Astrocytes have been recognized to be versatile cells participating in fundamental biological processes that are essential for normal brain development and function, and central nervous system repair. Here we present a rapid procedure to obtain pure mouse astrocyte cultures to study the biology of this major class of central nervous system cells.

Source: Creighton, B. A., et al. Visualizing and Analyzing Intracellular Transport of Organelles and Other Cargos in Astrocytes. J. Vis. Exp. (2019)This video demonstrates the visualization of intracellular cargo transport in cultured astrocytes using a fluorescent acidotropic probe that selectively labels acidic endolysosomal vesicles. Time-lapse imaging and Z-stack acquisition with a confocal microscope allow tracking of fluorescently labeled cargo throughout the three-dimensional cell volume.

2025
The video demonstrates a simple method to culture murine astrocytes in isolation from other brain cells. During culturing, by using astrocyte-specific media and inhibiting the adherence of non-astrocytic cells, the method selectively cultures astrocytes. These cultured astrocytes exhibit stellate morphology with fine processes.

Generating a Primary Culture of Astrocytes from a Rat Pup Brain

The video demonstrates a technique for culturing primary astrocytes from the rat cortex. The cortex is mechanically dissociated to obtain a homogeneous glial cell suspension, which is then plated on polypeptide-coated plates to promote selective proliferation of astrocytes. Subsequently, the astrocytes are enzymatically dissociated from the plates and transferred to fresh media, allowing the culture of pure astrocytes.

This video demonstrates establishing a neuron-astrocyte co-culture for recording neuronal network activity. Upon establishing the co-culture of motor neurons and astrocytes on a multi-electrode array (MEA) plate, the synchronous rhythmic electrical activity of the neuronal network was recorded extracellularly using the MEA.
FAQs
Enrichment can take advantage of differences in how cells adhere to treated culture surfaces and how they grow under the selected conditions. These differences help increase the relative representation of astrocytes after neural tissue has been dissociated. The resulting population supports more focused analysis of astrocyte morphology, proliferation, signaling, and other cell-specific responses.
Surface treatment, medium composition, temperature, gas availability, and nutrient supply all shape how cells attach, expand, and remain viable. Defined media and serum-containing media provide different experimental environments, so the choice should match the biological question. Controlling these variables improves reproducibility when examining growth, extracellular regulation, inflammatory signaling, or neurotransmitter handling.
Astrocyte cultures allow researchers to monitor changes in morphology and proliferation while testing functions linked to neuronal support. They can also be used to examine inflammatory signaling, neurotransmitter handling, and regulation of the extracellular environment. Because the cells grow under controlled conditions, investigators can connect a treatment or experimental variable with a specific cellular response more directly.
The culture system isolates astrocytes from the full architecture of brain tissue, making individual variables easier to control but reducing biological complexity. It can model selected cellular behaviors and interactions with neurons, yet it does not reproduce the complete tissue environment. For this reason, culture findings are most informative when interpreted alongside, rather than as replacements for, animal-model evidence.
A typical workflow begins by dissociating neural tissue mechanically or enzymatically, followed by transferring the resulting cells onto treated culture surfaces. Cells are then maintained in defined or serum-containing medium under controlled temperature, gas, and nutrient conditions. Expansion and enrichment depend on the growth and adhesion properties of the cells, after which the culture can be used for planned analyses.
This approach is useful when investigators need a controlled cellular system for testing neurotoxic compounds or examining disease-related mechanisms. Treatments can be evaluated through effects on astrocyte morphology, proliferation, inflammatory signaling, neurotransmitter handling, or neuronal interactions. Such experiments help separate astrocyte responses from other influences and can provide mechanistic evidence for broader neurobiology and pharmacology studies.
Cultured astrocytes can be examined alongside neurons to investigate how glial cells support neuronal function and influence the surrounding extracellular environment. These experiments may focus on cellular interactions, neurotransmitter handling, or responses to experimental treatments. The simplified setting helps researchers identify astrocyte contributions, while comparison with animal models is needed to assess relevance to more complex brain biology.
