When a fetus develops, cell division and differentiation, gene expression, cell-to-cell signaling, and morphogenesis must be carefully coordinated to occur in the correct sequence and for the proper amount of time. Failures in timing can result in congenital deformities, disabilities, and even death. For a long time, developmental biologists have sought to determine what sets the pace and directs the order of developmental events.
