BEIJING, Aug. 12 (Xinhuanet) -- British scientists say they have received
permission to clone human embryos for medical research. Such
license is believed to be the first to be granted in Europe.
In a procedure based on the same technique that created Dolly, the first
cloned sheep, the scientists will create embryos as a source of stem cells to
help develop new treatments for diabetes and degenerative diseases such as
Alzheimer's and Parkinson's.
They will duplicate early-stage embryos and extract stem cells from them.
The embryos will be destroyed before they are 14 days old and will never be
allowed to develop beyond a cluster of cells the size of a pinhead.
Earlier this year, scientists in South Korea announced that they had
produced the first human cloned embryos.
