One key to successful investigation of microglial biology is the preservation of microglial immunofunction ex vivo during isolation from CNS tissue. Isolating microglia via rotary shaking results in highly pure and immunofunctional cell cultures as assessed by fluorescent imaging, immunocytochemistry, and ELISA following microglia activation with the proinflammatory stimuli lipopolysaccharide (LPS) and Pam3CSK4 (Pam).

The ventricular cerebrospinal fluid (CSF) bathes the neuroepithelial and cerebral cortical progenitor cells during early brain development in the embryo. Here we describe the method developed to isolate ventricular CSF from rodent embryos of different ages in order to investigate its biological function. In addition, we demonstrate our cerebral cortical explant dissection and culture technique that allows for explant growth with minimal volumes of culture medium or CSF.

This video shows a procedure for generating neuronal cultures from late embryo and early postnatal mouse cortex. These cultures can be used for immunocytochemistry, biochemistry, electrophysiology, calcium and sodium imaging and provide a platform to study the neuronal development of transgenic animals that carry a postnatal lethal gene mutation.
FAQs
Natural boundaries provide planes where the outer cortical or rind region can be separated from adjacent layers with less disruption. Careful dissection, peeling, or other mechanical separation follows these interfaces rather than cutting indiscriminately through the specimen. This approach helps preserve the organization of the collected tissue and supports more reliable comparisons among samples.
Damage can alter the structure and physiological condition of the isolated material, while contamination from neighboring layers can introduce signals that do not belong to the rind. Limiting both problems improves the defined nature of the sample. As a result, microscopic, biochemical, or physiological findings can be interpreted more specifically as properties of the collected cortical region.
The separated tissue can be examined for cellular organization, composition, and transport functions, as well as responses to environmental conditions. These measurements connect features within the rind to broader organ behavior. Using a defined tissue region also allows investigators to distinguish changes associated with the cortex from changes that might originate in adjacent layers.
Isolated rind samples can be compared across developmental stages, experimental treatments, or environmental stresses. Because the analysis focuses on a particular tissue region, observed differences can be related more directly to changes within that region. This design helps link structural or functional variation in the rind with differences in whole-organ performance under the conditions being studied.
A typical workflow begins by exposing the relevant outer region, identifying the boundary between the rind and neighboring tissue, and separating the layer through careful dissection, peeling, or mechanical handling. The collected material is then retained as a defined sample for microscopy, biochemical analysis, or physiological testing. Throughout the workflow, minimizing damage and carryover remains essential.
Researchers may choose the isolated region when they need measurements specific to the outer cortical layer rather than an average across the entire specimen. This is useful for investigating cellular organization, composition, transport, or environmental responses in that tissue. The approach also supports comparisons between defined samples, including different developmental stages or experimental treatments.
