Figure 3—figure supplement 4.

(A) Shapes of the speed of intrinsic mobility gradient v₀(x) in Equation (3) in the Materials and methods for different values of the maximum speed at the tailbud v_s. The origin of the horizontal axis is the anterior end of the PSM xa, x-=x-xa. (B) Time evolution of the mean squared difference of displacement vector (MSDD) for different values of v_s. The grey circles and squares indicate the MSDDs of two 17 somite-stage embryos quantified previously (Uriu et al., 2017, in the main text) as references. (C) Dependence of FRS (blue) and PLD (green) on v_s. The box-whisker plot indicates (0.05, 0.25, 0.75, 0.95) quantiles of FRS and PLD for 100 realizations of simulations. The white bars indicate median. The shaded interval of v_s is the range within which simulated MSDD is close to those from embryonic tissues shown in (B).
