Crawling velocity of a cell crossing a boundary between substrates of different stiffnesses. Cells crawl faster when they move from a soft to stiff substrate and slow down when moving from a stiff to soft substrate. (Black contour line) Point where the crawling velocity is zero, which gives the furthest distance a cell can invade into a soft substrate. (Colorbar) Arbitrary units are used.
