PDZ-GEF-overexpressing (OE) border cells do not detach from the follicle cell epithelium. Representative example of live stage 9 egg chamber overexpressing PDZ-GEF (slbo-GAL4, UAS-mCD8::GFP/+; +/UAS-PDZ-GEF). PDZ-GEF-overexpressing border cells stay attached to the adjacent anterior follicle cells, which also express slbo-GAL4 UAS-mCD8::GFP, but extend front-directed protrusions (time in h:min). Frames were acquired every 3 min with a 20x objective. Anterior is to the left.
