Lesson plan
Pole cell
In early Drosophila development, the embryo passes through thirteen nuclear divisions (karyokinesis) without cytokinesis, resulting in a multinucleate cell (generally referred to as a syncytium, but strictly a coenocyte ). Pole cells are the cells that form at the polar ends of the Drosophila egg, which begin the adult germ cells. Pole plasm functions to bud the pole cells, as well as restore fertilization, even when the cell was previously sterile.
