The History of Cloning: Fact & Fiction
Kent E. Vrana, Ph.D., is a Professor and the Director of Graduate Studies in the Department of Physiology and Pharmacology at the Wake Forest University School of Medicine. Dr. Vrana supervises the Laboratory of Molecular Neurobiology and is Director of the Piedmont Triad Community Research Center Molecular Biology Core. Research efforts in his laboratory include: epigenetic imprinting by substance abuse and Neurotoxicology and the development of cloning technologies in non-human primates. He is funded by three ongoing grants from the National Institutes of Health and has published a textbook on biochemistry as well as more than 75 book chapters, journal articles and scientific reviews. He is a member of several federal review panels and editorial/advisory boards. He is also a member of the Center for Neurobiological Investigation of Drug Abuse (CNIDA), the Center for Neurobehavioral Study of Alcohol (CNSA), and the Addiction Studies Program for Journalists (all at the Wake Forest University School of Medicine).

Therapeutic vs. Reproductive Cloning

Reproductive Cloning in Animals
John Vandenbergh, Ph.D., is Chairman of the National Academy of Science (NAS) committee on "Defining Science-Based Concerns Associated with the Products of Animal Biotechnology." He is a Professor of Zoology at North Carolina State University (NCSU), where he began teaching and managing a research program in behavioral endocrinology in 1990. Dr. Vandenbergh previously served as Chairman of the Department of Zoology at NCSU, and has edited two books, written numerous chapters, and has published extensively on the behavior, genetics, and physiology of small mammals. He recently completed service on the National Research Council's "Council of the Institute for Laboratory Animal Research (ILAR)." His previous NAS committee service includes the committee on "Understanding the Biology of Sex and Gender Differences," the ILAR committees on the "Care and Use of Laboratory Animals," "Cost of and Payment for Animal Research," and the "Revised Guide for the Care and Use of Laboratory Animals."

Ethical and Social Considerations about Cloning
Larry Churchill, Ph.D., Co-Director, Center for Health Ethics and Policy;
Professor of Social Medicine, The University of North Carolina at Chapel
Hill School of Medicine. Churchill's teaching and research interests concern ethical issues in medical care, the ethical obligations of health professionals, and issues of justice in health policy. He is particularly interested in whether medicine can be said to have a distinctive ethic, and if so, what this means for doctors, for patients and for health policy in the United States. Current writing projects include revisions for an expanded paperback edition of Self-Interest and Universal Health Care (Cambridge: Harvard University Press, 1994) and a monograph on the ethics of health professionals in the managed care environment. Funded research projects include "Informed Consent to Gene Therapy" (National Center for Human Genome Research) with co-investigators Myra Collins, Nancy King and Keith Wailoo.
