During the past 20 years, transgenesis has become a popular technique and a crucial tool for molecular geneticists and biologists. Transgene expression is now better-controlled and even specifically inducible by exogenous factors. While these techniques have quite significantly transformed the experimental approaches taken by biologists, the applications are more limited than expected and concerns have arisen regarding biosafety as well as physiological, social, and philosophical issues. Transgenic Animals: Generation and Use contains articles on the techniques used to generate transgenic animals and a section on the preparation of vectors for the optimally controlled expression of transgenes. It also examines the use of transgenic animals in the study of gene function and human diseases, the preparation of recombinant proteins and organs for pharmaceutical and medical use, and the improvement of genetic characteristics of farm animals. Finally, it discusses more recent problems generated by transgenic animals including conservation of transgenic lines, specific database patenting, biosafety, and bioethics. Drawn from both academia and industry, the contributors to this monograph present in one concise volume all the relevant information on the different aspects of transgenesis. This book can be used as both a reference book and a textbook for specialized university courses and will be of interest to everyone involved in basic research in animal biology, molecular genetics, animal biotechnology, pharmaceutical science, and medicine.

Genetic-based animal biotechnology has produced new food and pharmaceutical products and promises many more advances to benefit humankind. These exciting prospects are accompanied by considerable unease, however, about matters such as safety and ethics. This book identifies science-based and policy-related concerns about animal biotechnologyâ€"key issues that must be resolved before the new breakthroughs can reach their potential. The book includes a short history of the field and provides understandable definitions of terms like cloning. Looking at technologies on the near horizon, the authors discuss what we know and what we fear about their effectsâ€"the inadvertent release of dangerous microorganisms, the safety of products derived from biotechnology, the impact of genetically engineered animals on their environment. In addition to these concerns, the book explores animal welfare concerns, and our societal and institutional capacity to manage and regulate the technology and its products. This accessible volume will be important to everyone interested in the implications of the use of animal biotechnology.
A transgenic animal is one that is genetically modified to carry genes from another species. Transgenic species can be raised to carry potentially useful genes from a variety of species. While the topics of genetic engineering and cloning are controversial, the reality is that these technologies offer tremendous benefits to society - from offering a framework for developing and screening medical therapies, to enhancing the safety and nutrition of the food we eat. One potential application of research into transgenic animal technology is the creation of domestic animals genetically designed to express a certain human disease and therefore serve as models for the study and treatment of human illnesses. Although many mouse models of human diseases are available today, such models in large domestic animals physiologically more similar to humans are sparse and critically needed. Further research in this field will undoubtedly uncover many more direct and indirect benefits of this technology.

In the past decade, a number of advances have been made in genetic engineering as applied to farmed animals. This book has been developed from invited presentations at a conference held in California in August 1997, to address this issue. It is written by representatives from the leading laboratories involved in attempts to improve agriculturally important mammals, poultry and fish. Current knowledge, methodology, technical improvements and successes in the applications of transgenic technology to a range of animals which are important in agriculture are brought together for the first time under one cover. This book is essential reading for research workers in animal genetics, breeding and biotechnology.
Arranging the transportation of animals at research facilities is often an ordeal. There is a confusing patchwork of local, national, and international regulations; a perceived lack of high-quality shipping services; a dearth of science-based good practices; and a lack of biosafety standards. It's a challenge â€"and an impediment to biomedical research. Guidelines for the Humane Transportation of Research Animals identifies the current problems encountered in the transportation of research animals and offers recommendations aimed at local and federal officials to rectify these problems. This book also includes a set of good practices based on the extensive body of literature on transportation of agricultural animals, universal concepts of physiology, and a scientific understanding of species-specific needs and differences. Good practices were developed by the committee to address thermal environment, space requirements, food and water requirements, social interaction, monitoring of transportation, emergency procedures, personnel training, and biosecurity. Guidelines for the Humane Transportation of Research Animals is an essential guide for all researchers, animal care technicians, facilities managers, administrators, and animal care and use committees at research institutions.
Some of the current concepts used in transgenic research, an increasingly important tool to study the regulation and function of genes, are illustrated in this book. With these techniques, animal models can be used to study human diseases; this opens up new possibilities in both applied and basic research. Specifically, the ability to introduce genes into the germline of mice and the successful expression of the inserted gene within an organism provide new insights and opportunities for biomedical research. The discussion here shows how a detailed analysis of the underlying molecular mechanisms will provide new insights into the genetic origin of certain diseases and will lead to a better understanding of normal and abnormal physiological processes.
v Preface The quality of animal models used in biomedical research has increased substantially since the first successful microinjection of foreign DNA frag ments into a mouse zygote in the early 1980s. New well-defined animal models, developed either by micro injection techniques or by homologous recombination in embryonic stem (ES) cells, have become widely available and several classical animal models have now been replaced by these transgenic models. Transgenic animals also fulfill increasingly important roles in other fields, like livestock production or in biopharming. The potential benefits of this technology are overwhelming. It is not surprising that many research groups have rushed to jump on this wagon of scientific progress. However, no matter how important these developments are, they can not relieve us of the moral obligations towards the animals. It is generally recognized that animal use is allowed only if the harmful effects are out weighed by the potential benefits of the experimental results. But what are the harmful effects? What is the impact of trans genesis on the well-being of animals? In order to gain more insight into this aspect of trans genesis the European Commission (DGXII) has funded a 12-month project with the aim of col lecting information on the production and use of transgenic animals in EU Member States and, more specifically, to obtain information as to what extent specific welfare problems may arise and whether or not studies are being performed on the incidence of welfare problems.
