Figure 1

Velocity field maps of zebrafish from mid-gastrula to early segmentation stages. (A) Dorsal views of GFP-histone H2B-tagged embryos at 8 hpf (80% epiboly), 9 hpf (90% epiboly), 10 hpf (100% epiboly), 10.5 hpf (1 somite), 11 hpf (1–3 somite stages) respectively. Velocity field maps of the dorsal (B) and ventral (C) views of the velocity field maps. The length of the velocity vector represents the magnitude of the domain velocity over a 2-min interval. The color of the vectors represents the directions: Green towards animal pole, Red towards Vegetal pole, and Blue color represents the medio-lateral convergence or divergence. For all views, the embryo is oriented with anterior (A) and posterior (P) to the top and bottom respectively. Scale bar—10 µm.
