Movie 7.

Ectodermal clone dispersal in wildtype explants. Maximum intensity projection of fluorescence/brightfield high-resolution time-lapse imaging of blastoderm explants showing tracked clonally labeled cell nuclei in the ectoderm (blue) from 24 minutes before the onset of extension (mbe). Spots corresponding to individual tracked ectodermal progenitors color-coded based on the individual track ID and corresponding cell trajectories generated in Imaris from 24 minutes before the onset of extension (mbe). Time is shown in minutes. Scale bar: 100 μm.
