The Great Stem Cell Hoax
The research promises results about a half century from now.
Aug 20, 2001, Vol. 6, No. 46 • By CHARLES KRAUTHAMMER
SANITY AND PRUDENCE combined to produce a great victory on July 31 when the House of Representatives overwhelmingly defeated—the margin was over 100 votes—the legalization of early human embryonic cloning. But the fight is not over. The Senate needs to act as well.
Before it does, however, it is worth preparing oneself for the gale-force hype that Senate advocates will unleash in defense of the indefensible. One has only to look at the debate on the floor of the House to see the extraordinary lengths to which the biotech industry and its allies in Congress will go to sell the deliberate creation of embryo factories for the sole purpose of exploiting and then destroying them.
While the media have been snooping under Gary Condit’s bed, they have missed the real scandal of the season, the unconscionable deployment of fantasy and false hopes by advocates of "therapeutic" cloning for the production of stem cells. The basic premise—cure of the incurable—was stated by a Newsweek cover a month ago: "There’s Hope for Alzheimer’s, Heart Disease, Parkinson’s and Diabetes. But Will Bush Cut Off the Money?" The theme has been echoed and reechoed nowhere more than in Congress.
The cosponsor of a permissive cloning bill, Peter Deutsch (D-FL), said this about the opposing bill totally banning cloning: "No one knows who is going to get Alzheimer’s or Parkinson’s or cancer. . . . What this legislation would do would be to stop the research . . . so that you could survive, so that someone who is a quadriplegic could walk, so that someone who has Alzheimer’s . . ." He trailed away. You get the drift. The lion will lie down with the lamb.
Nancy Pelosi (D-CA), with characteristic subtlety: "Mr. Speaker, the National Institutes of Health and Science hold the biblical power of a cure for us."
Zoe Lofgren (D-CA): "If your religious beliefs will not let you accept a cure for your child’s cancer, so be it. But do not expect the rest of America to let their loved ones suffer without cure."
Jerrold Nadler (D-NY): "We must not say to millions of sick or injured human beings, ‘go ahead and die, stay paralyzed, because we believe the blastocyst, the clump of cells, is more important than you are.’ . . . It is a sentence of death to millions of Americans."
Anna Eshoo (D-CA): "As we stand on the brink of finding the cures to diseases that have plagued so many millions of Americans, unfortunately, the Congress today in my view is on the brink of prohibiting this critical research."
Eshoo gets the prize. The brink? The claim that cloning, and the stem cells it might produce, is on the verge of bringing a cure to your sick father with Alzheimer’s or your debilitated mother with Parkinson’s is a scandal. It is a cruel deception perpetrated by cynical scientists and ignorant politicians. Its purpose is clear: to exploit the desperation of the sick to garner political support for ethically problematic biotechnology.
The brink? Cloning animals, let alone humans, is so imperfect and difficult that it took 277 attempts before Dolly the sheep was cloned. Scientists estimate that the overall failure rate for cloning farm animals is 95 percent or greater. New experiments with cloned mice have shown gross deformities. And here is the worst part. We have no idea why. We understand little about how reprogrammed genes work. Scientists don’t even know how to screen with any test for epigenetic abnormality.
In other words: Even if you could grow embryonic stem cells out of grandma’s skin cells, we have no idea yet how to regulate and control these cells in a way to effect a cure. Just growing them in tissue culture is difficult enough. Then you have to tweak them to make precisely the kind of cells grandma needs. Then you have to inject them and hope to God that you don’t kill her.
We have already had one such experience, a human stem cell experiment in China. Embryonic stem cells were injected into a suffering Parkinson’s patient. The results were horrific. Because we don’t yet know how to control stem cells, they grew wildly and developed into one of the most primitive and terrifying cancers, a "teratoma." When finally autopsied—the cure killed the poor soul—they found at the brain site of the injection a tumor full of hair, bone and skin.
Let’s have a little honesty in both the cloning and stem cell debates. Stem cell research does hold promise for clinical cures in the far future. But right now we’re at the stage of basic science: We don’t understand how these cells work, and we don’t know how to control them. Because their power is so extraordinary, they are very dangerous. Elementary considerations of safety make the prospect of real clinical application distant.
