Fig. 3.
Non-cell-autonomous requirement of Mmp activity in dendrite degradation. (A and B) Live confocal images of ppk-Gal4 driving expression of UAS-mCD8::GFP and UAS-Timp in C4da neurons at 20 h APF. C4da neurons are marked as V and V′ in ventral view (A) and as D in dorsal view (B). Arrows point to undegraded larval dendrites. (C-F) Live time-lapse images of WT and Mmp1Q112Mmp2W307 C4da MARCM clones. (C and D) WP stage. (E and F) Twenty hours APF. Arrows point to soma of C4da clones. Anterior is up and dorsal is right in all images. (Scale bars: 100 μm.)
