Intact apical brush border and tight junctions in lkb1-mutant intestines. Transmission electron microscope micrographs of WT and lkb1-mutant intestinal cells at 7 dpf. (A) The microvilli constituting the apical brush border are depicted in the intestinal cells. (B) Lkb1-mutant intestinal cells also have microvilli and an apical brush border in their apical surface. Magnifications show hemidesmosomes (black arrows) and tight junctions (red arrows) in WT and lkb1-mutant intestinal cells.
