Fig. 6. DE-cad accumulation is modulated upon Egfr activity. (A-G)
Projections of confocal sections showing small groups of tracheal cells
expressing actinGFP and EgfrDN (A-D) or
top (E-G) under the control of btlGal4. The embryos
are labelled with DCAD2 (red) and anti-GFP (green). Greyscale images of DCAD2
are shown separately in panels A'-G'. Note a decrease in DE-cad in cells
marked with actinGFP compared with the surrounding cells in A-D, and
an increase in E-G (arrows).
