Cloning Human Embryos

"Scientists at Harvard and Children's Hospital Boston announced Tuesday they have the green light to clone human embryos that could generate stem cell lines for specific diseases. The researchers join a small cadre of scientists worldwide attempting to do what a South Korean scientist claimed to have done, only to have his work unravel when it was exposed as a fraud. "We are convinced that work with embryonic stem cells holds enormous promise," Harvard's Steven Hyman said. Embryonic stem cells are the precursor cells to almost every tissue in the body; growing them could provide replacement tissues for diseases such as diabetes and cancer. In theory, the body would not reject the tissues from cloned embryos. Cloning requires inserting a cell from a patient into an egg and chemically triggering division of their union. So far, only a team at the U.K.'s University of Newcastle Upon Tyne apparently has created a cloned human embryo." By Dan Vergano. USA Today, Yahoo News Link to Article (last visited 6-7-06 NVS)
