| An ethics crisis at one of the world’s
most successful human embryonic stem cell laboratories has plunged the
controversial field of research into a new swirl of uncertainty. The accusations
surrounding Korean cloning expert Woo Suk Hwang of Seoul National
University--the first scientist to grow stem cells inside cloned human
embryos--has already killed a spate of planned studies that sought to prove the
cells’ medical potential. The claims that Hwang may have obtained human eggs for
his studies from women who felt pressured to donate are also reigniting a
long-smoldering debate in the United States over the ethics of paying young
women for their eggs, which are difficult to obtain but essential to the
production of stem cells tailored to individuals. Egg donation, which is generally safe but occasionally leads to serious and A. Hwang paid the women for their eggs in his studies. B.
