Analysis of vestibular hair cell function is complicated by their location deep within the hardest part of the skull, the petrous temporal bone. Most functional hair cell studies have used acutely isolated hair cells. Here we describe a semi-intact preparation of mouse vestibular epithelium for electrophysiological and two-photon microscopy studies.

Multielectrode array (MEA) recordings provide a method for studying the electrical activity of large populations of neurons. Here, we present the details of a MEA preparation to record from the mouse vomeronasal epithelium while simultaneously stimulating the tissue.
FAQs
Enzymatic digestion loosens cell-cell and cell-matrix connections, while mechanical dissociation helps separate the loosened tissue into individual epithelial cells or smaller groups. Using both approaches supports more complete separation than relying on either process alone. The balance is important because the method must release cells while preserving viability and characteristic markers needed for culture, examination, or analysis.
Viable epithelial cells remain suitable for downstream studies of cellular behavior, barrier function, regeneration, infection, and responses to drugs or environmental conditions. If isolation disrupts cells excessively, the resulting material may no longer represent epithelial physiology accurately. Maintaining viability therefore improves the usefulness of isolated cells for culture-based experiments and for connecting cellular responses with tissue-level processes.
These connections hold epithelial cells within their tissue organization and must be loosened before the cells can be separated. Enzymatic digestion targets this structural linkage, while careful dissection helps limit contamination from surrounding tissues. Controlled disruption allows researchers to obtain epithelial material that can be studied independently without unnecessarily losing the markers and properties that identify its tissue origin.
A typical workflow begins with careful tissue dissection to separate the epithelial region from surrounding tissue. Enzymatic digestion then loosens cell-cell and cell-matrix attachments, followed by mechanical dissociation to produce separated cells or tissue fragments. The isolated material can subsequently be examined, cultured, or analyzed, depending on the research question and the properties that need to be measured.
Researchers use isolated epithelial cells to investigate barrier function, tissue development, regeneration, infection, and disease-related changes. The cells can also provide models for testing responses to drugs or environmental conditions. Because isolation permits epithelial material to be examined independently, it helps distinguish cellular behavior from effects produced by the surrounding tissue environment.
The method separates epithelial material from its original tissue context while retaining cellular features that can be examined in controlled settings. Researchers can then compare observations of isolated cells with the organization and function of the source tissue. This relationship is especially useful for studying epithelial physiology, including how tissue structure relates to barrier properties, development, regeneration, and disease-associated changes.
