Editor's note. I trust you had
a wonderful Christmas. The following article, written by Wesley Smith,
is another example of his keen insight on a myriad of issues.
************** Another Cloning "Breakthrough": The world's first phony stem cells By Wesley J. Smith In February 2004, Woo--Suk Hwang made world headlines when he claimed to have cloned human embryos using a technique called somatic cell nuclear transfer, and then to have derived a line of stem cells from the embryos that could be used for medical research. Enthusiasm for this first "successful" experiment in human cloning, published in the prestigious peer--reviewed journal Science, was tempered by the inefficiency of the process: It took 242 human eggs to get just one embryonic stem cell line.
That problem seemed solved when, last
May, Hwang published another article in Science asserting that he had
again successfully cloned human embryos, this time deriving 11 stem cell
lines and, moreover, reporting an astounding 10--fold increase in
egg--use efficiency. Cloning proponents were giddy, declaring that the
age of therapeutic cloning was nigh. Soon, they predicted, sick patients
would be able to clone embryos made of their own tissue, from which, in
turn, genetically matched stem cells could be derived for use in
regenerative medical treatments.
Hwang's paper was greeted joyously by
cloning advocates and their media allies in the United States for
another reason: The research had been done in South Korea. Hwang's
"breakthrough" therefore proved that the United States was "falling
behind" in stem cell research. Hence, they argued, President Bush's
policy limiting federal funding of embryonic stem cell research to lines
created before August 9, 2001, must be overturned to permit American
research to flourish.
Meanwhile, Hwang was lauded
internationally as a genius and embraced by his countrymen as a national
hero. The South Korean government created a postage stamp in his honor,
depicting a figure leaping out of a wheelchair. (Never mind that such
therapeutic benefits remained hypothetical; never mind that an unjustly
neglected South Korean colleague had already restored partial mobility
and feeling to a paralyzed woman using umbilical cord blood stem cells
that require no cloning and no sacrificed embryos.) Hwang looked like a
Nobel laureate in waiting.
Then the roof caved in. In
mid--November, Hwang's American research partner, Gerald Schatten of the
University of Pittsburgh, severed ties with him, complaining that the
South Korean had purchased the human eggs used in his experiments-in
violation of ethical canons requiring that they be donated-and lied
about it. Then came word that some of the photographs depicting the stem
cell lines that had accompanied Hwang's 2005 paper were duplicates, not
originals. But this didn't seem too serious. Science claimed it was a
production error.
Shortly after that, however, came
rumors, followed by open accusations, that Hwang had committed research
fraud. A junior researcher said that rather than Science being to blame
for publishing the wrong photos, Hwang had actually forced him to submit
duplicates to make it appear that his experiments had succeeded beyond
their actual merit. Another of Hwang's colleagues claimed that the
second experiment had required hundreds more eggs than reported. If
true, it would mean that the egg efficiency problem with human
therapeutic cloning remains unsolved.
But this was all a prelude to the
real drama: On December 15, Roh Sung Il, one of Hwang's 2005 Science
coauthors, charged that 9 of their 11 stem cell lines were faked, and
that the remaining two lines might not exist at all. South Korean
scientists, academics, and media clamored for independent verification
of all of Hwang's work. At first, Hwang's lab stonewalled. Then Hwang
held a press conference, and matters became even more confused.
His responses were chaotic, his story
continually evolving. He denied faking the research. But he also
acknowledged that only three of the embryonic stem cell lines had passed
a necessary test to prove their viability. Then, sounding like Captain
Queeg, he claimed that he was the victim of a nefarious plot in which
someone, somehow, had switched his cloned stem cell lines with embryonic
stem cells derived from in vitro fertilization embryos. Finally, he
asserted some of the stem cell lines had been destroyed by fungi, but
that he was thawing five frozen samples to prove he had actually created
cloned embryos and derived stem cells from them.
Last Friday, however, all pretense of
innocence was dropped, when an investigatory panel from Hwang's
university declared that at least 9 of the 11 stem cell lines were
faked. (The other two are still under investigation.) The ruse
apparently involved splitting an original cell sample into different
test tubes and then claiming one cell line was from the patient and one
from a clone. In this way, Hwang somehow convinced one of the world's
most prestigious journals-and through it, the world-that he was a
historic figure in science. Hwang resigned his university post in
disgrace.
Hwang's implosion leaves the field of human cloning research in a state of meltdown. Their poster boy is at best a liar, at worst a fraud and a charlatan who never created human clones at all.
This debacle raises several
interesting questions: What does it tell us about the thoroughness of
the peer review process? Why were younger South Korean scientists able
to discover Hwang's missteps when the presumably more seasoned peer
reviewers for Science failed? Will the American media take a cue from
their courageous counterparts in South Korea, who pursued this story
until it cracked, and finally bring skepticism to their coverage of
biotechnology? More to the point, will the adult/umbilical cord blood
stem cell successes that have emerged one after the other in recent
years finally receive the attention they deserve in the mainstream
press, which has been so intoxicated with embryonic research as
virtually to ignore nonembryonic breakthroughs?
Don't count on it. The pro--cloning
political forces, and their media allies, recognize the potential of the
Hwang fiasco to damage their cause, so they have quickly regrouped and
begun to furiously spin the story. The same voices that not long ago
railed against President Bush's stem cell funding policies for
supposedly allowing America to fall behind the cutting--edge research in
South Korea, now indignantly blame Bush for creating a
hyper--competitive atmosphere that led to Hwang's failures. "Ethics can
get forgotten as other nations and private companies race to fill the
void left by the president's reluctance to fund stem cell research,"
wrote bioethicists Arthur Caplan and Glenn McGee in the Albany Times
Union. "Only a properly funded U.S. stem cell research program will
guarantee oversight and the protection of all involved."
That might possibly be true if
scientific fraud were the only ethical problem associated with the human
cloning agenda. But it isn't. Indeed, the bioethicists should ponder how
science's core values of integrity and objectivity are being corroded by
the passionate political pursuit of a legal license to clone.
For years, human cloning has been
promoted through propaganda techniques of misrepresentation,
exaggeration, and false hope for the suffering. Take the profoundly
deceptive $35 million political campaign that last year convinced
California voters to pass Proposition 71, authorizing the state to
borrow $3 billion to subsidize research into somatic cell nuclear
transfer cloning and embryonic stem cells. In order to induce wary
voters to endorse billions more in debt despite the red ink flowing
catastrophically out of California's coffers, proponents promised that
the state would one day garner a bounteous return from royalty and tax
payments, perhaps eventually recouping all the money borrowed to fund
the initial research. (Voters should have asked themselves why, if this
were true, the state's numerous venture capitalists hadn't been clever
enough to fork over the $3 billion.)
Thus Robert Klein, the driving force
behind the initiative and now head of the California Institute for
Regenerative Medicine, assured voters that universities and private
firms receiving grants would share $1 billion or more in royalties with
the state.
But, as reported by the San Francisco
Chronicle and elsewhere after the election, it now appears that little,
if any, royalty money will ever be returned to the state. "What Klein
knew before the election was that such royalty--sharing by the state
might be hampered by federal regulations, according to an attorney who
helped Klein draft the initiative," the Chronicle reported. "Yet he
didn't tell voters."
That wasn't all. When opponents of
Proposition 71 asserted in the official ballot arguments that the
initiative would subsidize human cloning, the pro--71 campaign sued to
prevent the argument from being mentioned in the state's voter election
guide-even though the initiative explicitly created a state
constitutional right to conduct human somatic cell nuclear transfer, the
scientific name for a human cloning technique. (The judge saw right
through the ruse, and ruled that human cloning was at the heart of the
initiative.)
Then there is the ongoing hype about
the medical potential of cloning, which reached cruel heights in the
wake of President Reagan's death from Alzheimer's disease. Using the
widespread public mourning for Reagan as a backdrop, human cloning
advocates argued that Alzheimer's could be cured if only the impediments
to federally funded embryonic stem cell research were pushed out of the
way.
In fact, though, Alzheimer's disease
is extremely unlikely to be effectively treated with stem cells, whether
cloned or natural. As Washington Post science reporter Rick Weiss
allowed in a June 10, 2004, article, "the infrequently voiced reality,
stem cell experts confess, is that, of all the diseases that may someday
be cured by embryonic stem cell treatments, Alzheimer's is among the
least likely to benefit." This is because Alzheimer's is a whole brain
disease that "involves the loss of huge numbers and varieties of the
brain's 100 billion nerve cells-and countless connections, or synapses,
among them."
If stem cells have little "practical
potential to treat Alzheimer's," why do proponents of cloned--embryo
research continue to invoke a cure for Alzheimer's in their sales
pitches? Weiss quoted Ronald D.G. McKay, a stem cell researcher at the
National Institute of Neurological Disorders and Stroke: "To start with,
people need a fairy tale. Maybe that's unfair, but they need a story
line that's relatively simple to understand."
So where are we in the cloning
debate? At this point, we don't know whether human cloning has been
successfully accomplished or not. We don't know whether embryonic stem
cells have been derived from cloned embryos. We don't know to what
depths the dishonesty of the seemingly most successful researcher in the
field actually descended.
We do know that cloning proponents in
this country are avid in their desire for billions in federal and state
money to pay for morally problematic and highly speculative research
that the private sector generally shuns. And we do know that some
advocates of this public policy agenda are more than willing to play
fast and loose with the facts in order to get their way. In short, the
human cloning agenda is falling into public disrepute-and for that,
proponents of the agenda have no one to blame but themselves.
