Monkey Embryonic Stem Cell Breakthrough -- Finally
Ronald Bailey | June 21, 2007, 4:18pm
"It may never to possible to clone humans because of a quirk in our
biology," reported a number of publications back in April 2003. The claim
was based on the fact that stem cell researchers were having no luck at all
in cloning primates such as rhesus monkeys. At the end of December 2004,
University of Pittsburgh researchers associated with now disgraced South
Korean stem cell faker, Woo-Suk Hwang, announced that they had coaxed cloned
rhesus monkey eggs to the blastocyst stage. Earlier this year, it was
revealed that that data had been faked too.
But today Reuters is reporting success at last in creating embryonic stem
cell lines from monkeys. To wit:
Human therapeutic cloning has moved a step closer after U.S. researchers
said they had successfully created embyonic stem cells from monkey embryos.
In what would be a world-first breakthrough, scientists told a stem cell
research conference in the Australian city of Cairns this week that they had
successfully created two batches of embryonic stem cells from cloned rhesus
monkey embryos...
Shoukhrat Mitalipov of the Oregon National Primate Research Centre in the
United States said he had succeeded using modified Somatic Cell Nuclear
Transfer, or SCNT, in which an egg cell nucleus is removed and replaced with
a donor nucleus.
The cell eventually forms an early embryo, or blastocyst, with DNA almost
identical to the donor organism.
Mitalipov said he used skin cells from a 10-year-old male rhesus monkey and
presented the conference with proof of his success using DNA evidence. He
also showed slides of the embryonic cells changing into heart cells and
neurons.
"Never" in this case lasted a little over four years. As Nobelist and nano
researcher, Richard Smalley once said:
"When a scientist says something is possible, they're probably
underestimating how long it will take. But if they say it's impossible,
they're probably wrong."
Of course, this research needs to be replicated. Whole Reuters article here.
