Note: Based on the mean alignment direction of six samples from each time point (data are representative of n = 4, 2–3 images per gel.), statistical correlations coefficients were calculated of cellular alignment with circumferential (gel perimeter) direction along gel edge. A value of 1 is perfect positive correlation, 0 indicates uncorrelated
