This video demonstrates New culture, a method by which chick embryos are cultured outside the egg for up to 24 hr. This method enables one to study early development (primitive streak to 14 som.), a period corresponding to E7-9 in mouse. Applications of this technique include electroporation, in situ hybridization and immunohistochemistry.

2026
Mammalian and other animal-derived cell culture systems are widely used in biomedical research as New Approach Methodologies (NAMs) that reduce reliance on animal testing while enabling controlled investigation of cellular responses. These in vitro systems provide reproducible platforms for studying disease mechanisms, drug activity, toxicity, and neuronal function under defined laboratory conditions. Establishment and Maintenance of Cell Cultures To establish a culture, cells are seeded into...

We describe here a revised protocol for large-scale culture of embryonic C. elegans cells. Embryonic C. elegans cells cultured in vitro using this method, appear to differentiate and recapitulate the expression of genes in a cell specific manner. Techniques that require direct access to the cells or isolation of specific cell types from the other tissues can be applied on C. elegans cultured cells.

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
Temperature, pH, and oxygen must be regulated because each condition can influence whether cells, tissues, or microorganisms remain viable and multiply. Their effects are not considered separately from the nutrient medium or sterile environment; together, these variables create the conditions needed for consistent growth. Careful regulation therefore improves the reliability and reproducibility of biological observations.
The nutrient medium provides the immediate laboratory environment in which the introduced sample is maintained and can multiply. Its suitability depends on the biological material being studied, since cells, tissues, and microorganisms may require different supporting conditions. Selecting an appropriate medium is therefore a central step in establishing a culture that produces interpretable results.
Sterile conditions limit contamination from unwanted organisms that could interfere with the target cells, tissues, or microorganisms. Contamination may make it difficult to determine whether an observed outcome reflects the intended sample or an unintended biological influence. Maintaining sterility consequently supports both reliable growth and reproducible comparisons between experiments using the same culture approach.
By placing biological material under regulated laboratory conditions, these methods allow researchers to examine physiology, development, disease, or microbial behavior while controlling important environmental variables. This controlled setting can make biological responses easier to observe and compare than in a less regulated environment. The resulting cultures also support investigation of specific processes without requiring the entire original system.
A typical workflow begins by introducing a biological sample into a suitable nutrient medium. The culture is then maintained under regulated temperature, pH, oxygen, and sterile conditions so the target material can remain viable and multiply. Researchers monitor the resulting culture as the basis for subsequent study, comparison, treatment screening, or production of biological materials.
New culture methods can support studies of physiology, development, disease, and microbial behavior. They also create experimental systems for screening treatments, producing biological materials, and modeling complex biological processes. Because researchers can regulate culture conditions, the methods may improve experimental efficiency and reproducibility while expanding the types of biological questions that can be examined in the laboratory.
