The Next Step in Therapeutic Cloning
As reported by Wired (and in numerous other places), Korean researchers have accomplished the next successful step in therapeutic cloning and stem cell medicine: reliably extracting stem cells from cloned human embryos. As the Wired article says, "a Korean woman now has a set of cells that could one day replace any damaged or diseased cell in her body with little worry of rejection, if researchers can get stem cells to work therapeutically." The scientists have even managed to create a new stem cell line from this work, which is very good news, given the limited number of lines currently available. A New York Times article provides a good introduction to the medical significance of this advance.
