Fluorescence images of the actin cytoskeleton of the cells on (a) G1, (b), G2 substrates and (c) control sample after 5 days of culture (Scale bar 50 Ī¼(S. The white arrow shows the longitudinal direction of the patterns. (d-f) Distribution of cells nuclei alignment angles on the patterned and control samples, (g) Percentage of cells that have orientation angles within 0-10 degree angle, (h) Cellular elongation function of cell orientation angle within the patterned substrates (i) Proliferation of the cells on the patterned and control substrates.
