The past decade has seen an explosion in our understanding of the factors regulating cell proliferation and differentiation. One of the most exciting advances has been the recognition of the pivotal role of the peptide growth factors in these processes. The insulin-like growth factors, discovered in 1958 by Salmon and Daughaday, are now among the best characterized growth factors. This comprehensive work describes the recent advances in knowledge of their receptors and binding proteins together with their purification and cloning. This provides exciting insights into the role of these factors in the physiology of normal growth, embryonic development and areas of pathology such as wound healing and cancer. In this book an international group of contributors reviews the most up-to-date information on all aspects of the insulin-like growth factors, and critically discusses models for IGF action in their own systems. The book is a valuable source of information and ideas for researchers, and an accessible introduction to the subject for students and clinicians.
