DB elongation in Sqh-GFP knock-down embryos
Time lapse imaging of Tr3 DB elongation in sqhAx3/Y; sqh-Sqh-GFP, btl-Gal4, UAS-mCherryNLS/+ control (left) and sqhAx3/Y; sqh-Sqh-GFP, btl-Gal4, UAS-mCherryNLS/UAS-deGradFP Sqh-GFP knock-down (right) embryos (5min intervals, 63x objective). Tip cell migration and subsequent DB elongation is indistinguishable between Sqh-GFP knock down and control embryos.
