Bone Marrow Histology
Megakaryoblast
- precursor of megakaryocyte.
- earliest identifiable precursor in the thrombocytic series.
- matures to form the promegakaryocyte.
Megakaryocyte
- largest cells observed in the bone marrow.
- responsible for platelet production.
- develop through a process called endoreduplication, which forms cells with 16N and 32N chromosomal content.
- large amount of DNA increases protein production and cytoplasm volume.
- platelets form by pinching off from the cell surface.
Thrombocyte
- platelets form by pinching off from the cell surface of a megakaryocyte.
