Book Description
Examines the establishment of the germ layers and other cell lineages in the early embryo including details of cell movements during the beginning stages of primitive streak formation. Discusses patterns of gene expression during the development of such tissues as the limb bud, skeletal, muscle and the central nervous systems placing special emphasis on commitment to particular cell types. Although it concentrates on the mouse as an example of mammalian development--chick, amphibian and Drosophila embryogenesis are employed whenever these organisms are more applicable to the study of a particular problem.

Book Description
The study of birth defects has assumed an importance even greater now than in the past because mortality rates attributed to congenital anomalies have declined far less than those for other causes of death, such as infectious and nutritional diseases. It is estimated that as many as 50% of all pregnancies terminate as miscarriages. In the majority of cases this is the result of faulty development. Major congenital malformations are found in at least 2% of all liveborn infants, and 22% of all stillbirths and infant deaths are associated with severe congenital anomalies. Teratological studies of an experimental nature are neither ethical nor justifiable in humans. Numerous investigations have been carried out in laboratory animals and other experimental models in order to improve our understanding of abnormal intrauterine development. In less than two decades the field of experimental teratology has advanced phenomenally. As a result of the wide range of information that is now accumulating, it has become possible to obtain an insight into the causes, mechanisms, and prevention of birth defects. However, considerable work will be needed before these problems can be resolved. The comributions in this volume include some of the more recent and exciting observations on the cellular and molecular aspects of developmental defects. It is not only a documentation of the latest experimental work, but it also indicates new and important areas for future research.

Book Description
What was it like to be a woman scientist battling the “old boy’s” network during the 1960s and 1970s? Neena Schwartz, a prominent neuroendocrinologist at Northwestern University, tells all. She became a successful scientist and administrator at a time when few women entered science and fewer succeeded in establishing independent laboratories. She describes her personal career struggles, and those of others in academia, as well as the events which lead to the formation of the Association of Women in Science, and Women in Endocrinology, two national organizations, which have been successful in increasing the numbers of women scientists and their influence in their fields.The book intersperses this socio-political story with an account of Schwartz’s personal life as a lesbian and a description of her research on the role of hormones in regulating reproductive cycles. In a chapter titled “Don’t Ask, Don’t Tell,” she examines the “evidence” from a scientist’s point of view for the hormonal and genetic theories for homosexuality. Other chapters provide advice on mentoring young scientists and a discourse on why it matters to all of us to have more women doing and teaching science. She also describes the process of putting together an interdisciplinary Center on Reproductive Science at Northwestern, which brought together basic and clinical scientists in an internationally recognized program of research and practice.

Book Description
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
