Supplementary Movie 1

H2B-cherry quail embryo filmed from the ventral view with a 10x objective. Note that that tissues seem to elongate toward the posterior pole of the embryo at different velocities, cells in the notochord shown in the red patch move faster than cells in the green patch located in the paraxial mesoderm. Anterior region is on the left.
