Cell Lineage Specification And Patterning Of The Embryo

International Review of Cytology presents current advances and comprehensive reviews in cell biology, both plant and animal. Articles address structure and control of gene expression, nucleocytoplasmic interactions, control of cell development and differentiation, and cell transformation and growth. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research. This volume brings together current information on the localization and roles of RNAs in cell-lineage determination and subsequent patterning in embryonic development. Guest co-editor Lawrence Etkin is one of the leading researchers in molecular genetics of Xenopus. Key Features * A number of important concepts are discussed, including: * How polarity is established during oogenesis * How germ cell determinants become organized in the establishment of the germ cell lineage * Different strategies used by organisms to establish the germ cell lineage * Similarities and differences between the mechanisms used in embryonic patterning * The mechanisms and machinery by which molecules such as RNA become asymmetrically segregated * The use of similar signaling pathways in patterning of the dorsal-ventral and right-left asymmetries, embryonic germ layers, limb, and nervous system * The link between fundamental biological processes such as RNA translation and localization in the regulation of axis specification

Five leaders in the field of mammalian preimplantation embryo development provide their own perspectives on key molecular and cellular processes that mediate lineage formation during the first week of life. The first cell-fate decision involves the formation of the pluripotent inner cell mass (ICM) and extraembryonic trophectoderm (TE). The second cell-fate choice encompasses the transformation of ICM into extraembryonic primitive endoderm (PE) and pluripotent epiblast. The processes, which occur during the period of preimplantation development, serve as the foundation for subsequent developmental events such as implantation, placentation, and gastrulation. The mechanisms that regulate them are complex and involve many different factors operating spatially and temporally over several days to modulate embryonic chromatin structure, impose cellular polarity, and direct distinct gene expression programs in the first cell lineages.

The last ten years have shown a dramatic revolution in our understanding of early animal development. This new edition of the successful first edition describes the result of this revolution and explains how the body plan of an embryo emerges from the newly fertilised egg. The book starts with a critical discussion of embryological concepts and explains in simple terms the mathematics of cell states, morphogen gradients and threshold responses. The experimental evidence on the mechanism of regional specification in Xenopus, molluscs, annelids, ascidians as well as Caenorhabditis, the mouse, the chick and Drosophila is then discussed. The whole chapter devoted to the exciting developments in Drosophila provides a clear guide to the subject, including a new table outlining the developmentally important genes. The emphasis throughout is on conceptual clarity and unity: bringing together the mathematical models, embryological experiments and molecular biology into a single, comprehensive coherent account.

Defines the current status of research in the genetics, anatomy, and development of the nematode C. elegans, providing a detailed molecular explanation of how development is regulated and how the nervous system specifies varied aspects of behavior. Contains sections on the genome, development, neural networks and behavior, and life history and evolution. Appendices offer genetic nomenclature, a list of laboratory strain and allele designations, skeleton genetic maps, a list of characterized genes, a table of neurotransmitter assignments for specific neurons, and information on codon usage. Includes bandw photos. For researchers in worm studies, as well as the wider community of researchers in cell and molecular biology. Annotation copyrighted by Book News, Inc., Portland, OR
