Movie S1 from Effects of dynamic matrix remodelling on <i>en masse</i> migration of fibroblast on collagen matrices

Trajectories of cells migrating on low density (1.5 mg/mL) and high density (6.0 mg/mL) collagen matrices determined by time-lapse imaging followed by single particle tracking. Trajectories are superimposed on bright field (left) and quantum dot intensity (right) micrographs.
