Supplementary Figure 2: Celsr1 polarity in early and polarizing placodes.

Additional examples of Celsr1 asymmetry in early (left) and polarizing placodes (right) representative of 15 measured images from four embryos shown in Figure 2C. The orientation of the line shows the direction of Celsr polarity relative to the AP axis (0 degrees). 0–44 degrees is shown in cyan and 45–90 degrees is shown in yellow. Scale bar, 10μm. Anterior is to the left.
