(A) Schematic of a Drosophila egg chamber. Exchange of molecules occurs via physical connections through RCs.

(B) Schematic of a secondary mammalian follicle. Exchange of molecules is thought to occur via physical connections, including transzonal projections and connections in the cumulus-oocyte complex.
