Download or read book Maternal Control of Development in Vertebrates written by Florence Louise Marlow. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Vertebrate Development by : Francisco Pelegri

Download or read book Vertebrate Development written by Francisco Pelegri. This book was released on 2016-12-13. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of topics describing the earliest steps of fertilization, from egg activation and fertilization to the activation of the zygotic genome, in various studied vertebrate model systems. The contribution of maternal and paternal factors and their role in the early embryo as parental DNA becomes modified and embryonic genes become activated is fundamental to the initiation of embryogenesis in all animal systems. It can be argued that this is a unique developmental period, when information from the parents is compressed to direct the development of the body plan of the entire organism, a process of astounding simplicity, elegance and beauty. In addition to their fundamental scientific interest, many frontiers of biomedicine, such as reproductive biology, stem cells and reprogramming, and the understanding of intergenerational diseases, depend on advances in our knowledge of these early processes. Vertebrate Development: Maternal to Zygotic Control brings together chapters from experts in various disciplines describing the latest advances related to this important developmental transition. Each chapter is a synthesis of knowledge relevant to all vertebrates, with details on specific systems as well as comparisons between the various studied vertebrate models. The editorial expertise encompasses the fields of major vertebrate model systems (mammalian, amphibian and teleost) ensuring a balanced approach to various topics. This unique book—with its combination of in-depth and up-to-date basic research, inter-species comprehensiveness and emphasis on the very early stages of animal development—is essential for research scientists studying vertebrate development, as well as being a valuable resource for college educators teaching advanced courses in developmental biology.

Download or read book Scientific Frontiers in Developmental Toxicology and Risk Assessment written by National Research Council. This book was released on 2000-11-21. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.
