Erythrocyte
-
Toggle ItemRBC 20XA: Red blood cells usually stain red and are biconcave so the center often stains slightly lighter. Histologically they are named erythrocytes.
B: Platelet -
Toggle ItemRBC 40XA: Erythrocytes
B: Patelets
Lymphocyte
-
Toggle ItemLymphocyte 40XA: Lymphocyte
B: Erythrocyte
C: Neutrophil -
Toggle ItemLymphocyte 100XA: Lymphocyte has a very dark densely stained nucleus and a visible cytoplasm.
-
Toggle ItemLymphocyte 100X-2- 20-50% of WBCs
- Life span is months to years
- General immunity
Monocyte
-
Toggle ItemMonocyteA: Monocytes are usually shaped like a kidney bean due to their large bi-lobular nucleus. The nucleus also stains much less dense than a lymphocyte
- 2-10% of WBCs
- 2-5 day lifespan in circulation and 1-3 months in tissue
- Function as phagocytes
B: Lymphocyte with a markedly more dense staining nucleus
C: Basophil with obvious large purple granules obscuring the cytoplasm
Megakaryocyte
-
Toggle ItemMegakaryocyte 20XA: Megakaryocytes are large cells that give rise to platelets or thrombocytes through a process called thromobopoiesis. The cytoplasm of this large megakaryocyte pinches off small portions of its cytoplasm to form the platelets.
-
Toggle ItemMegakaryocyte 40XA: Megakaryocyte is much larger than any of the other WBCs located in this bone marrow sample
B: Immature agranulocyte
C: Immature granulocyte -
Toggle ItemMegakaryocyte 100XA: Platelets or histologically named thrombocytes are anucleate pieces of megakaryocyte cytoplasm. They form plugs, promote clot formation, and secrete factors that modulate coagulation
