Book Description
A long time ago botany used to be regarded as the scientia amabilis, the friendly science, eminently suitable for leisured amateurs. Since then, and particularly in this century, it has grown tremendously in its importance and in its intimate contacts with various other disciplines of science, some of which, like plant genetics and plant physiology, at one time indeed used to be included under the broad term botany. In spite of the fact that such subjects have expanded into major scientific fields of their own, botany, the mother science, continues to maintain its central place: this is because it deals with plants which constitute one of the most vital life-supporting systems of this planet. Furthermore, interacting and benefiting from advances made in other sciences, it has steadily progressed in a number of areas. Experimental embryology of vascular plants is one such field where spectacular advances have been made in recent years. The time is therefore particularly opportune for the publication of an authoritative book on the subject. It is very appropriate that the book has been planned and edited by Professor B. M. Johri, one of India's foremost botanists, whose contributions in embryology, plant morphology and morphogenesis are internationally known. He was closely associated over a number of years with Professor P. Maheshwari, the great botanist and embryologist, to whom the book is dedicated.

Book Description
Embryology and Phylogeny in Annelids and Arthropods describes the embryology of segmented invertebrates, utilizing morphological facts of embryonic development in the furtherance of speculations on phylogenetic relationships. This book begins with an introduction to embryology and phylogeny, followed by a discussion on the experimental embryology of animals groups, such as polychaetes, oligochaetes and leeches, onychophorans, myriapods, apterygote and pterygote insects, crustaceans, and chelicerates. The cleavage, gastrulation, and basic pattern of development of these invertebrates are also provided. This text concludes with a presentation of the onychophoran-myriapod-hexapod assemblage or Uniramia. This publication is recommended for experimental embryologists researching on the embryonic development in annelids and arthropods.

Book Description
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.

Book Description
Here is a critical account of the experimental work of German biologist and Nobel laureate Hans Spemann, one of the founders of experimental embryology. The author, a distinguished developmental biologist, spent almost a decade in Spemann's laboratory. He examines Spemann's work and traces the different lines of investigation which emerged from his mentor's seminal research, and laid the foundation for modern cellular and developmental biology.

Book Description
Most people have some interest in embryos; this probably results, in part, from their interest in understanding the biological origins of themselves and their offspring and, increasingly, concerns about how environmental change such as pollution might affect human development. Obviously, et- cal considerations preclude experimental studies of human embryos and, c- sequently, the developmental biologist has turned to other species to examine this process. Fortunately, the most significant conclusion to be drawn from the experimental embryology of the last two decades is the manner in which orthologous or closely related molecules are deployed to mediate similar - velopmental processes in both vertebrates and invertebrates. The molecular mechanisms regulating processes fundamental to most animals, such as axial patterning or axon guidance, are frequently conserved during evolution. (It is now widely believed that the differences between phyla and classes are the result of new genes, arising mostly by duplication and divergence of extant sequences, regulating the appearance of derived characters. ) Other vertebrates are obviously most likely to use the same devel- mental mechanisms as humans and, within the vertebrate subphylum, the - parent degree of conservation of developmental mechanism is considerable. It has long been recognized that particular vertebrate species offer either d- tinct advantages in investigating particular stages of development or are - pecially amenable to particular manipulations. No single animal can provide all the answers because not all types of experiments can be carried out on a single species.
