Movie 6.

Real-time imaging of SC nuclei in csp^-/- at 48 hpf. A 48 hpf csp^-/- embryo expressing GFP in SC nuclei after h2b-gfp mRNA injection; the embryo was imaged every 4 minutes for several hours by confocal microscopy. Lateral view; anterior to the left and dorsal to the top. This video represents 100 minutes of continuous real-time imaging.
