A simple method to record extracellular field potentials in the larval zebrafish forebrain is described. The method provides a robust in vivo read-out of seizure-like activity. This technique can be used with genetically modified zebrafish larvae carrying epilepsy-related genes or seizures evoked by administration of convulsant drugs.

Histotypic Tissue Culture

Although two-dimensional tissue culture has been common for some time, cells behave more realistically in a three-dimensional culture, and more closely mimics native tissue. This video introduces histotypic tissue culture, where the growth and propagation of one cell line is done in an engineered three-dimensional matrix to reach high cell density. Here, we show the harvesting of cells from donor tissue, followed by cell culture on an engineered construct.

Whole organs can be cultured ex vivo using specialized bioreactors with the goal of repairing or replacing entire organs. This method uses a donor organ that is stripped of all cells, leaving behind the three-dimensional structure, which is then repopulated with new cells. This video demonstrates the whole organ culture of lungs and shows how a dynamic culture that mimics the mechanical stimulation in the body is needed to induce native tissue properties.
FAQs
Maintaining forebrain tissue in an organized piece preserves cellular interactions that can be disrupted when cells are separated. This makes it possible to examine neuronal migration, differentiation, and connectivity in relation to surrounding cells and tissue structure. The resulting observations can connect individual cellular behaviors with broader changes in tissue organization.
Developing and mature tissue represent different biological states, so they support different questions about forebrain organization. Developing samples can reveal processes such as neuronal development, migration, and differentiation, whereas mature samples can help examine established connectivity or responses to treatments. Selecting the tissue stage therefore aligns the culture with the process under investigation.
Temperature, gas exchange, and nutrient medium composition are central variables because they determine how well the tissue can be maintained outside the organism. Changes in these conditions may alter cellular behavior or tissue responses, making experimental interpretation difficult. Researchers regulate them to create a consistent environment for comparing development, connectivity, or treatment effects.
The culture provides more experimental control than an intact organism while retaining more tissue-level organization than isolated cells. Researchers can regulate the surrounding environment and apply treatments directly, yet still examine interactions among cells within forebrain tissue. This intermediate setting helps link cellular mechanisms to tissue outcomes without the full complexity of the living organism.
A typical workflow begins by selecting and dissecting the relevant forebrain region from developing or mature tissue. The sample is then placed in a nutrient-supported culture environment, where temperature, gas exchange, and medium composition are regulated. Maintaining these conditions allows researchers to study tissue behavior and responses during the experimental period.
Forebrain cultures can provide direct observations of neuronal development, cell migration, differentiation, and connectivity under controlled conditions. They also allow researchers to examine how forebrain tissue responds to experimental treatments. These outcomes support studies of brain organization, neurodevelopmental disorders, injury, and neurotoxicology by connecting cellular changes with tissue-level effects.
