Mechanosensory hair cells are the receptor cells of the inner ear. The best-characterized in vitro model system of mature mammalian hair cells utilizes organ cultures of utricles from adult mice. We present the dissection of the adult mouse utricle, and we demonstrate adenovirus-mediated infection of supporting cells in cultured utricles.

We present a method to isolate the adult organ of Corti as three intact cochlear turns (apex, middle, and base). We also demonstrate a procedure for immunostaining with fluorescently tagged antibodies. Together these techniques allow the study of hair cells, supporting cells, and other cell types found in the cochlea.

Primary cilia influence various signaling pathways. The mammalian cochlea is ideal for examining planar cell polarity (PCP) signaling. Cilia dysfunction affects cochlear outgrowth, cellular patterning and hair cell orientation, readouts of PCP. Our goal is to analyze PCP signaling in mouse cochlea via phenotypic analysis, immunohistochemistry and scanning electron microscopy.
FAQs
Bony labyrinth dissection depends on controlled, progressive bone removal rather than broad excavation. The approach follows the osseous contours while preserving delicate walls and recognizable landmarks, allowing the cochlea, vestibule, and semicircular canals to remain spatially interpretable. This balance matters because excessive removal can erase relationships needed to understand how inner-ear structures are organized.
Exposing the osseous labyrinth allows investigators to compare its spatial framework with the membranous labyrinth and the sensory epithelia associated with hearing and balance. This anatomical relationship helps clarify how mechanical stimuli are conveyed toward sensory regions. The resulting view connects structural organization with the functional questions central to auditory and vestibular neuroscience.
Nearby neurovascular anatomy provides essential spatial context for interpreting the inner ear within the temporal bone. Tracing these relationships during dissection can show how the labyrinth is positioned relative to structures relevant to neural pathways and surgical approaches. This context also improves comparison with imaging and supports more accurate interpretation of anatomical findings.
The procedure begins with progressive removal of bone, followed by careful exposure of the osseous walls and major labyrinthine landmarks. As the dissection advances, the cochlea, vestibule, and semicircular canals can be traced in relation to one another, while delicate boundaries are preserved. The outcome is a spatially organized view suitable for anatomical and neuroscientific interpretation.
Delicate walls, identifiable osseous landmarks, and the spatial relationships among the cochlea, vestibule, and semicircular canals should remain intact as far as possible. Preserving these features prevents the exposed anatomy from becoming a collection of isolated parts. It also supports correlation with the membranous labyrinth, sensory epithelia, and nearby neurovascular structures.
In neuroscience, this dissection supports detailed study of auditory and vestibular anatomy and provides a structural basis for investigating hearing, balance, and inner-ear disease. Researchers can use the exposed relationships to interpret imaging, understand the anatomical context of surgical approaches, and frame experimental observations about how mechanical stimuli reach sensory epithelia.
