Movie 10.

Mesendodermal clone dispersal in caAlk8 overexpressing explants. Maximum intensity projection of fluorescence/brightfield high-resolution time-lapse imaging of blastoderm explants showing tracked clonally labeled cell nuclei in the mesendoderm (red) of explants prepared from embryos overexpressing 30pg caAlk8 from 24 minutes before the onset of extension (mbe). Time is shown in minutes. Scale bar: 100 μm.
