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.

This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Fertilization Mechanisms in Man and Mammals

Fertilization in mammals normally occUrs within the oviduct, where it is relatively inaccessible to study. However, as a result of painstaking research, most of it carried out over the last five years, this barrier to experimentation has been largely overcome by the development of in vitro fertilization techniques for at least 11 different species, including man. The result has been a rapid increase in our knowledge of the physiological and bio chemical mechanisms involved in the fertilization process. The aim of this book, which is an extension of my recent review of cell surface interactions in fertilization (Gwatkin, 1976), is to present a brief, but well documented, account of the new knowledge that has been attained. Although this book deals with mammalian fertilization mechanisms, I have included some recent experiments on am phibian and invertebrate gametes to supplement the mammalian picture. This information is particularly valuable as the rela tively large number of eggs available from these lower forms has advanced our knowledge of certain fertilization mechanisms beyond what is known in mammals. However, in the interest of brevity, I have omitted details of morphology and minor varia tions between species. For these, and other aspects not covered here, the reader is referred to the books of Austin (1965, 1968), vii viii PREFACE Austin and Short (1972), Metz and Monroy (1969), Monroy (1965), Lord Rothschild (1956a), and Zamboni (l971a).

The Fertilization Response of the Egg is the third and final volume of the Biology of Fertilization which provides a detailed discussion of the responses of the egg to the fertilizing sperm, collectively called as the activation of the egg. It is an anthology of physiological articles written by biology and physiology professionals. The book is divided into 12 chapters, half of which focused on the sea urchin egg fertilization, as it is the most studied form. The first two chapters cover the discussions on the first visible egg responses to fertilization and the formation of the fertilization membrane. The following chapter describes the relationship of sperm entry into the amphibian egg and the establishment of the symmetry of the embryo. Other chapters focus on the electrical and ionic changes of the egg plasma membrane and cytoplasm. The remaining parts of the book describe the synthetic activities in the egg that are initiated during fertilization. These include description of DNA and maternal RNA syntheses, nuclear-cytoplasm interactions, protein synthesis during oogenesis and early embryogenesis, and the expression of maternal messenger RNA. The book is an excellent reference for undergraduate and graduate biology students, specifically in physiology, embryogenesis, and developmental biology. It can also be an invaluable source of information for lecturers and professionals in biology.

This valuable reference work provides a synthesis of the latest knowledge about the acrosomatic reaction of human sperm. The acrosomatic reaction, which is a fundamental step in the process of fertilisation, is examined on both the fundamental and clinical levels. Three very recent aspects are also dealt with: what happens to the acrosome during intracytoplasmic microinjections, the usefulness of screening spermatozoa that have completed their acrosomatic reaction, and the development of contraception by a vaccine that targets one of the proteins of the acrosome. International Symposium, Collioure, France, September 1995.
