Oogenesis

Oogenesis is development of female gametes; the unequal divisions of human meiosis produce polar bodies alongside the developing ovum.

A germline-associated cell supplying macromolecules to an oocyte in systems such as Drosophila. Maternal RNA synthesis and its eventual localization are distinct processes.

A somatic cell surrounding an oocyte. In Drosophila melanogaster, ovarian follicle cells interpret oocyte signals and contribute to eggshell pattern and later embryonic positional information.

A polar body is a small product of an unequal division during oogenesis.
