Fig. 6. APC proteins are not essential for embryonic cell adhesion. (A-F) Stage-matched stage 9-10 wild-type and mutant embryos labeled for Arm, DE-cadherin, -catenin and Dlg (a basolateral marker), as indicated. To select M/Z APC2^g10 APC1^Q8 embryos, females carrying germline clones were crossed to moeGFP APC2^g10 APC1^Q8/+ males. Wild-type, his-GFP-marked embryos stained in the same tubes. (E'',F'') z-axis cross-sections of E,F. Arrows indicate adherens junctions. Scale bar: 10 µm for A-F'; 2.5 µm for E'',F''.
