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. Table of Contents: Introduction / Making the Neural Rear / Wnt Morphogenetic Activity in Neural Posterior Induction / Induction of the Midbrain-Hindbrain Border / Induction of the Hindbrain / Induction of the Spinal Cord / Downstream of Wnt: Hindbrain or Spinal Cord? / Neural Crest Induction / Anti-Wnt Anterior Determinants / The Role of Mesoderm and Specific Wnt Ligands in Neural Patterning / Concluding Remarks / References

Book Description
Wnt genes code for a family of secreted glycoproteins which fulfil important functions during the development of vertebrates and invertebrates. Wnts regulate as different aspects as differentiation, proliferation, cell migration, and cell polarity. Wnt proteins are able to activate different intracellular signaling cascades. This book describes different aspects of Wnt signaling during development of different species like the mouse, Xenopus, chicken, C. elegans or Drosophila and in different cellular contexts like heart formation or limb bud patterning. By doing such, this book provides, for the first time in printed form, an overview of the function of Wnt proteins during development. This book will be of interest to all professionals in the field of Wnt signaling, signal transduction or animal development.

Book Description
This volume explores the various facets of planaria as a biomedical model system and discusses techniques used to study the fascinating biology of these animals. The chapters in this book are divided into two parts: Part One looks at the biodiversity of planarian species, the molecular orchestration of regeneration, ecology of planarians in their natural habitats and their history as lab models. Part Two talks about experimental protocols for studying planarians, ranging from the establishment of a planarian research colony, to RNA and DNA extraction techniques, all the way to single stem cell transplantations or metabolomics analysis. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Planarian Regeneration: Methods and Protocols is a valuable resource for both newcomers to the field and experts within established planarian laboratories.

Book Description
Atlas of Early Zebrafish Brain Development: A Tool for Molecular Neurogenetics, Second Edition, remains the only neuroanatomical expression atlas of important genetic and immunohistochemical markers of this vertebrate model system. It represents a key reference and interpretation matrix for analyzing expression domains of genes involved in Zebrafish brain development and neurogenesis, and serves as a continuing milestone in this research area. This updated volume provides in-situ hybridized and immunostained preparations of complete series of brain sections, revealing markers of the fundamental stages in the life history of neuronal cells in very high quality preparations and photographic plates. Specific additions to this edition include documentation on the distribution of neurons expressing GABA, dopamine and serotonin, material on the basal ganglia, hypothalamus, and the caudal, segmented part of the diencephalon, new theories on the early organization of the telencephalon and thalamus, and integration of a comparative perspective on the mid- and hindbrain. - Documentation on the distribution of neurons expressing GABA, dopamine and serotonin - Material on the basal ganglia, hypothalamus, and the caudal, segmented part of the diencephalon - New theories about the early organization of the telencephalon and thalamus - Integration of a comparative perspective on the mid- and hindbrain

Book Description
This book provides cutting-edge studies and technologies using small fishes, including zebrafish, medaka, and other fishes as new model animals for molecular biology, developmental biology, and medicine. It also introduces eccentric fish models that are pioneering new frontiers of biology. Zebrafish and medaka have been developed as lower vertebrate model organisms because these small fish are easy to raise in the laboratory and are useful for the live imaging of the morphology and activity of cells and tissues in intact animals. By virtue of those specific advantages, fish studies have demonstrated the common features of vertebrates and raised further questions toward understanding the mystery of life. The book consists of four parts: “Development and Cell Biology”, “Homeostasis and Reproduction”, “Clinical Models”, and “Eccentric Fish”. Together they describes the core area of small fish study – often considered mere zoology but which is actually proving to be the universal basis of life. Written by leading scientists, the book helps readers to understand small fishes, inspires scientists to utilize small fishes in their studies, and encourages anyone who wants to participate in the large and fantastic world of small fish.
