...medicine any favors," said Dr. Marilyn Monk, a researcher at London's Institute of Child Health. Dr. Leeanda Wilton, director of embryology at Australia's Monash IVF Center, where much of the in-vitro fertilization technology was developed, said there were hundreds of scientists who could have split an embryo in half, just the way Hall and Stillman did. "They haven't done so because it opens a can of worms," she said...
...conceived a child, might you be interested in cloning the embryo...
Freed from the anchor of realism, fiction writers have drifted off in all sorts of strange directions. Huxley's idea was that cloning based on embryo splitting (he called it "bokanovskification") would be used to mass-produce drones for performing menial labor. Huxley's Gammas, Deltas and Epsilons were separated from the higher-class Alphas and Betas not just by economic status but also by biologically engineered physical and intellectual traits...
...dairy herds composed of carbon-copy cows, no pigpens filled with identical sows. While copying particular strains of valuable plants such as corn and canola has become an indispensable tool of modern agriculture, cloning farm animals, feasible as it may be, has never become widespread. Even simple embryo splitting, the technique used by the George Washington University researchers on human cells, is too expensive and complicated to take off commercially. "Cloning," says George Seidel, an animal physiologist at Colorado State University, "remains very much a niche technology...
...Wisconsin-based American Breeders Service, a subsidiary of W.R. Grace & Co., now owns the rights to cattle-cloning technology developed by Granada Biosciences, a once high-flying biotech firm that went out of business in 1992. The process calls for single cells to be separated from a growing calf embryo. Each cell is then injected into an unfertilized egg and implanted in the womb of a surrogate cow. Because the nucleus of the unfertilized egg is removed beforehand, it contains no genetic material that might interfere with the development of the embryo. In theory, then, it ought to be possible...
