Description

Advances in Morphogenesis, Volume 4 covers the significant advances in various aspects of morphogenesis. This volume is composed of six chapters that specifically consider the biological aspects of cell growth and development. The opening chapter describes the techniques for cell nuclei transplantation in different organisms. The next chapter surveys the features of the unicellular desmid genus Micrasterias and its application as a model system to delineate morphogenesis. Other chapters discuss the functional problems in corneal development and the regeneration in lower plants and annelids. The last chapter provides a summary of the biological aspects of the hen's egg yolk embryogenesis. This book is directed primarily to developmental biologists.
