Schematic diagram of signaling crosstalk that regulates the formation of ovarian niche cells and germ cells. The Hippo, Insulin and Tor signaling pathways function in the soma to regulate proliferation both autonomously in TFCs and ICs and non-autonomously in GCs. The Notch signaling is required for TFC and CC formation. The EGFR pathway regulates homeostatic growth of both IC and GC numbers
