Supplementary Figure 7: Examples of PIV and Fourier analysis of periodic contractions in different conditions.
From: Pulsatile cell-autonomous contractility drives compaction in the mouse embryo
a–f, Four examples of PIV and Fourier analysis are shown for 8-cell stage embryos (a, black), 4-cell stage embryos (b, blue), 8-cell stage embryos without zona pellucida (c, no ZP, purple), 8-cell stage embryos treated with 25 μM Bb (−) (d, orange) or 1 μM CCD (e, yellow), and mzCdh1−/− 8-cell stage embryos (f, green) are shown. The left column shows the velocity of one vector in one direction over time. The middle column shows the corresponding power spectrum. The right column shows the amplitude as a function of the period.
