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.

This video demonstrates the preparation of primary neuronal cultures from midgastrula stage Drosophila embryos. Views of live cultures show cells 1 hour after plating and differentiated neurons after 2 days of growth in a bicarbonate-based defined medium. The neurons are electrically excitable and form synaptic connections.
FAQs
Culture medium supplies nutrients while maintaining the temperature, pH, osmotic conditions, and gas levels needed for continued development. These variables act together rather than independently: imbalance can affect cell division, genome activation, compaction, or blastocyst formation. For this reason, controlled conditions are central to interpreting whether an embryo remains viable and reaches later developmental stages.
These conditions help preserve the chemical environment required by early embryos outside the organism. pH supports suitable biochemical conditions, osmotic balance helps maintain cellular conditions, and gas levels contribute to an appropriate culture environment. Maintaining all three allows researchers to examine development under controlled conditions instead of confusing environmental effects with intrinsic differences among embryos.
Embryo culture can support observation of sequential events including cell division, genome activation, compaction, and, in suitable systems, blastocyst formation. Tracking these changes provides a developmental timeline that can be related to cell fate, gene function, or embryo viability. The resulting observations help connect early cellular behavior with later developmental outcomes.
Because embryos develop under defined laboratory conditions, researchers can examine how environmental conditions influence early development while observing cellular changes directly. Outcomes such as altered division, compaction, or viability can then be considered alongside the controlled culture environment. This makes the method useful for studying interactions between external conditions and intrinsic developmental processes.
A basic workflow begins with fertilized eggs or early embryos and places them in a balanced culture medium. Researchers maintain suitable temperature, pH, osmotic conditions, and gas levels, then observe development as embryos divide and may undergo genome activation and compaction. In suitable systems, monitoring continues through blastocyst formation and assessment of developmental outcomes.
Researchers use the method to investigate early development, cell fate, gene function, and environmental effects on embryonic viability. It provides access to developmental stages that can be observed outside the organism under controlled conditions. This combination of experimental control and direct observation makes embryo culture relevant to both basic developmental biology and studies of embryo quality.
In assisted reproduction, embryo culture supports embryo assessment and provides a setting for development before related procedures such as cryopreservation. In animal biotechnology, it contributes to producing genetically modified animals. These uses extend the method beyond observation, linking controlled early development with clinical applications and agricultural research while retaining a connection to developmental biology.
