a-c, Average spatiotemporal distributions of a, aPARs
(PAR-6::mCherry) and pPARs (PAR-2::GFP) (both N = 9 embryos), b,
myosin (NMY-2::mKate2; N = 6 embryos) together with c, the myosin
flow field (N = 9 embryos) during polarity establishment for the PAR-2
MT-mutant. d-f, Comparison of MACE data for the PAR-2 MT-mutant
(dots, shaded regions represent standard error of the mean) to theory
predictions (displayed at t = 50 s, 200 s and 450 s; see Supplementary Video 3).
h-j, Average spatiotemporal distributions of h,
aPARs (PAR-6::mCherry) and pPARs (PAR-2::GFP) (both N = 6 embryos),
i, myosin (NMY-2::GFP; N = 8 embryos) together with
j, the myosin flow field (N = 12 embryos) during polarity
establishment of the unperturbed condition. k-m, Comparison of MACE
data for the unperturbed condition (dots, shaded regions represent standard
error of the mean) to theory predictions (displayed at t = 50 s, 200 s and 450
s; solid lines); see Supplementary Video 4. g,n, Comparison of the measured
and predicted PAR-2 domain width for the unperturbed condition (n)
and the PAR-2 MT-mutant (g). Error bars are standard error of the
mean.
