We describe a method to prepare organotypic hippocampal slices that can be easily adapted to other brain regions. Brain slices are laid on porous membranes and culture media is allowed to form an interface. This method preserves the gross architecture of the hippocampus for up to 2 weeks in culture.

This video article demonstrates the establishment of organotypic retinal wholemount cultures and a cytospin procedure for analysis of exogenously induced effects. Organotypic retinal wholemount cultures mimic the in vivo situation and significantly facilitate the accessibility of murine retinas for experimental manipulations while circumventing the disadvantages of classical murine animal models.

An in vitro method to mimic in vivo epithelial differentiation is described. Many viruses target epithelial cells as part of their viral life cycle, and this method provides a means of examining virus:host interactions that more closely resembles that which occurs in vivo. This technique can be used with primary keratinocytes, established cell lines, as well as normal or diseased biopsy tissue.

Here we describe a technique for studying hippocampal postnatal neurogenesis using the organotypic slice culture technique. This method allows for in vitro manipulation of adult neurogenesis and allows for the direct application of pharmacological agents to the cultured hippocampus.
FAQs
The air–liquid interface supports tissue slices or explants by exposing them to gases while allowing nutrients to diffuse from the culture medium through a porous membrane. This arrangement helps maintain neural tissue under controlled ex vivo conditions without removing neurons, glia, and connected circuits from their local tissue environment. It therefore supports experiments that require both accessibility and preserved organization.
Maintaining three-dimensional architecture preserves spatial relationships among neurons, glia, and neural circuits. Those relationships allow researchers to examine processes such as synaptic plasticity, development, neurodegeneration, and injury responses in a setting that retains local cellular interactions. The resulting observations can provide more biologically relevant information than experiments that examine neural components without their original tissue organization.
Organotypic Culture combines experimental control with biological features retained from intact neural tissue. Unlike highly simplified cell-based systems, the slices or explants preserve cellular organization and local interactions, while still allowing researchers to manipulate culture conditions, apply pharmacological treatments, and perform imaging. This balance makes the approach useful when isolated cellular behavior alone does not capture circuit-level responses.
The preparation must retain the tissue architecture, cellular organization, and local interactions that connect neurons, glia, and neural circuits. A porous membrane and culture medium provide the physical and nutritional conditions described for maintaining the explant or slice, while gas exposure supports diffusion at the air–liquid interface. Together, these features enable structural preservation and functional studies ex vivo.
A basic workflow places a neural tissue slice or explant onto a porous membrane and positions it at an air–liquid interface with culture medium available for diffusion. The preparation is then maintained ex vivo so that nutrients and gases can reach the tissue while its organization remains connected. This setup creates a controlled platform for subsequent imaging, treatment, or circuit studies.
Researchers can choose this approach to investigate neural development, synaptic plasticity, neurodegeneration, injury responses, or circuit function. It is especially useful when experiments need controlled access to living tissue while retaining relevant cellular relationships. The same platform can also support pharmacological testing and imaging, allowing treatments or structural and functional changes to be examined in a connected neural preparation.
Imaging can document structural or functional changes within preserved neural tissue, while pharmacological testing can examine how controlled treatments affect neurons, glia, synaptic processes, or circuit behavior. Because the tissue remains organized, these approaches can connect experimental manipulation with responses occurring across local neural interactions. The system therefore supports evaluation of both cellular effects and broader circuit-level outcomes.
