An Introduction to Working in the Hood
0 Views •
2023
Hoods are a common class of instrument, which act as a protective enclosure for various types of laboratory experiments. They serve to shield experimental samples from the environment, as well as to protect the researcher from hazardous or infectious samples. “The Hood” is a term that can include laminar flow benches, fume hoods, as well as tissue culture hoods or biosafety cabinets. All hoods operate based on the principle of laminar flow and have the same basic components, including a...

Robert M. Rioux & William A. Elliott, Pennsylvania State University, University Park, PA Fume hoods and laminar flow cabinets are engineering controls that operate under similar principles. Both use a constant flow of air to prevent contamination of the laboratory environment and its inhabitants. Fume hoods prevent hazardous substances from exiting the hood workspace, whereas laminar flow cabinets prevent contaminants from entering the cabinet workspace. Fume hoods are ventilation systems...

Histotypic Tissue Culture

2023
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.
FAQs
HEPA-filtered air helps reduce airborne particles that could enter an exposed culture, while unidirectional flow supports a more consistent clean-air environment across the workspace. This matters because cell and tissue cultures can be disrupted by contamination during open handling. Maintaining the intended airflow while working therefore supports cleaner transfers and more reproducible culture experiments.
Airflow only helps when handling practices preserve its benefit. Careful manipulation within the clean-air path helps limit exposure to airborne contamination during transfers, media changes, and seeding. For that reason, aseptic technique in a Tissue Culture Hood combines the enclosure’s filtration with controlled handling, supporting cultures used in cell biology, disease studies, and tissue engineering.
Surface disinfection reduces contamination sources on the work area, whereas an orderly workflow helps limit unnecessary disruption during culture handling. Together with filtered airflow, these practices provide complementary controls rather than relying on the hood alone. Their combined use supports more consistent media changes, cell transfers, and seeding, improving the reproducibility of biological experiments.
A careful workflow centers on disinfecting the work surface, maintaining a clean sequence of operations, and performing manipulations within the filtered airflow. The procedural goal is to prevent avoidable contamination while cells, tissues, or sterile culture materials are exposed. Applying the same disciplined approach across experiments supports reliable culture maintenance and comparison of biological results.
Researchers may use the hood during media changes, cell transfers, and seeding, when cultures or sterile materials are handled openly. These operations occur while establishing and expanding cultures, so the enclosure supports both routine maintenance and preparation for later experiments. Its use is especially relevant when contamination could compromise cell biology or tissue-based investigations.
By helping limit contamination during culture work, a Tissue Culture Hood supports experiments that depend on consistently maintained cultures. Its use is relevant to cell biology, investigations of disease mechanisms, drug-response studies, and tissue engineering. Applying aseptic technique in these settings can improve reproducibility, making experimental comparisons and interpretation of biological results more dependable.
