Figure 2.

Cell polarization and alignment on ring patterns with different inner radii. (A) Phase-contrast images of cell morphology and alignment in the cell layer on ring patterns with five different inner radii. (B and C) The mean cell aspect ratio (B) and mean cell angle (C) as functions of cell distance from the ring center for rings of different inner radius. (D) The mean cell area shows an independence of distance and inner radius. Scale bars, 200 μm. To see this figure in color, go online.
