Numerical simulations for a population of microtubules after two hours of reaction time. The reaction space is of two dimensions, measures 100 μm by 100 μm, and contains approximately 4.104 microtubules. The simulations shown in A), B), C) and D) correspond to reaction times of 120, 122, 124 and 126 minutes respectively. The colour scale is proportional to microtubule concentration. Self-organisation occurs by the formation of macroscopic arrays of aligned microtubules that advance as collective fronts at a speed of 4 μm min-1. The yellow line highlights the position of one such advancing front compared to its position (indicated by the red line) at the first reaction time shown in A).
