Fig. 6. Apical markers are correctly localized in the lulu neural
plate. (A-H) Immunofluorescence on transverse sections of E8.5
wild-type (WT; A,C,E,G) and lulu mutant (B,D,F,H) neural plates.
(A,B) ZO-2 marks the tight junctions at the apical-basal border of the
neuroepithelium. (C,D) N-cadherin marks adherens junctions. (E,F) Crumbs is
restricted to the apical surface. (G,H) Pals1 is localized to the apical and
apico-lateral domain. Dorsal is up in all panels. Scale bar: 10 µm in A,B;
5 µm in C-H.
