Monte Carlo simulation of cell proliferation and spheroid formation in the microwells.

<p>Cross sections of a microwell along the main axis at <i>ϑ</i> = 0.2 (a) and 0.4 (b) in the absence of cell diffusion and cell-surface adhesion (<i>p</i>_div = 1, <i>ϵ</i>_cs = 0). The well and cells are represented by black and red circles, respectively.
