Single-cell electroporation (SCE) is a specialized technique allowing delivery of DNA or other macromolecules into individual cells within intact tissue, including in vivo preparations. Here we detail the procedure for SCE of a fluorescent dye or plasmid DNA into neurons within the intact brain of the Xenopus laevis tadpole.

Optogenetic approaches are widely used to manipulate neural activity and assess the consequences for brain function. Here, a technique is outlined that upon in vivo expression of the optical activator Channelrhodopsin, allows for ex vivo analysis of synaptic properties of specific long range and local neural connections in fear-related circuits.

Here, we describe a method for isolation, culture and manipulation of mouse embryonic pancreas. This represents an excellent ex vivo system for studying various aspects of pancreatic development, including morphogenesis, differentiation and growth. Pancreatic bud explants can be cultured for several days and used in a range of different applications, including whole-mount immunofluorescence and live imaging.

Developmental studies in the mouse are hampered by the inaccessibility of the embryo during gestation. To promote the long-term culture of the embryonic heart at late stages of gestation, we developed a protocol in which the excised heart is cultured in a semi-solid, dilute Matrigel.
FAQs
Maintaining cellular interactions is central to the model’s usefulness. Nutrient-supported media provide the conditions needed to sustain brain tissue, while regulated temperature, oxygenation, and pH help preserve neural activity. Together, these factors allow researchers to examine synaptic signaling and related cellular responses in tissue that retains important relationships among neural components.
These variables determine whether cultured tissue can remain functionally useful during an experiment. Temperature, oxygenation, and pH must be regulated alongside nutrient support because changes in the culture environment can affect tissue maintenance and neural activity. Controlling them gives researchers a more consistent setting for comparing synaptic, developmental, injury-related, or disease-related responses.
The approach reduces the complexity of whole-animal experiments while retaining access to brain tissue and its cellular interactions. Researchers can investigate neural structure, function, and treatment responses directly under controlled laboratory conditions. This focused setting supports experiments that require closer observation of tissue-level changes without the full biological complexity of an intact organism.
Researchers place either intact brain tissue or brain slices into nutrient-supported culture media, then maintain the preparation under regulated laboratory conditions. Temperature, oxygenation, and pH are controlled to support tissue maintenance and neural activity. Once the culture is established, investigators can examine structure, signaling, or cellular responses to an experimental treatment.
This model is useful when investigators need direct access to neural tissue for studying synaptic signaling, neurodevelopment, brain injury, or disease-related changes. It also supports evaluation of how cells respond to drugs, genetic manipulation, and other treatments. The controlled setting helps connect an intervention with observable changes in neural structure or function.
Ex vivo brain cultures can reveal cellular responses to drugs, genetic manipulation, and other experimental treatments while preserving relevant neural interactions. Researchers may assess effects on synaptic signaling, neural activity, or changes associated with development, injury, and disease. These observations help characterize treatment-related responses before interpreting them within the broader complexity of neuroscience.
