Figure EV2. Analysed packed tissues largely hold to several geometrical laws.

Figure EV2

  1. Lewis' law. All samples show a linear relationship between cell area and the number of cell sides (z). Each solid point represents an average of cell areas across all samples. Blue lines show a linear fit to the data.
  2. Aboav–Weaire law. All samples show a linear relationship between the number of cell sides (z) and the product of this quantity with the average number of sides of a cell's neighbour (m). This demonstrates that all samples follow the predicted trend.
  3. To see whether there are any minor deviations from the Aboav–Weaire law, we plotted the inverse of the number of cell sides (1/z) against m. The slight curvature in the profiles demonstrates that there is in fact a minor deviation for most samples, which is consistent with previous studies of random Voronoi tessellations (Hilhorst, 2006).

Data information: In both (A) and (B), solid points represent averaged quantities across all samples, while blue lines show a linear fit to the data.
