Principles of Cloning is the first comprehensive book on animal cloning since the creation of Dolly. The contributing authors are the principal investigators on each of the animal species cloned to date and are expertly qualified to present the state-of-the-art information in their respective areas. Editors Cibelli, Lanza and West garnered worldwide spotlight late in 2001 when their company, Advanced Cell Technology, announced the successful engineering of the world's first cloned human embryo. The trio was featured in the US News & World Report December 2001 cover story, "The First Human Clone." The book presents the basic biological mechanisms of how cloning works and progresses to discuss current and potential applications in basic biology, agriculture, biotechnology, and medicine.
The topic of cloning, a lightning rod issue since the 1997 announcement of the cloned sheep Dolly, is one of the most exciting and promising areas of medical research if not the most controversial. While the moral debate over human cloning and the use of stem cells rages on, researchers are doggedly going about the business of developing cloning treatments for therapeutic uses in disease.Potential applications for cloning research include agricultural uses, medical treatments for diseases such as Parkinson's disease, and genetically modified foods. The research in this area has vast potential.
