noun, plural: megakaryocytes
Megakaryocytes are the mature form of promegakaryocytes that originate from the megakaryoblasts. These cells owe their name from their large cell size that is 10 times larger than a typical erythrocyte. It is large because within the cell the DNA replicates but does not involve cytokinesis. Thus, the cell appears to contain many nuclei but it only has a single nucleus that became large and lobulated.
Word origin: Greek mégas, large + Greek karuo-, nut + -cyte, cell.
