Recent advances that have enabled the growth of tissue cultures into organoids and embryoids have heightened interest as to how tissue growth is controlled during the natural processes of embryo development. It is known that the diffusion of signaling molecules called morphogens directs patterned tissue growth, but what has been harder to understand is how the gradient of morphogens from this diffusion can lead to sharply defined domains in the resulting tissue.
