Excerpt from The Eggs of Mammals I should like to express my appreciation to Dr. J B. Collip, Dr. H. Selye, Dr. D. L. Thomson, and Dr. W. J Crozier for their kindness in reading the manuscript of this book before publication. Their comments have been taken advantage of in a manner for Which I, not they, em responsible. I em indebted too to Dr. F. H. A. Marshall and Mr. J ohn Ham mond of Cambridge University for encouragement and interest Which led to the undertaking of this monograph, and to my friend and collaborator Dr. E. V. Enzmann Who actively assisted in a number of the investigations herein described. The National Research Council Committee for Problems of Sex and the J osiah Macy J r. Foundation pro vided grants making possible most of my own work, and the preparation of the monograph itself is due in no small measure to their assistance. To the editors and publishers of the following journals I em indebted for permission to reprint the various tables and figures indicated in the text: the American J ournal of Anatomy, the American J ournal of Physiology, the Anatomical Record, Archives de Biologie, the Biological Bulletin, the Carnegie I nstitution of Wash ington Publications in Embryology, the J ournal of Anatomy, the J ournal of Experimental Biology, the J ournal of Experi mental M edicine, the J oumal of Experimental Zodlogy, the J ournal of M orphology, the Quarterly Review of Biology, and the Proceedings of the Royal Society.

Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.
