Figure 3.

Average relative counts of projected cell areas of adhering A. castellanii on PDMS substrates and on the control substrates. The histograms show that the distribution is slightly asymmetric and can therefore not be fitted with a Gaussian. Average relative counts were calculated by determining the relative counts per sample and generating the average for each bin from all experiments, in order to equally rate all experiments. The value above the interception of the x-axis shows the relative counts of cell adhesion areas larger than 1750 µm². Differences in cell area distribution become particularly visible when comparing the pie charts (white: cell adhesion area < 600 µm²; black: 600 µm² ≤ cell adhesion area ≤ 1200 µm²; striped: cell adhesion area > 1200 µm²).
