Shortly after the Dolly announcement was made, scientists
in Oregon announced that they had used a related technique to clone monkey
embryos. In this simpler two-step process, a monkey embryo was first created
with the standard technique of stirring monkey eggs and sperm together.
Once the embryo divided into eight cells, the cells were carefully separated,
and DNA from each cell was inserted into fresh egg cells whose DNA had been
removed. These cells then grew into embryos that were implanted into female
Unlike the process that created Dolly, the Oregon technique
is not technically considered cloning, since the cells used were from embryos
and not from an adult. However, this research does bring the cloning question
a little closer to home, adding to a growing body of evidence that suggests
that human cloning is possible--maybe even close at hand.
