Movie 3.

A representative time-lapse recording of an mCherry-labeled st. 4 Japanese quail node orthotopically grafted in a SN-EGFP-labeled embryo from st. 5 to st. 8. This movie shows the development of a st. 4 node into the anterior mesendoderm (AME) and posterior notochord (PNC) and the convergence of the anterior epiblast cells toward the midline. The frames were at 10 min intervals and shown at 6 fps. The original data for Figure 1(B)(a).
