Cloning has the potential to be an extremely valuable tool across many fields. In agriculture, the reproductive cloning of farm animals could prove to be advantageous. In clinical medicine, the employment of therapeutic cloning for cell, tissue, and organ replacement appears to be imminent. In Epigenetic Risks of Cloning, 32 leading researchers detail the cloning methods being employed with various animal models, providing both a review of current findings and a discussion of potential concerns. Less than four percent of reconstructed embryos typically develop to adulthood, the cumulative result of inefficiencies occurring at every stage of development. This book considers the very real consequences of those inefficiencies: high rates of fetal, perinatal, and neonatal loss, as well as the production of abnormal offspring. At present, there is a legitimate concern that the propensity for epigenetic errors could be paralleled in human embryos.

Mammalian and Avian Transgenesis presents a collection of novel methods for the production of a wide range of transgenic animals. The manual focuses largely on mice, but also contains protocols for successful transgenesis in rats, cows, pigs and birds. The manual provides detailed, step-by-step protocols covering all aspects of the production of transgenic animals, including the use of lentiviral vectors in gene transfer, intracytoplasmic sperm injection, nuclear transfer, large insert transgenesis, conditional gene expression systems, the use of reporter genes in transgenesis and transgenesis in large animals and birds. The text is supplemented by superb color photos. While the focus is on newly established techniques, the fundamental methods of transgenesis are also covered for those new to the field. Thus this manual is perfectly suited for those wishing to adopt new technologies in transgenesis.

Human reproductive cloning is an assisted reproductive technology that would be carried out with the goal of creating a newborn genetically identical to another human being. It is currently the subject of much debate around the world, involving a variety of ethical, religious, societal, scientific, and medical issues. Scientific and Medical Aspects of Human Reproductive Cloning considers the scientific and medical sides of this issue, plus ethical issues that pertain to human-subjects research. Based on experience with reproductive cloning in animals, the report concludes that human reproductive cloning would be dangerous for the woman, fetus, and newborn, and is likely to fail. The study panel did not address the issue of whether human reproductive cloning, even if it were found to be medically safe, would be—or would not be—acceptable to individuals or society.
