    … "At that moment, I thought, 'This must be some kind of
    mistake'," Yamanaka said, according to an account of the
    discovery in Nature.

    But repeat experiments proved it to be anything but and the
    breakthrough would serve as a springboard for all kinds of
    medical research pursuits. Suddenly the thick, morality-lined
    clouds that hovered over embryonic stem cell research were
    parting to make way brighter, happier times. And stem cells
    harvested from adult cells rather than embryos would not only be
    a lot less controversial, but promise some practical benefits
    too, including lower risks of rejection by the immune system
    because they can be created from a patients own cells.
