From the hairs on our arms to the microscopic sensory structures of the inner ear, many tissues in the body are built with a clear sense of direction. To build these structures throughout development, individual cells must establish which way they are facing—and coordinate that orientation with cells around them. If they get this wrong, tissues may fail to form, form improperly or fail to function.

DNA recording system reveals how a single cell becomes a body

Scientists have traced the development of a mouse embryo from its first two cells to the formation of organs, using a remarkable DNA recording system that reveals the family history of individual cells. Their findings uncover how different cell types emerge on their own schedules
