Figure 2.

Relative cell density increase δn/n = (n₀ − n(5 min))/n₀ of HT29 cells 5 min after an external pressure jump as a function of radial distance r normalized by spheroid radius R (circles). Here n₀(r) denotes the cell density at radius r before the pressure jump. Data as shown in figure 1a. Fit of to the experimental data, corresponding to the theory given by equation (4.13) (solid line). Fit parameters and fit quality χ² = 0.73. (Online version in colour.)
