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.

Key Features

* 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


Developmental biologists and cell biologists.

About the Serial Volume Editors

Charles Ettensohn

Dr. Charles A. Ettensohn, Professor of Biological Sciences at Carnegie Mellon University (Pittsburgh, USA), is one of the world’s leading researchers using sea urchins and other echinoderms as experimental models to study mechanisms of embryogenesis. Over the past 30 years his laboratory has made major contributions to developmental biology. His current work focuses on the architecture, function, and evolution of developmental gene regulatory networks, with the overarching goal of elucidating the genetic control of anatomy. Dr. Ettensohn has authored more than 80 peer-reviewed articles, co-organized multiple international conferences on echinoderm development, and currently serves on the editorial boards of BMC Genomics, Genesis, and Faculty of 1000 (Biology).
