Abstract:
Nearly 60 years ago, Alan Turing showed theoretically how two chemical species, termed morphogens, diffusing and reacting with each other can generate spatial patterns. Diffusion plays a crucial part in transporting chemical signals through space to establish the length scale of the pattern. When coupled to chemical reactions, mechanical processes - forces and flows generated by motor proteins - can also define length scales and provide a mechanochemical basis for morphogenesis.
