...Though Dolly the sheep was the first clone to be shoved into the limelight, in 1996, the process of human-directed cloning has existed since 1952. In that year, American researchers Robert Briggs and Thomas King successfully removed the nucleus of a tadpole's embryonic cell and transferred it to a donor cell, cloning 27 tadpoles in the experiment. This groundbreaking achievement landed the scientists the internationally lauded Charles Leopold Mayer Prize of the Académie des Sciences, making them the first Americans in history to receive the award. (Read TIME's first story about Dolly...
...Since Briggs and King's discovery, a veritable Noah's Ark of clones has been created, ranging from fish in 1963 to horses in 2003. Dolly's birth, at the Roslin Institute in Scotland, marked the first successful cloning of a mammal from an adult cell, proving that a complete animal could be grown from the DNA contained in cells from just about any part of another...
...Cloning has generated controversy outside of ethics questions as well - or at least, outside of these particular ethics questions. In 2004, South Korean researcher Hwang Woo Suk shot to fame after claims that his team had successfully extracted potentially disease-curing stem cells from a cloned human embryo. However, mere months later, Hwang's reputation dissolved after a Seoul National University panel concluded that much of his research was "intentionally fabricated." Hwang was accused of doctoring pictures of his supposed patient-specific stem-cell lines and was forced to resign. Though the controversy stunned South Korea, the nation resumed...
...Stem cell research usually makes news when scientists use it to grow something. Take, for example, this week’s story about the successful transplantation of a windpipe grown from stem cells. But while transplantation is “a very exciting application of stem cells,” it is not a solution for many diseases, as stem cell and regenerative biology professor Kevin Eggan said in a talk last night, titled “Using Stem Cells and Reprogramming to Model Neural Degeneration.” For example, he said it is difficult to imagine growing...
...pharmaceutical giant Pfizer is planning to create a regenerative medicine unit specializing in stem cell research in Cambridge, according to a company press release. The unit will further Cambridge’s ongoing effort to maintain its status as a world-class hub of scientific research while stimulating the local economy and offering economic opportunities during the current financial crisis, proponents say. “It seems like a natural progression that will add to the breadth and scope of biotech here in Cambridge,” Mayor E. Denise Simmons said of the project. Simmons said the labs will...
