Man’s embryo successfully cloned in US This might be a little too much offtopic piece of news but it’s such an achievement I’m sure most of you will find it interesting anyway: US scientists say they have produced embryos that are clones of two men, in an attempt to produce patient-specific stem cells. Researchers removed DNA from donated human eggs, and replaced it with DNA from the skin cells of two volunteers. They produced embryos with genetic material that matched the men’s, but did not go on to extract stem cells. The team at Stemagen Corporation in La Jolla, California, says the work could be an important step to developing embryonic stem cells for patients. They produced five embryos called blastocysts from 25 donated eggs. DNA fingerprinting proved that at least one of these was a clone.
