Oscillatory dynamics are tissue-dependent and robust to growth. a Numerical solution of model (1)–(4a) on a regular lattice of growing cells with oscillatory parameters, see Appendix Tables 2 and 3, and zero-flux boundary conditions. Oscillatory single-cell spots are now joined by four-cell spots which also have oscillatory dynamics. b Numerical solution of model (1)–(3) on a regular lattice of cells, with zero-flux boundary conditions. Oscillatory parameters have been set for cells (5,4) and (5,7); all other cells have standard parameter values, see Appendix Tables 2 and 3. For modified oscillatory cells, oscillatory dynamics are not preserved (Color figure online)
