Oogonia (OvC)


Ovr.OvC.Ogn
Oogonia are mitotically dividing cells, which enter prophase of the first meiotic division at E13.5, and then arrest at the dictyate stage of the first meiotic prophase to form oocytes in the fully differentiated ovary.

After differentiation of Primordial germ cells, oogonia undergo mitotic proliferation with incomplete cytokinesis, leaving daughter cells connected by intercellular bridges.  The oogonia multiply mitotically, but when meiosis is initiated, terminating mitotic proliferation, they are termed oocytes. In the human fetus: between 8 and 13 weeks
