Seed has begun to remind pundits and editorial writers of Dr. Jack Kevorkian, who provokes strong feelings by shattering the taboo against physician-assisted suicide. The technical challenge involved in ending a human life is trivial, however. Cloning is another matter. Ian Wilmut, the embryologist who produced Dolly, the first clone of an adult mammal, says there are "serious safety issues" involved in cloning a human. In his experiments with animals, a quarter of his lambs died within a few days of birth. Ultimately, it took 277 attempts to produce Dolly. "Should we really consider or allow experiments of this...
Dolly is a carbon copy of her mother, grown from a cell taken from an adult ewe's mammary gland. The father, in a sense, is embryologist Ian Wilmut, who as a boy wanted to be a farmer but, after a summer of laboratory work, became enchanted by the magical progression of embryos from amorphous balls of cells into living entities of exquisite complexity. In the pursuit of the advancement of animal husbandry (and, by extension, human nutrition and health), he began experimenting with cloning at Scotland's Roslin Institute. His vision was the creation of genetically engineered farm animals...
This year's list of nominees was typically eclectic. Should we honor the Scottish embryologist Ian Wilmut and his immortal cloned sheep Dolly? What about Tiger Woods' thrilling 350-yd. drives into history? Or Alan Greenspan's steady-on-the-tiller stewardship of America's ongoing economic boom? Or--of course--the life and death of Diana, Princess of Wales...
...Best-Known Clone Embryologist Ian Wilmut made a big splash in the gene pool when he announced that he had cloned a sheep named Dolly. Though animals had been duplicated before, Dolly was the first ever created from an adult cell rather than an embryonic one, raising the specter that a human will one day follow in her hoofsteps...
Australian embryologist David Gardner and his colleagues at the Colorado Center for Reproductive Medicine in Englewood have come up with a mixture that keeps cells growing in vitro for up to five days, making it much easier to pick out the strongest embryos. So instead of three or four or five embryos, doctors can implant one or two. The technique could be a standard practice by next spring...
