A Start on Research Cloning
Hats off to Harvard and the University of California at San Francisco for undertaking stem cell research that the Bush administration is trying to discourage and political leaders in Washington seem unwilling to support. Both institutions have started programs to clone human embryos and extract stem cells from them, thus creating stem cell lines tailor-made to study specific diseases. Their bold moves, made after intense soul-searching over the ethical and scientific issues, should help to revive a promising field of research ââ?¬â? known as therapeutic or research cloning ââ?¬â? that had been staggered by a scandal in South Korea.
