This article describes methods to derive enriched populations of murine oligodendrocyte precursor cells (OPCs) in primary culture, which differentiate to produce mature oligodendrocytes (OLs). In addition, this report describes techniques to produce murine myelinating co-cultures by seeding mouse OPCs onto a neurite bed of mouse dorsal root ganglion neurons (DRGNs).

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Environmental enrichment involves objects and practices that encourage natural behaviors, improve psychological well-being, and promote better welfare in laboratory rodents. Environmental enrichment should be tailored to the...
FAQs
Selective culture conditions shift the composition of a mixed neural population by supporting neuronal representation while reducing non-neuronal cells, including glia. This changes the cellular context in which measurements are made, making neuron-associated biology and signaling easier to examine. The approach is especially useful when responses from surrounding cell types could obscure neuron-specific experimental findings.
These approaches separate or retain cells through different principles. Differential adhesion uses differences in how cells attach, density-based separation distinguishes populations by density, and immunopanning uses antibodies against cell-surface markers to retain selected cells. Choosing among them depends on which separation property best supports the desired neuronal population and the intended downstream neuroscience measurements.
In immunopanning, antibodies against cell-surface markers provide a selective means of retaining neurons from a mixed neural population. Their role is to connect cell identity with physical retention during the separation process, while non-target populations are reduced. This can help produce cultures better suited to measurements focused on neuronal signaling, development, or cellular responses.
Increasing the neuronal proportion reduces the extent to which signals from non-neuronal cells influence cellular and molecular measurements. As a result, changes observed in the culture can be interpreted more directly in relation to neuronal biology. This improved focus is important for studying synaptic function, axonal development, electrophysiology, neurotoxicity, and disease mechanisms.
A general workflow begins with a mixed neural cell population, followed by selection of an appropriate enrichment strategy. Researchers may apply selective culture conditions, differential adhesion, density-based separation, or immunopanning with cell-surface antibodies. The resulting population contains a higher proportion of neurons and can then be used for focused studies of neuronal structure, signaling, or function.
Researchers use enriched cultures when experimental outcomes depend on distinguishing neuron-specific responses from those of surrounding cell types. They are relevant for studies of synaptic function, axonal development, electrophysiology, neurotoxicity, and disease mechanisms. By reducing non-neuronal contributions, the approach supports more focused analysis of how neurons develop, communicate, and respond to experimental conditions.
Enriched cultures can support measurements related to synaptic function, axonal development, electrophysiology, neurotoxicity, and disease mechanisms. They also improve the interpretability of cellular and molecular results by concentrating the population under study around neurons. This makes the approach useful when researchers need to connect observed changes more specifically with neuronal properties or signaling.
