Enhanced α-tubulin expression on convex geometric structure. (A) Representative fluorescence images of α-tubulin (red) in MDCK cells on the flat, triangle, square, and circle structure. (B) The box plots indicate the total intensity of α-tubulin per individual cells on corner of triangle (navy), square (orange), and circle (red) structure. The result from flat surface is plotted in gray color as a control (N = 6). (C) Mean relative α-tubulin intensity of the cells on the geometric structure compared to that on the flat surface. for flat surface and triangle, square, circle structure was 4893 and 603, 704, 1487, respectively (N = 6). Error bars in graph indicate S.E.M. One-way ANOVA with post-hoc Fisher’s LSD was used. **** p < 0.0001; NS, non-significant.
