable hemoglobin synthesis.
Rubricyte has a reduced nucleus with pink-stained cytoplasm, reflecting hemoglobin accumulation and decreasing RNA.
Metarubricyte has a tightly condensed nucleus that is extruded from the cell, with acidophilic cytoplasm indicating large quantities of hemoglobin.
Reticulocyte is a polychromatic erythrocyte with no nucleus, remaining in the bone marrow for two days and one day in the peripheral blood.
Stress or shift reticulocytes appear during acute bleeding, demonstrating immature RBCs in the peripheral blood.
Mature erythrocyte appears as a salmon pink-staining cell with central pallor and an average diameter of 6 to 8 um.
The nucleus takes up much of the cell in the rubriblast stage, with a N:C ratio of 8:1.
The prorubricyte stage has a N:C ratio of about 6:1 and contains many cytoplasmic organelles that mask the minute amount of hemoglobin pigmentation.
Rubricyte stage is the last stage capable of undergoing mitosis and has a length of 30 hours.
Metarubricyte stage has a length of 48 hours and is characterized by a pyknotic nucleus and extrusion of the nucleus from the cell.
Radioactive chromium (51Cr) can be used to determine the survivability of erythrocytes.
