Pole cell

Pole cell

In early Drosophila development, the 13 first mitosis are nuclear divisions without cell division, resulting in a multinucleate cell (a syncitium). The first mononucleate cells are created at the posterior pole, were the polar granules are tethered. These cells are called pole cells, and they will form the fly's germ line.
