## Figure 3.
Effect of Fg concentration on integrin cluster distance from cell edge. Integrin cluster location is measured as the distance of each cluster from the cell
edge, normalized by the distance from the cell center to the cell edge. Two example
frequency distributions and estimated gamma probability distribution functions for
integrin clusters > 0.5 μm^{2 }are shown for cells adhering to: (a) 2 μg/mL Fg, and (b) 200 μg/mL Fg. The gamma distribution
parameters α and β which were determined by least squares fitting of the gamma distributions
to the frequency distributions of locations of integrin clusters in cells adhering
to 2-200 μg/mL Fg, are shown in (c) and (d) along with 95% confidence intervals on
the parameter estimates. (e) shows the calculated expected (mean) value for the distribution
of integrin cluster location in cells adhering to each Fg concentration.
