1.   Even the National Institutes of Health, which had never paid much attention to cloning, is expecting to support researchers who would try to clone early monkey embryos.

2.   If scientists can add genes to monkey embryos, it should be possible to add genes to human embryos, raising the emotionally fraught issue of human genetic engineering.

3.   If it got into the monkey embryos and functioned, the embryo cells would glow green under a fluorescent light.

4.   Scientists in Oregon have divided an eight-cell monkey embryo into quarters, creating identical quadruplet embryos.
