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 Organ Tissue Culture

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.

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species. Plant tissue culture depends on the ability of plant tissue to give rise to an entire new plant when provided with a growth medium and appropriate environment. This ability of plant cells or tissues is termed ‘totipotency.’ The fundamental steps...

Explant Culture of Neural Tissue

The intricate structure of the vertebrate nervous system arises from a complex series of events involving cell differentiation, cell migration, and changes in cell morphology. Studying these processes is essential to our understanding of nervous system function as well as our ability to diagnose and treat disorders that result from abnormal development. However, neural tissues are relatively inaccessible for experimental manipulations, especially in embryonic mammals. As a result, many...

Outcomes depend on keeping several conditions coordinated rather than changing one factor in isolation. Aseptic handling protects the culture environment, while nutrient medium supports maintenance or multiplication. Temperature, pH, light, and gas exchange further influence how the material behaves. Controlling these variables helps distinguish biological responses from variation caused by laboratory conditions.
Periodic subculturing moves viable cells, tissues, or plant organs onto fresh medium as available nutrients are depleted. This transfer renews the conditions needed for continued maintenance or multiplication and provides a controlled point for monitoring viability. Because the protocol specifies how material is transferred, repeated culture can produce more consistent samples across experimental stages.
By regulating the culture environment, a protocol can provide a reproducible setting for examining whether cells, tissues, or plant organs maintain their state or undergo developmental change. Controlled conditions reduce unwanted variation, allowing researchers to relate observed differences to the experimental design. This makes tissue culture useful for cell and developmental studies and tissue engineering.
Researchers begin with aseptic handling, place the biological material in a nutrient medium, and regulate temperature, pH, light, and gas exchange. They then monitor the culture and periodically transfer viable material to fresh medium when nutrients are depleted. Keeping these stages standardized supports maintenance, multiplication, or differentiation while preserving control over experimental conditions.
Tissue culture protocols support several distinct biological goals, including cell and developmental studies, plant propagation, disease modeling, drug testing, and tissue engineering. The research goal determines whether investigators emphasize maintenance, multiplication, or differentiation. Across these uses, controlled culture conditions help preserve biological material and generate samples that can be compared more reliably.
In disease modeling and drug testing, standardized culture conditions help researchers work with preserved biological material and produce consistent samples. That consistency is important when comparing experimental observations across cultures, because differences are less likely to arise solely from changing temperature, pH, nutrient availability, or gas exchange. The protocol therefore supports controlled biological comparisons.
