Infos

This book provides a practical guide to experimental methods for studying the development invertebrate deuterostomes as animal model systems. The chapters provide detailed experimental protocols that cover a broad range of topics in modern experimental methods. Topics covered range from rearing embryos to the care of adult animals, while also presenting the basic experimental methods including light and electron microscopy, used to study gene expression, transgenics, reverse genetics, and genomic approaches.

* Covers a wide range of methods, from classical embryology through modern genomics
* Discusses animals related to vertebrates, providing a valuable evolutionary perspective
* Includes a practical guide to the use of sea urchins in the teaching laboratory
