Turing's next steps: the mechanochemical basis of morphogenesis

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.
