Figure Caption
Fig. 4 Myotendinous junctions are altered in popdc2 morphants. Confocal imaging of the trunk musculature of 24 hpf embryos in a lateral view, anterior to the left. (A,B) FAK and (C,D) vinculin expression in (A,C) MO-control and (B,D) MO1-popdc2 injected embryos. In the popdc2 morphants the shape of the myotomal boundaries is disturbed and the expression domains of FAK and vinculin are discontinuous (arrow heads). (A′–D′) Beta-catenin staining. (A′′–D′′) Merge of panel (A–D) and (A′–D′). Scale bar = 50 μm.
