Movie 2.

Motile cilia in the posterior neural tube of a 2 dpf cc2d2a -/- embryo with a curled down tail. Arrowheads point to the neural tube. Differential interference contrast images were captured at 60 frames per second and playback speed is real time. Timestamp=seconds. n=7/7 (number of mks6 mutant embryos with motile neural tube cilia/number of embryos analyzed).
