Fig 7. Cell contraction associated with migration on thin film and 8μm fiber—(a) Measurement of cell contraction on micron fibers and flat films at day 1 and day 4.
Cell contraction on micron fiber is defined as: (cell length at t0- cell length at t1)/cell length at t1 *: P<0.001. (b) Illustration of cell contraction when migration on flat film. (c) Illustration of cell contraction when migration on 8μm fibers at day 4.
