Supplementary Figure 1: Streak formation, expansion contraction dynamics and cell behaviour of a different sample embryo.

From: Myosin-II-mediated cell shape changes and cell intercalation contribute to primitive streak formation

Supplementary Figure 1

(a) Images showing the formation of the streak on top images of the embryo as a function of time. (b) Time sequence of the expansion/contraction map. (c) Time sequence of the isotropic and anisotropic strain rates. Symbols and meaning are the same as for the embryo as shown in fig 3a. White scale bar indicates size in panels a, b and c is 200 μm. In panel c the white scale bar also indicates a strain rate of 10−4/sec, as well as a domain displacement speed of 4 μm/min.
