FIG. 2.

Toroid width is independent of trough width. Monodispersed cells (20 [closed symbols] or 40 [open symbols] cells/μm of circumference) were seeded onto micromolds containing toroid-shaped recesses whose peg had the same diameter (600 μm) but whose circular tracks had varying widths of 400 (•, ○), 600 (▾, ▿), or 800 (▪, □) μm. Width of the toroids as a function of time is plotted for each design. n = 39 (400 μm, 20 cells/μm, •,), 47 (400 μm, 40 cells/μm, ○), 45 (600 μm, 20 cells/μm, ▾), 30 (600 μm, 40 cells/μm, ▿), 26 (800 μm, 20 cells/μm, ▪), and 11 (800 μm, 40 cells/μm, □). Error bars represent standard deviation.
