In the mouse embryo, oscillations in tissue-wide signalling dynamics govern pattern formation during development.
The development of an embryo into an organism is amazingly complex. It requires the coordination of many intricate processes which must be tightly controlled in time and space. Failure in any one of these processes will result in a defect in development.
In order to coordinate development, the embryo must be able to measure time. Patterns in the expressions of genes, known as genetic oscillations, form a framework for the many complex processes which happen.
