Table 1. Parameter values obtained by fitting the tangential cell elongation profile shown in Figure 6C to the self-organized model.

Values in the last two rows are boundary conditions that are required to calculate the tangential cell elongation profile. The reported parameter uncertainty intervals were obtained by fitting 101 uniformly sampled tangential cell elongation profiles from the range defined by the standard deviation in the experimental tangential cell elongation profile (error bars in Figure 6C). The interval limits are the 10^th and 90^th percentiles of the obtained values.

Fit parameter	Parameter value	Uncertainty interval
$q_0^2$	${\displaystyle 0.01}$	${\displaystyle [-0.06,0.11]}$
$\lambda \tau$	${\displaystyle 1.0}$	${\displaystyle [0.2,1.3]}$
$\frac{D}{\alpha }$	${\displaystyle 0.5\mu m^2}$	$\left[0.2,\mathrm{}27\right]{\mu m}^2$
$\frac{1}{D}\left(\frac{1}{\tau \lambda }+2K\mu \tau \right)R_{rr}$	${\displaystyle 9\cdot {10}^{-4}\mu m^{-2}}$	${\displaystyle \left[0.0,3.2\right]\cdot {10}^{-3}\mu m^{-2}}$
$q_{rr}\left(r_{in}\right)$	${\displaystyle 0.024}$	${\displaystyle [0.014,0.105]}$
${\partial }_r{q}_{rr}\left(r_{in}\right)$	${\displaystyle -1.2\cdot {10}^{-3}\mu m^{-1}}$	${\displaystyle \left[-9.3,0.0\right]\cdot {10}^{-3}\mu m^{-1}}$
