Supplementary Movie 4

(related to figures 5&6):
Robustness of vector field and deformation patterns through time. This movie is a series of 3 short movies illustrating the fact that vector field and tissue deformation patterns described in figure 5 and 6 can been seen through different time-points during time-lapse analysis. The time is labeled in white on the bottom right of the movies. Anterior is on the left. H2B-cherry quail embryo filmed from the ventral view with a 20x objective. Z layer selected correspond to the middle of the embryo. Movies of vector field, tissue rotation and expansion are shown as labelled.
