The distribution of cellular elasticities estimated from applying the Hertz model (Eq. (2)) to the force-indentation data. Solid lines show the dynamic peak function model fits the data presented in the histograms (Origin v9.4, OriginLab Corp., Northampton, MA). The lognormal dynamic peak function model was used to fit unimodal distributions while the Gaussian dynamic peak function model was used to fit multimodal distributions. Peaks are reported in MPa. When more than one peak is present in the histogram, the reported r² value represents the average for all fits.
