This work is designed for use as a lab manual in college-level courses in developmental biology or animal development. In each exercise, students examine gametes and developing embryos of a single species, and also perform several experiments to probe its developmental process.

This intensive manual provides students with valuable information and insights into animal development at the organismal, cellular, and subcellular levels. The book uses both descriptive and investigative approaches that emphasize techniques, key experiments, and data analysis. - Provides a broad introductory view of developmental systems - Teaches both classical embryology and modern experimental approaches - Contains seventeen laboratory exercises, written in step-by-step style - Organized with additional notes to students and preparators - Lists questions and references for each exercise - Special chapters give introductions to the scientific process, use of the microscope, and the writing of scientific papers - Illustrated with detailed line drawings

This access card code provides access to over 140 interactive videos and 300 labelled photographs instructing students on the life cycles of organisms, a laboratory manual containing challenging experiments, interactive puzzles and web links, a complete glossary with rollover definitions, study questions and a laboratory skills guide.

Amphibian embryos are supremely valuable in studies of early vertebrate development because they are large, handle easily, and can be obtained at many interesting stages. And of all the amphibians available for study, the most valuable is Xenopus laevis,which is easy to keep and ovulates at any time of year in response to simple hormone injections. Xenopusembryos have been studied for years but this is a particularly exciting time for the field. Techniques have become available very recently that permit a previously impossible degree of manipulation of gene expression in intact embryos, as well as the ability to visualize the results of such manipulation. As a result, a sophisticated new understanding of Xenopusdevelopment has emerged, which ensures the species’ continued prominent position among the organisms favored for biological investigation. This manual contains a comprehensive collection of protocols for the study of early development in Xenopusembryos. It is written by several of the field’s most prominent investigators in the light of the experience they gained as instructors in an intensive laboratory course taught at Cold Spring Harbor Laboratory since 1991. As a result it contains pointers, hints, and other technical knowledge not readily available elsewhere. This volume is essential reading for all investigators interested in the developmental and cell biology of Xenopusand vertebrates generally. Many of the techniques described here are illustrated in an accompanying set of videotapeswhich are cross-referenced to the appropriate section of the manual.

"A subject collection from Cold Spring Harbor perspectives in biology."

An essential guide for students in the life sciences, established researchers, and career counselors, this resource features discussions of job security, future trends, and potential career paths. Even those already working in the industry will find helpful information on how to take advantage of opportunities within their own companies and elsewhere.
