Fig. 4. (A–C) micrographs of samples with increasing cell density (A: 32 cells per mm2, B: 320 cells per mm2 and C: 1600 cells per mm2). (D–F) Cell covered area A(t) for the four shear velocity zones for measurements as shown in (A–C). The data points represent normalized mean values and standard deviations of five independent preparations and detachment experiments.
