Comparison between experimental and model patterns. (a) Cultured embryonic mouse skin, stained for a marker of developing follicles (purple foci). Note the clear lines of foci aligned parallel to the cut tissue edge. (b) Blow-up of the dashed square in (a). (c) Simulation of equations (4.1) to (4.4). The right-hand side boundary is set to be ‘lossy’, with components of the reaction–diffusion model assumed to flow across the tissue edge boundary, with zero-flux conditions on the remaining three. Simulations were performed using parameters drawn from set 1 of table 1, except and solved on a square field of dimension 3 × 3. For experimental details, see the study of Mou et al. [26].
