Using chicken embryos for teratology studies.

ABSTRACT

This unit describes methods for injecting, incubating, handling and analyzing domestic chicken embryos used in teratology studies. It also includes a discussion of caveats and special handling issues as well as some discussion of statistical analyses that differentiate working with chicken embryos from working with clutches of eggs or litters of pups. As an example of potential data, preliminary data from a study of abnormalities in early embryos and hatchling chicks exposed to chlordane are presented.
