Elastic behavior quantification. (A) Snapshots of one tissue sphere aspirated in a hole at increasing pressure steps (top to bottom). The dashed red line shows the position of the aspirated tongue at each step, and L is the aspirated length. (B) Linear relationship between the applied pressure and $\delta z$ for a single tissue sphere and 10 different pressure steps showing both the linear behavior (fitted as a blue line) and negative intercept. (C) Same measurement as in (B), repeated on n = 36 tissue spheres, each represented by a differently colored line. (D) distribution of Young’s moduli obtained by this method. Black dots are individual measurements; the box plot shows the median and quartiles of the distribution. We found E = (4.4 ± 3.3) × 10² Pa (mean ± standard deviation, n = 36).
