Bone marrow: Megakaryocytes
This image shows megakaryocytes at high magnification. Megakaryocytes are extremely large cells that possess a single, highly lobulated, polyploid nucleus. Megakaryocytes produce platelets which form by fragmenting from the cell. During development, megakaryocytes undergo atypical nuclear divisions resulting in polyploidy nuclei that contain three or more multiples of the diploid number of chromosomes. 600x, 1000x
