We present a method that describes isolation and culture of cochlear explants from embryonic mouse inner ear. We also demonstrate a method for gene transfer into cochlear explants via square-wave electroporation. The in vitro explant culture coupled with gene transfer technique enables researchers to study the effects of altering gene expression during development.

Explant culture is a technique in which living cells or tissues are removed from an embryo for continued development outside of the organism. This ex vivo approach allows researchers to manipulate and observe developing tissues in ways that are not possible in vivo. Once established, explant culture is frequently used to understand the role of genes and signaling molecules in organogenesis. This video will first introduce the basic principles of explant culture and demonstrate a protocol to...

The intricate structure of the vertebrate nervous system arises from a complex series of events involving cell differentiation, cell migration, and changes in cell morphology. Studying these processes is essential to our understanding of nervous system function as well as our ability to diagnose and treat disorders that result from abnormal development. However, neural tissues are relatively inaccessible for experimental manipulations, especially in embryonic mammals. As a result, many...

We present a protocol to culture primary murine spiral ganglion neuron explants on multi electrode arrays to study neuronal response profiles and optimize stimulation parameters. Such studies aim to improve the neuron-electrode interface of cochlear implants to benefit hearing in patients as well as the energy consumption of the device.
FAQs
Its experimental value comes from maintaining sensory and neural structures together rather than examining each cell type in isolation. Hair cells, supporting cells, and spiral ganglion neurons remain within the same isolated cochlear tissue, allowing researchers to study responses that depend on their local relationships. This organization helps connect cellular changes with broader mechanisms of hearing-related injury or development.
These cell populations provide complementary biological readouts within the same preparation. Hair cells represent sensory elements, supporting cells preserve neighboring cellular context, and spiral ganglion neurons provide a neural component for studying neuronal survival. Examining them together enables researchers to assess whether an experimental condition affects sensory cells, surrounding support, neural structures, or several components simultaneously.
Controlled conditions allow investigators to modify the environment around the isolated cochlear tissue and observe resulting biological responses. This precision supports direct testing of drugs or other treatments, as well as examination of processes associated with sensory-cell injury and neuronal survival. Because experimental variables can be adjusted in vitro, researchers can compare tissue responses under defined conditions.
The workflow begins with dissection of the cochlear tissue, followed by placement of the explant in nutrient medium. The culture is then maintained under controlled laboratory conditions that support tissue viability and preserve its cellular organization. Once established, researchers can introduce selected experimental conditions and examine effects on sensory and neural structures within the explant.
Researchers use this approach when they need to examine sensory-cell injury, neuronal survival, or responses to drugs and other treatments in a controlled preparation. The explant can reveal how experimental conditions affect multiple cochlear components while retaining their tissue relationships. These observations support investigation of hearing-loss mechanisms and evaluation of strategies aimed at protection or regeneration.
In neuroscience, the model links cochlear cellular events with neural outcomes, particularly through the preserved presence of spiral ganglion neurons alongside sensory and supporting cells. Its accessible organization makes tissue responses easier to examine while experimental conditions remain precisely adjustable. This combination helps researchers analyze development, neuronal survival, injury mechanisms, and treatment responses relevant to hearing.
