Wilmut said positive aspects of cloning could include creating pigs with organs more acceptable to human bodies for transplants and using sheep to study cystic fibrosis...
VEINS AND ARTERIES. Blood vessels present a special challenge: they must be strong yet flexible enough to expand and contract with each heartbeat. Joseph Vacanti's group has grown a tube of sheep-muscle cells around a polymer, added closely packed lining cells to the inside and stitched it into a sheep's pulmonary-artery circuit. Blood pulsing against the walls gradually strengthens the muscle cells, just as weight training builds biceps. To make smaller vessels, Laval's Auger bends a sheet of muscle cells around a plastic tube and reinforces it with an outer layer of stiffer cells. Then...
Harvard's place names attest to this once bucolic setting: the Yard used to actually be a "yard," Cambridge Common a shared pasture where sheep and cattle were grazed. As Harvard matured, red brick replaced the briars, and asphalt smothered up the asphodels. But in spite of the modernization, a modest ecosystem still survives.
