Movie 6.

Representative examples of raw imaging data of the probe tip in embryonic tissues. Probe force constant k = 0.2 N/m, at 10 V, sinewave frequency of 0.5 Hz. Tissue insertion depth is approximately 70 μm. While the motor and probe holder move the same way in each sample, the probe movement amplitudes are distinct. PSM, presomitic mesoderm.
