Several factors helped the Koreans succeed where others had failed. To start with, they had a large supply of eggs. The researchers lined up 16 female volunteers who found the project through its website. To avoid any taint of coercion, the women weren't paid. They were fully informed about...
The scientists' basic strategy was the same as in most post-Dolly cloning experiments: remove the nucleus of the egg, with its single set of chromosomes, and replace it with the nucleus of a mature cell, containing two sets (in this case, the mature nuclei came from cumulus cells, which...
It could be years, however, before such replacement actually happens. "This is an important step forward," says Goldstein, "but it's just one obstacle out of the way." The Korean technique has only worked in women so far, perhaps because they alone have cumulus cells, which seem especially amenable to...
Even with sensible laws, of course, there's always a chance that cloning technology will be misused. Plenty of useful technologies are abused every day, says Dr. William Gibbons, professor of obstetrics and gynecology at Eastern Virginia Medical School--including automobiles and antibiotics. "It doesn't mean that these are...
