Movie 1.

Propagation of PCP in the posterior-to-anterior direction in Xenopus neural plate. Time-lapse imaging of polarized GFP-Pk3 aggregate formation during neurulation. Xenopus embryos expressing HA-Vangl2 and GFP-Pk3 RNAs. Dorsal view is shown. Note progressive posterior-to-anterior formation of GFP-Pk3 crescents. The movie is representative of three independent experiments.
