This volume summarises our present knowledge of inductive interaction during early development of various groups of chordates. Embryonic development is mainly epigenetic, that is, each embryo arises through gradual organisation and emergence of its constituent parts and not by the unfolding of preformed structures. Development as far as the full development of the 'body plan' in the embryo is described. At the beginning of development, there is only very restricted spatial diversity, but as development proceeds the interaction of the different parts leads to ever-increasing spatial complexity of the developing embryo. Interaction starts between the different cell organelles of the oocyte and the, spermatozoon; it continues without interruption between the different parts of the very early embryo and also between the different tissues and organ anlagen of the developing embryo. The new hypothesis as to the nature of the inductive interaction, which is postulated here, is in good agreement with the experimental evidence presented and opens new possibilities for fruitful research into this basic concept of embryonic development.
First published in 1943, VITAMINS AND HORMONES is the longest-running serial published by Academic Press. In the early days of the Serial, the subjects of vitamins and hormones were quite distinct. The Editorial Board now reflects expertise in the field of hormone action, vitamin action, X-ray crystal structure, physiology, and enzyme mechanisms. Under the capable and qualified editorial leadership of Dr. Gerald Litwack, VITAMINS AND HORMONES continues to publish cutting-edge reviews of interest to endocrinologists, biochemists, nutritionists, pharmacologists, cell biologists, and molecular biologists. Others interested in the structure and function of biologically active molecules like hormones and vitamins will, as always, turn to this series for comprehensive reviews by leading contributors to this and related disciplines.*Includes color illustrations*Available on ScienceDirect*Longest running series published by Academic Press *Contributions by leading international authorities

The Metastasis Group of the European Organization for Research on Treatment of Cancer (EORTC) held an International Meeting at the Royal Institution in London on April 2lst-23rd, 1980. The subject was "Clinical and Experimental Aspects of Metastasis" and these Proceedings are the record of that Meeting. Almost all of those who presented a paper or a poster have written up their contributions as chapters of the Proceedings and we have made no distinction here between posters and oral communications. The Organizers and Editors owe a considerable debt of gratitude to all the contributors who without exception presented the results of their work in a clear and concise manner that did much to reveal the essence of the complex problems central to current thinking on met astasis. Moreover most manuscripts arrived well within the deadline - a circumstance which in our experience is unusual. Of the large audience who attended the Meeting many had come from the far distant corners of the World and to them as well as to the presenters of papers the Organizers wish to express their deep appreciation.

The laws of inheritance were considered quite superficial until 1903, when the chromosome theory of heredity was established by Sutton and Boveri. The discovery of the double helix and the genetic code led to our understanding of gene structure and function. For the past quarter of a century, remarkable progress has been made in the characterization of the human genome in order to search for coherent views of genes. The unit of inheritance termed factor or gene, once upon a time thought to be a trivial an imaginary entity, is now perceived clearly as the precise unit of inheritance that has continually deluged us with amazement by its complex identity and behaviour, sometimes bypassing the u...
This volume is a revised and augmented edition of part of the book Ob"ekty Biologii Razvitiya (Animal Species for Developmental Studies) published in Rus sian in 1975 in the series of monographs Problemy Biologii Razvitiya (Problems of Developmental Biology) by Nauka Publishers, Moscow. That book described the development of organisms most frequently used in developmental biology studies. Data were provided for 22 animal species, belonging to different taxa, from protists to mammals. For the English edition we decided to divide the original book into two parts dealing with vertebrates and invertebrates, respectively. This volume deals with vertebrate species. When choosing these species, the...
