Fig. 2

The invasion profile of a DIGME device. a The invasion fronts at day 0, 3, 5, and 10 of the same sample described in Fig. 1. b The means and standard deviations of the invasion distance obtained by averaging d _f (θ) over the polar angle θ of a. c-d Scattered plots: the local cell density by counting only the elongated cells (red), or only the rounded cells (green), or all cells (black). Lines: Running average of the scattered data points with a Gaussian kernel. c shows the results at day 3, d shows the results at day 10
