...today's political climate, research like this is a hot-button issue. The use of federal funds for research on human embryos is already prohibited, although that ban does not extend to work done in privately funded research labs. That's why private in vitro-fertilization clinics flourished in the 1980s with almost no federal regulation. What some commission members feared was that the same thing could happen with research on human cloning...
...really the first time? Is cloning all that different from genetically engineering an embryo to eliminate a genetic disease like cystic fibrosis? Is it so far removed from in vitro fertilization? In both those cases, after all, an undeniable reductiveness is going on, a shriveling of the complexity of the human body to the certainty of a single cell in a Petri dish. If we accept this kind of tinkering, can't we accept cloning? Harvard neurobiologist Lisa Geller admits that intellectually, she doesn't see a difference between in vitro technology and cloning. "But," she adds, "I admit...
Whether they will or not is impossible to say. Even if governments ban human cloning outright, it will not be so easy to police what goes on in private laboratories that don't receive public money--or in pirate ones offshore. Years ago, Scottish scientists studying in vitro fertilization were subjected to such intense criticism that they took their work underground, continuing it in seclusion until they had the technology perfected. Presumably, human-cloning researchers could also do their work on the sly, emerging only when they succeed...
...requiring fewer monkeys. "The downside," Wolf said, "is that this is one step in the direction of suggesting that nuclear transfer can be done in human beings," He insisted that the center has no interest in cloning a person. The twins, born in August to surrogate mothers through in vitro fertilization, can expect to live normal monkey lives of 15 to 20 years, researchers said. But huddled in the corner of their cage, hugging each other, they looked a lot like two frightened children. They're not the only ones who are worried...
...president of the Jones Institute for Reproductive Medicine at the Eastern Virginia Medical School. The Institute had developed a procedure that could enable her and David to have a healthy child, and Hodgen wanted them to try it. The procedure, called preimplantation genetic diagnosis, is a marriage of in vitro fertilization and high-tech genetic testing. PGD begins with a standard in vitro fertilization, but then, when the embryos have divided to between four and eight cells, technicians remove one or two cells and test them for the harmful gene carried by the parents. The embryos develop normally even though...
