This book was released on 2013-06-29 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship of cell lineage and differentiation is one of the most intriguing problems in developmental biology. In most higher organisms, the analysis of the cell lineage has to rely on indirect methods. Only in the most suitable systems, like the nematodes, can the pattern of cell division be determined by direct observation under the microscope. In cases where this is not possible, the fate of the cells has to be examined by using cell markers. Most suitable for this purpose are genetic markers, provided that they do not interfere with the developmental pathway to be studied. However, suitable genetic markers and techniques for generating genetic mosaics are available in a few organisms only. Therefore, this volume is largely concerned with Drosophila and the mouse, which have been studied most extensively. In 1929 STURTEVANT introduced the analysis of gynandromorphs into devel opmental genetics. However, this important contribution remained largely unnoticed until the late sixties, when the potential of this technique for deter mining embryonic fate maps and the number of primordial cells was exploited, and the methodology extended to the mapping of mutational foci. Mitotic recombination was demostrated by STER:-

Download or read book Genetic Mosaicism written by János Szabad and published by Cambridge Scholars Publishing. This book was released on 2021-06-17 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of green and yellow ornamental plants around us, dark spots on our skin, people with brown and blue mosaic irises, and white-spotted dogs and horses are all well-known phenomena of life, and are recognisable genetic mosaics. Although such genetics mosaics live with us (and, in fact, we are all a genetic mosaics), little is known about the genetic bases of their origin. This book provides a general overview of the mechanisms that lead to the formation of different types of mosaics, listing an ample collection of examples to illustrate the impact of the genetic mosaics on our life. The book will appeal to the reader interested in understanding the relationship between genetic events and mosaicism, especially undergraduate and graduate students and medical doctors, as well as experts engaged in horticulture and animal breeding.

Download or read book The Hierarchical Genome and Differentiation Waves written by Richard Gordon and published by World Scientific. This book was released on 1999 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades numerous scientists have called for a unification of the fields of embryo development, genetics, and evolution. Each field has glaring holes in its ability to explain the fundamental phenomena of life. In this book, the author shows how the phenomenon of cell differentiation, considered in its temporal and spatial aspects during embryogenesis, provides a starting point for a unified theory of multicellular organisms (plants, fungi and animals), including their evolution and genetics. This unification is based on the recent discovery of differentiation waves by the author and his colleagues, described in the appendices, and illustrated by a flip movie prepared by a medical artist. To help the reader through the many fields covered, a glossary is included.This book will be of great value to the researcher and practicing doctors/scientists alike. The research students will receive an in-depth tutorial on the topics covered. The seasoned researcher will appreciate the applications and the gold mine of other possibilities for novel research topics.

Available in PDF, EPUB and Kindle. Book excerpt: Since the Russian edition of this book was published in 1975 many new research works have appeared which have made necessary some additions for the English edition, to reflect progress in molecular developmental genetics. Recent important findings in this field have brought about essential corrections to the concept of genetic regulation of the process of cell differentiation. The discovery of the mosaic structure of a gene prompted the re evaluation of our considerations about the regulation of gene activity in eukaryotes, and the data about transcriptional events during ontogenesis are of great importance as well. Formerly it was generally accepted that a derepression of genes was responsible for cell differentiation in the process of develop ment. Recently three important conclusions have been derived (Davidson and Britten, 1979) which help to pose the problem in a new way: 1) Only a small part of single copy sequences of DNA is represented in nuclear RNA of a given type of cell or tissue: 10% to 20% in sea urchin embryos, 11 % in rat liver, 4% to 6% in Drosophila cell culture, etc. Since only about 10% of single copy sequences represent the structural genes (Davidson and Britten, 1973), transcription of almost the whole set of structural genes occurs.
Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
Download or read book Mosaicism in Human Skin written by Rudolf Happle and published by Springer Science & Business Media. This book was released on 2013-11-26 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mosaicism is a powerful biologic concept, originally developed from studying plants and animals. All cutaneous neoplasms, both benign and malignant, reflect mosaicism, which is the necessary basis to explain numerous human skin disorders. For example, various mosaic patterns visualize the embryonic development of human skin and X-linked skin disorders explain why women live longer than men, and so on. This book presents, for the first time, a comprehensive overview on the strikingly manifold patterns and peculiarities of mosaic skin disorders. This reader-friendly structured and straightforward publication will help the dermatologist to understand the underlying molecular mechanisms of skin disorders in order to further improve the treatment outcome.
Download or read book Embryogenesis Explained written by Natalie K Gordon and published by World Scientific. This book was released on 2016-09-15 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: The greatest mystery of life is how a single fertilized egg develops into a fully functioning, sometimes conscious multicellular organism. Embryogenesis Explained offers a new theory of how embryos build themselves, and combines simple physics with the most recent biochemical and genetic breakthroughs, based on the authors' prediction and then discovery of differentiation waves. They explain their ideas in a form accessible to the lay person and a broad spectrum of scientists and engineers. The diverse subjects of development, genetics and evolution, and their physics, are brought together to explain this major, previously unanswered scientific question of our time.As a follow up on The Hierarchical Genome, this book is a shorter but conceptually expanded work for the reader who is interested in science. It is useful as a starting point for the curious layman or the scientist or professional encountering the problem of embryogenesis without the formal biology background. There is also material useful for the seasoned biologist caught up in the new rush of information about the role of mechanics in developmental biology and cellular level mechanics in medicine.

Download or read book Stem Cells and the Future of Regenerative Medicine written by Institute of Medicine and published by National Academies Press. This book was released on 2002-01-25 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush's watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.
