This video demonstrates the isolation of cells from the sensory ganglia of mice. Ganglia are subjected to enzymatic digestion to dissolve the extracellular matrix. Single cells are then collected via filtering through a cell strainer followed by density gradient centrifugation for debris removal. Finally, washing and centrifugation are done to collect the isolated cells for future analysis.

Dorsal root ganglia (DRG) contain primary sensory neuron cell bodies and relay peripheral sensory signals to the spinal cord. This protocol describes a method for mouse DRG dissection that supports standardized isolation of structurally intact ganglia, anatomical segmental identification, intuitive guidance for novice users, and reduced procedural tissue injury.

FAQs
Preserving an isolated ganglion as an intact structure retains the arrangement of neuronal cell bodies and supporting glial cells. This organization allows investigators to examine morphology, connectivity, and signaling within a defined tissue context. Dissociation instead produces individual cells for analysis, so the choice depends on whether the experiment emphasizes tissue organization or cell-level measurements.
Microscope-guided dissection helps researchers identify the ganglion accurately, separate it from surrounding nervous tissue, and remove adjoining material with precision. These steps are important because the preparation must preserve the isolated structure or its constituent cells for downstream analysis. Careful visual handling supports more focused studies of neuronal and glial properties.
An isolated ganglion can support complementary measurements of neuronal morphology, connectivity, signaling, electrophysiology, and gene expression. Because the tissue is separated from surrounding nervous structures, researchers can investigate these properties in a defined biological context. This focused preparation helps connect cellular features with functional characteristics of sensory, autonomic, or peripheral nervous system tissue.
The workflow begins with precise dissection under a microscope to locate the ganglion. Researchers then separate it from surrounding nervous tissue and remove adjoining material. After isolation, the structure may be preserved for direct study or dissociated into individual cells. The selected endpoint determines whether later work examines tissue organization or separate neuronal and glial cells.
Dissociation is useful when experiments require access to individual neuronal or supporting glial cells rather than the intact ganglion. The resulting cells can provide material for focused analysis, cell culture, pharmacological testing, or gene expression studies. This approach changes the experimental emphasis from organized tissue relationships to properties that can be examined at the single-cell level.
Isolated ganglia provide experimental material for investigating sensory, autonomic, and other peripheral nervous system functions. Researchers can examine signaling and electrophysiology in a defined preparation, assess neuronal morphology and connectivity, or use the tissue for pharmacological testing. The same preparation can therefore connect structural observations with functional responses in specialized nervous system regions.
