Pole cell In early ''Drosophila'' development, the first 13 passes through mitosis are nuclear divisions (karyokinesis) without cytokinesis, resulting in a multinucleate cell (generally referred to as a syncytium, but strictly a coenocyte〔Willmer, P. G. (1990). Invertebrate Relationships : Patterns in Animal Evolution. Cambridge University Press, Cambridge.〕). The first mononucleate cells are created at the posterior pole, where the polar granules are tethered. These cells are called pole cells, and they will form the fly's germ line. ==References==
