Width of cluster over time. Left: Cluster size, both in width and in number of bound integrins, over time for a collagen fiber radius of 500 nm. Right: Cluster width in time for three different diameters of fiber. It is clear that width and number of integrins do not share a direct correlation, as there is an issue of density. However, overall trends are the same, and while width is easier to compare to experiment, number of bound integrins is an extremely important quantity.
