This video demonstrates a method for harvesting neurons from the dorsal root ganglia (DRG). DRG from a rat's spinal column is isolated, treated with enzymes, and then mechanically dissociated to obtain a single-cell suspension. The neurons are separated from glial cells using density gradient centrifugation and cultured in a growth medium.

Direct intranuclear injection of cDNA is an effective transfection technique for post-mitotic cells. This method provides high levels of heterologous protein expression from single or multiple cDNA constructs and enables protein function to be studied in a physiologically relevant environment with a variety of single cell assays.
FAQs
After plating, individual neurons extend neurites, which are projections that support the development of neuronal connections. Under defined growth conditions, these extensions can interact with those of neighboring cells and form synaptic connections. This progression allows researchers to examine neuronal development and connectivity directly, rather than assessing these processes only within intact nervous tissue.
Defined growth conditions help researchers examine how neurons respond when environmental variables are controlled. Because the cells are accessible as individual neurons, investigators can relate changes in neurite extension, synaptic connection, electrophysiological activity, or treatment response to specific experimental conditions. This control supports more focused analysis of cellular mechanisms and signaling effects.
These cultures provide access to several connected levels of neuronal behavior. Researchers can examine development and neurite growth, observe the formation of synaptic connections, assess electrophysiological activity, and test responses to genes, signaling molecules, or experimental treatments. Considering these outcomes together helps link cellular mechanisms with changes in neuronal function.
Preparation begins by separating neurons from nervous tissue through mechanical and/or enzymatic dissociation. The resulting cells are then plated on a suitable substrate and maintained under defined growth conditions. During culture, investigators can monitor neurite extension, synaptic connection formation, electrophysiological activity, and responses to treatments or other experimental factors.
They are useful when investigators need an accessible model for examining neurotoxicity or disease-related cellular changes. Researchers can expose the cultured neurons to experimental treatments and evaluate effects on neuronal development, connectivity, electrophysiological activity, or function. The system also supports testing how particular genes or signaling molecules influence these disease-relevant responses.
Dissociated neuronal cultures can provide evidence about neuronal development, connectivity, electrophysiological activity, and responses to defined treatments. They also support analysis of cellular mechanisms, neurotoxicity, disease-related changes, and the effects of genes or signaling molecules. These outcomes make the cultures useful for connecting controlled experimental conditions with measurable changes in neuronal behavior.
