Fig. 7. GFP-Ena in filopodia. Movie stills showing embryos expressing GFP-Ena alone (A,B) or with GFP-actin (C) using engrailed-Gal4. Time, minutes:seconds. (A) GFP-Ena at filopodial tip as it extends (arrows). (B) See Movie 1 in the supplementary material. Arrows, GFP-Ena remains at filopodial tip during retraction; arrowheads, GFP-Ena spots move rearward. (C) See Movie 2 in the supplementary material. Arrowheads and arrows, large lamellipodial fan with actin microspikes that fuse at distal tips to form filopodia. Scale bars: 5 µm.
