...possible to create a patient’s “own” tissue by a method known as nuclear transfer. The idea is to transfer the nucleus of one of the patient’s body cells to an egg cell from which the nucleus was removed, resulting in a so-called nuclear transfer embryo. Stem cells obtained from such an embryo are genetically identical to that of the patient. Regenerative tissue derived from these stem cells escapes immune rejection...
President Bush intends to ban nuclear transfer. If realized in a clinical phase, nuclear transfer will require a patient to donate one of his or her own body cells. Clinicians then mix this body cell in a test tube with an egg cell, and produce life-saving tissue. Patients receive transplantation without being dangerously immune-suppressed. When considered in its actual context, nuclear transfer is a simple and highly innovative medical technique. It is a technical process with no intention of creating a human being...
...Numerous animal studies indicate, however, that it is unlikely to work in the sense of producing normal individuals. Aside from the scientific limitations, responsible policy choices can eliminate the possibility of reproductive cloning in practice. Given simple and strict legislation and oversight, the line between reproductive cloning and nuclear transfer is clear and enforceable. Just because someone might abuse a technology to do harm against all odds and in defiance of the law surely should not mean we should ban the technology all together...
Several countries, including the United Kingdom and Singapore, endorse nuclear transfer research, but strictly prohibit any attempts at reproductive cloning. This means that a ban on nuclear transfer in the United States may lead to a brain drain outside of U.S. academic and corporate laboratories. Nor is it inconceivable that new medical treatments become available abroad while the United States is under...
Specialists in the U.S. often transfer several embryos into the womb during in vitro fertilization (IVF) in hopes of boosting the chance that one of them will "take" and therefore boost their clinic's success rate. Studies suggest, however, that the odds of a successful pregnancy may be the same whether you implant one, two or three embryos. Many European countries have decided to restrict their IVF clinics to one or two embryos per pregnancy. Dr. Lockwood and other physicians think such a limit might make sense in the U.S. as well...
