Tuning into cell signals that tell where sensory organs will form inside the ear

Researchers have tracked a cell-to-cell pathway that designates the future location of the ear's sensory organs in embryonic mice. The scientists succeeded in activating this signal more widely across the embronic tissue that forms the inner ear. Patches of sensory structures began growing in spots where they don't normally appear. The results suggest an avenue for further investigation in restoring hearing loss and correcting balance problems from nerve damage in the inner ear.
