Sample photographDuring development of the mammalian inner ear, specification of cells to form distinct sensory structures for hearing is known to depend on two important signaling molecules called Shh and Wnt.

Earlier research showed that Shh was critical for the development of the auditory cavity or sac into the cochlea for hearing, but little was known about what signaled the development of the vestibular organs necessary for balance.
