Figure S1
Global displacement of mesoderm progenitors.
Movie 1
Elongation motion in Hensen's node region fated to the neurectoderm.
Time-lapse analysis of the GFP population comprising the
posterior neural plate and the node region. Frames are 5 min apart.
Cell behaviours of this movie are summarized in Fig. 3a.
Movie 2
Coherent behaviour of neural progenitors. Two adjacent GFPexpressing
cells retain their relative locations (coherence) during
Hensen's node progression.
Movie 3
Elongation motion in Hensen's node region fated to the mesoderm.
Clusters of axial (mesoderm) progenitors labelled by DiI become
progressively displaced from each other while individual cells
migrate away into the mesoderm.
