Researchers have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic 'barcode', they have been able to follow the cells' developmental journey and discover how the inner ear is formed in mice. The discovery could provide important insights for future treatment of hearing loss.
