Here we provide a protocol for culturing rat cortical neurons in the presence of a glial feeder layer. The cultured neurons establish polarity and create synapses, and can be separated from the glia for use in various applications, such as electrophysiology, calcium imaging, cell survival assays, immunocytochemistry, and RNA/DNA/protein isolation.

This protocol outlines the steps required to dissect, transfect via electroporation and culture mouse hippocampal and cortical neurons. Short-term cultures may be used for studies of axon outgrowth and guidance, while long-term cultures can be used for studies of synaptogenesis and dendritic spine analysis.

In utero electroporation is a valuable method for transfecting neuronal progenitor cells in vivo. Depending upon the placement of the electrodes and the developmental timepoint of electroporation, certain subsets of cortical cells can be targeted. Targeted cells can then be analyzed in vivo or in vitro for effects of genetic alteration.

This protocol describes a microglia-neuronal co-culture established from primary neuronal cells isolated from mouse embryos at embryonic days 15-16 and primary microglia generated from the brains of neonatal mice at post-natal days 1-2.
FAQs
Controlled culture conditions must support several linked outcomes: cell attachment, neuronal survival, neurite extension, and synapse formation. These features determine whether the cultured cells can provide a meaningful model of neuronal structure and function. Maintaining those outcomes allows researchers to examine development, signaling, and communication rather than studying isolated cells without organized neuronal behavior.
Primary cortical neurons preserve many properties of mature neural tissue, giving them greater biological relevance for studies of neuronal behavior. Cell lines remain useful complementary models, but they may not represent tissue-derived characteristics in the same way. This distinction matters when researchers investigate development, electrophysiological signaling, synaptic communication, disease mechanisms, or responses to experimental treatments.
Their ability to extend neurites and form synapses creates a cellular context for examining how neurons connect and communicate. Researchers can then investigate electrophysiological signaling alongside synaptic communication, linking cellular structure with functional behavior. These features also make the cultures useful for studying how neuronal networks respond during development, injury, or treatment.
Preparation begins with cortical tissue isolation, followed by dissociation into individual cells. The cells are then maintained in culture under controlled conditions that encourage attachment, survival, neurite extension, and synapse formation. Once these properties are supported, the culture can serve as an experimental system for examining neuronal development, signaling, communication, or treatment responses.
Researchers may choose this culture system when they need a model that remains closely related to cerebral cortical tissue while permitting controlled laboratory experiments. It is relevant to investigations of neurobiology, disease mechanisms, neuronal injury, and potential therapeutics. The approach is especially informative when cellular structure, signaling, and responses to experimental treatments must be examined together.
Primary cortical neuron cultures can provide information about neuronal structure through neurite extension and synapse formation, as well as functional information from electrophysiological signaling and synaptic communication. They also support analysis of developmental processes and cellular responses to injury or experimental treatments. Together, these outcomes connect observable neuronal properties with broader questions in neurobiology and therapeutic research.
