Extended Data Fig. 2: Experimental data of the generation of flow during contractions.

From: Collective intercellular communication through ultra-fast hydrodynamic trigger waves

Extended Data Fig. 2

Data are the same as those presented in Fig. 2c, d, but without the theory data superimposed. The red arrows that denote the long axis of the body are kept for reference. n = 46 experiments. a, PIV measurements of the flow averaged for 40 ms after the onset of contraction. b, Experimental tracer dynamics. White lines are obtained from superposing image frames with FlowTrace software, and the coloured lines are digital PTV particle trajectories obtained with TrackMate software.
