Book Description
Cell-Cell Signaling in Vertebrate Development provides a comprehensive discussion of cell-cell interactions in vertebrate development and the molecular signals that mediate them. The book is divided into six parts, arranged according to major developmental phenomena demonstrated in illustrative systems derived from amphibian, avian, mammalian, and piscine sources. Part I introduces the mechanisms of gene activation in the context of early vertebrate development. Part II is concerned with cellular contacts and the induction process. Cell-cell interactions are illustrated through analyses of neurogenesis in the mouse; embryonic induction is considered in the frog and in the chick. Part III deals with cell migration and differentiation. It examines cell lineages in the frog eyebud; migration phenomena in connection with axon guidance in the embryonic rat spinal cord and mouse visual system; pathfinding by primary motoneurons; and the formation of terminal arbors in zebrafish embryos. Part IV discusses developmental processes that depend on diffusible signals and signal gradients. Part V illustrates pattern formation as exemplified in the developing chick hindbrain and in urodele limb regeneration. Part VI highlights gene expression and its regulation by transcription factors or growth factors in rodent development.

Book Description
The formation of a complex multicellular organism from a single cell is one of the most amazing processes of biology. Embryonic development is characterised by the careful regulation of cellular behaviours such that cells proliferate, migrate, differentiate and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, and on the activities of signalling pathways, which coordinate the cell interactions leading to organogenesis. The aim of the Frontiers research topic “Signalling pathways in embryonic development” has been to provide a forum for experts in cell and developmental biology to share recent advances in the field of signalling during embryonic development. Sixteen articles in a variety of formats are united in this Topic, offering a valuable collection for researchers looking for an update in the knowledge of signalling pathways operating during embryogenesis. The works, focused mainly on vertebrates, explore different aspects of this theme from cell communication to organ formation and have implications for areas as distant as evolution or pathology. Understanding developmental signalling pathways is important for several reasons. It gives us information about basic mechanisms of cell function and interactions needed for morphogenesis and organogenesis. It uncovers the basis of congenital malformations, since errors at any step of cell signalling during development are a major cause of defects. This fundamental insight gives us clues to understand the mechanisms operating in evolution that explain diversity in form and function. And finally, it allows the identification of possible causes of disease in the adult organism (such as cancer or degenerative diseases) pinpointing possible targets for therapeutic approaches.

Book Description
The Wnt/β-catenin signaling pathway is a key regulator of cell fate specification, differentiation, and growth in multiple systems throughout the animal kingdom. In vertebrate posterior neural development, Wnt/β-catenin signaling controls this complex multistep process. It initially induces the posterior regions of the nervous system, including the mid-hindbrain border, hindbrain, spinal cord and neural crest, and then subsequently fine-tunes the pattern of each region and determines the different cell fates within them. In this review, we explore the function of the Wnt/β-catenin pathway during the formation of these specific posterior neural regions. We have examined the important transcriptional targets of the Wnt/β-catenin pathway acting downstream to mediate its morphogenetic activity. Different regulatory networks are activated in different posterior neural regions, and these networks induce specific neural cell types in each region. Eludidating how each of these networks specify different cell fates is crucial for understanding the basic tenets of how Wnt morphogenetic activity induces the posterior nervous system during the earliest stages of vertebrate development.

Book Description
Cell-Cell Signaling in Development, Volume 150 covers new approaches and topics surrounding the diversity of animals, with recognized species now in the millions. Remarkably, the many distinct morphologies in the metazoan biosphere are generated by only a small number of genetically-encoded signaling systems that organize cells into patterned tissues, principally, the Wnt, Hedgehog, Bone morphogenic protein, fibroblast growth factor, Notch/Delta, and planar polarity systems whose roles orchestrating morphogenesis are widespread and evolutionarily conserved. Users will find the latest information on these elegant systems, along with conceptual links to signaling in plants and ideas that are emerging from recent progress. Presents the newest information on signaling proteins of animal development Covers the processes that make and distribute signaling proteins Includes coverage of cell-cell interactions that pattern tissues

Book Description
The book considers signaling events from the zygote embryo through to the blastocyst with relevant data from embryonic stem (ES) cells, including dialogue with the extracellular environment and with the maternal tract during the implantation process. Application of the knowledge described to improve the success of human and animal assisted conception is considered where appropriate, but the focus is largely on fundamental rather than applied cell/molecular biology, as this is the area that has historically been neglected. While the general features of metabolism during preimplantation development are well established, especially in terms of nutrient requirements, uptake and fate, remarkably little is known about early embryo signaling events, intracellular or intercellular, between individual embryos in vitro or with the female reproductive tract in vivo. This contrasts with the wealth of information on cell signaling in somatic cells and tissues, as a glance at any textbook of biochemistry illustrates. This lack of information is such that our understanding of the molecular cell biology of early embryos -- a prerequisite to defining the mechanisms which regulate development at this critical stage of the life cycle -- is seriously incomplete. This volume is the first to address this issue by describing the current state of knowledge on cell signaling during mammalian early embryo development and highlighting priority areas for research.

Book Description
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.
