Extended Data Fig. 4: Comparison of experimental and theoretical flows induced by a cell contracting in a liquid film.
From: Collective intercellular communication through ultra-fast hydrodynamic trigger waves
Flow velocities are shown, as a function of distance from the organism. Results were obtained experimentally (PIV) and theoretically (LNS model; Supplementary equation 27), and both are averaged for the 40 ms after the onset of contraction. These are the same data as are shown in Fig. 2c, shown differently to aid quantitative comparison. Blue and red colours indicate flows in the longitudinal and transverse directions, respectively, of the elongated cell, which is shown in green for reference. Points indicate experimental data and lines indicate the model. n = 46 experiments.
