Figure 2. Anatomy of an ovarian follicle.

Figure 2

This cartoon depicts the various cell types of an antral follicle and some of the factors secreted by each cell type. The oocyte is surrounded by cumulus granulosa cells, while the mural granulosa cells surround the antrum. The theca cells surround the entire follicle. Crosstalk between these cell types by the factors listed and others are important for ovarian folliculogenesis.
