The goal of this volume is to comprehensively cover a highly readable overview on our present knowledge of the role of Notch signalling for embryology and cancer, with a focus on new findings in molecular biology. Topics that are discussed in-depth by leading researchers and clinicians range from the newest findings in cellular and molecular pathology to new concepts for prophylaxis and treatment of cancer. Experts in the field as well as scientists and health care professionals not intimately involved in these specialized areas are provided with the most significant and timely information related to these topics. It is the aim of this book to summarize essential up-to-date information for every clinician or scientist interested in the role of Notch signalling in embryology and cancer. We hope that this volume will be adopted as the standard text in this area of science and will stimulate new interest in the role of Notch signalling for embryology and cancer. We further hope that this compendium will serve as both a source for current researchers and a guide to stimulate and assist those in related disciplines to enter this exciting field of research.
