The chicken embryo (Gallus gallus domesticus) provides an economical and accessible model for developmental biology research. Chicks develop rapidly and are amenable to genetic and physiological manipulations, allowing researchers to investigate developmental pathways down to the cell and molecular levels. This video review of chick development begins by describing the process of egg fertilization and formation within the chicken reproductive tract. Next, the most commonly used chick staging...

An Introduction to the Chick: Gallus gallus domesticus

The chicken embryo (Gallus gallus domesticus) is an extremely valuable model organism for research in developmental biology, in part because most of their development takes place within an egg that is incubated outside of the mother. As a result, early developmental stages can be accessed, visualized and manipulated by simply creating a small hole in the eggshell. Since billions of chickens are raised worldwide for meat and egg production, scientists can easily and economically acquire large...

Chicks (Gallus gallus domesticus) are a valuable research tool, not only for studying important concepts in vertebrate development, neuroscience, and tumor biology, but also as an efficient system in which to propagate viruses. Although eggs can be purchased from external suppliers and working with chicks requires very little specialized equipment, an understanding of proper handling procedures is required for normal embryo development. This video will provide an overview of egg handling...

Chick ex ovo Culture

2023
One strength of the chicken (Gallus gallus domesticus) as a model organism for developmental biology is that the embryo develops outside the female and is easily accessible for experimental manipulation. Many techniques allow scientists to examine chicken embryos inside the eggshell (in ovo), but embryonic access can be limited at later stages of development. Fortunately, chicks can also be cultured ex ovo, or outside of the eggshell. The major advantage to ex ovo culture is greater access to...
FAQs
Donor identity is determined through species-specific cellular features that differentiate quail cells from chick cells within the developing embryo. This distinction lets investigators follow transplanted cells after they migrate, proliferate, or differentiate. As a result, researchers can connect an embryonic region at the time of transplantation with the tissues or structures it later contributes to.
Matching developmental stages helps place donor tissue into a host environment with comparable patterning signals and developmental potential. This makes the observed behavior more interpretable because differences in cell movement or differentiation are less likely to reflect a major timing mismatch. Staged transplantation therefore supports clearer analysis of tissue interactions and embryonic pattern formation.
They can show where neural crest cells migrate and which developing structures receive their contributions. Tracking these cells links their original embryonic location with later anatomical outcomes, providing evidence about lineage relationships and differentiation. This makes the system especially useful for examining how cell movement contributes to the formation and organization of embryonic tissues.
A transplanted region can be followed within a different embryonic environment, allowing researchers to examine both its own developmental contribution and its interaction with surrounding host tissues. Observing whether donor cells migrate, proliferate, or differentiate in that context provides evidence about intrinsic lineage relationships as well as signals associated with embryonic patterning and organ formation.
Researchers first select a defined region from a quail embryo and identify a similarly staged chick embryo as the host. They then transplant the quail region into the corresponding embryonic location and allow development to continue. Later analysis uses species-specific cellular features to locate donor cells and determine their migration, proliferation, differentiation, and tissue contributions.
Analysis can identify the destinations of transplanted cells, the structures they help form, and their relationships with neighboring host tissues. These observations provide evidence for cell fate, lineage relationships, migration routes, and tissue communication. In biology, the findings help explain how embryonic regions coordinate organ formation and establish developmental patterning.
