Researchers at McGill say they have achieved a Canadian first by successfully producing three litters of cloned pigs, an event that may help advance research into human ailments such as diabetes. "It gives us the opportunity to create animals from cell lines that can be easily manipulated in vitro," said Dr. Vilceu Bordignon, director of the Large Animal Research Unit at McGill's Macdonald campus. "It could even lead to the development of new cell therapies for genetic diseases in humans."
