Figure Caption

Fig. 3 Reduced expression of bbs8 and vangl2/tri results in laterality defects. Cardiac looping and the laterality marker expression. A-D) Cardiac looping at 30 hfp. A) Normal looping (D-loop). B) Reversed looping (L-loop). C) Absent looping. The heart tube is highlighted by a red dotted line (A-C). D) At 30 hpf, injected tri^-/- embryos exhibited increased percentages of abnormal cardiac looping. The fractions of embryos of each category are noted in percent along the X-axis. E-G) spaw expression (arrowheads) in 15-16-somite embryos. E) Normal spaw expression on the left lateral mesoderm. F) Bilateral and G) inverted spaw expressions. H) Quantitative representation of spaw expression. In tri embryos injected with bbs8-MO, the expression is randomised. Views: ventral (A-C), dorsal (E-G).
