F) Recoil is observed when cuts are made in apical cortex with a 2-photon laser with egg chambers in saggital view. Images show cortex before and after cutting. Scale bars = 10 μm. Yellow arrows indicate edges of ablated region. G) Recoil is higher when cuts are made at the apical cortex at the equator of egg chambers, rather than at the poles. Quantification of experiment shown in (F). Statistical significance tested by Mann-Whitney test. Number of laser cuts: equator n=30, pole n=20. Data information Laser ablation experiments performed on tissue from sqhAX3, sqh::GFP flies.
