Who cares about real Parkinson's patients when there's a Brave New World to sell?
RON REAGAN'S SPEECH at the Democratic convention last night was expected to urge expanded funding for stem cell research using so-called "spare" embryos--and to highlight these cells' potential for treating the Alzheimer's disease that took his father's life.
He did neither. He didn't even mention Alzheimer's, perhaps because even strong supporters of embryonic stem cell research say it is unlikely to be of use for that disease. (Reagan himself admitted this on a July 12 segment of MSNBC's Hardball.) And he didn't talk about current debates on funding research using existing embryos. Instead he endorsed the more radical agenda of human cloning --mass-producing one's own identical twins in the laboratory so they can be exploited as (in his words) "your own personal biological repair kit" when disease or injury strikes.
Politically this was, to say the least, a gamble. Americans may be tempted to make use of embryos left over from fertility clinics, but most polls show them to be against human cloning for any purpose. Other advanced nations--Canada, Australia, France, Germany, Norway--have banned the practice completely, and the United Nations may approve an international covenant against it this fall. Many groups and individuals who are "pro-choice" on abortion oppose research cloning, not least because it would require the mass exploitation of women to provide what Ron Reagan casually calls "donor eggs." And the potential "therapeutic" benefits of cloning are even more speculative than those of embryonic stem cell research--the worldwide effort even to obtain viable stem cells from cloned embryos has already killed hundreds of embryos and produced exactly one stem cell line, in South Korea.
But precisely for these reasons, Ron Reagan should be praised for his candor. The scientists and patient groups promoting embryonic stem cell research know that the current debate on funding is a mere transitional step. For years they have supported the mass manufacture of human embryos through cloning, as the logical and necessary goal of their agenda, but lately they have been coy about this as they fight for the more popular slogan of "stem cell research." With his speech Reagan has removed the mask, and allowed us to debate what is really at stake.
He claimed in his speech, of course, that what is at stake in this debate is the lives of millions of patients with devastating diseases. But by highlighting Parkinson's disease and juvenile diabetes as two diseases most clearly justifying the move to human cloning, he failed to do his homework. These are two of the diseases that pro-cloning scientists now admit will probably not be helped by research cloning.
Scottish cloning expert Ian Wilmut, for example, wrote in the British Medical Journal in February that producing genetically matched stem cells through cloning is probably quite unnecessary for treating any neurological disease. Recent findings suggest that the nervous system is "immune privileged," and will not generally reject stem cells from a human who is genetically different. He added that cloning is probably useless for auto-immune diseases like juvenile diabetes, where the body mistakenly rejects its own insulin-producing cells as though they were foreign. "In such cases," he wrote, "transfer of immunologically identical cells to a patient is expected to induce the same rejection."
Wilmut's observations cut the ground out from under Ron Reagan's simple-minded claim that cloning is needed to avoid tissue rejection. For some diseases, genetically matched cells are unnecessary; for others, they are useless, because they only replicate the genetic profile that is part of the problem. (Ironically, for Alzheimer's both may be true--cloning may be unnecessary to avoid tissue rejection in the brain, and useless because the cloned cells would have the same genetic defect that may lead to Alzheimer's.) Reagan declared that this debate requires us to "choose between . . . reason and ignorance," but he did not realize which side has the monopoly on ignorance.
That ignorance poses an obstacle to real advances that are right before our eyes. Two weeks before Ron Reagan declared that a treatment for Parkinson's may arrive "ten or so years from now," using "the material of our own bodies," a Parkinson's patient and his doctor quietly appeared before Congress to point out that this has already been done. Dennis Turner was treated in 1999 by Dr. Michel Levesque of Cedars-Sinai Medical Center in Los Angeles, using his own adult neural stem cells. Dr. Levesque did not use the Rube Goldberg method of trying to turn those cells into a cloned embryo and then killing the embryo to get stem cells--he just grew Turner's own adult stem cells in the lab, and turned them directly into dopamine-producing cells. And with just one injection, on one side of Turner's brain, he produced an almost complete reversal of Parkinson's symptoms over four years.
Turner stopped shaking, could eat without difficulty, could put in his own contact lenses again, and resumed his avocation of big-game photography--on one occasion scrambling up a tree in Africa to escape a charging rhinoceros.
Amazingly, while this advance has been presented at national and international scientific conferences and featured on ABC-TV in Chicago, the scientific establishment supporting embryonic stem cell research has almost completely ignored it, and most news media have obediently imposed a virtual news blackout on it. That did not change even after the results were presented to the Senate Commerce Subcommittee on Science, Technology and Space this month. Pro-cloning Senators on the panel actually seemed angry at the witnesses, for trying to distract them from their fixation on destroying embryos.
Turner also testified that his symptoms have begun to return, especially arising from the side of his brain that was left untreated, and he would like to get a second treatment. For that he will have to wait. Dr. Levesque has received insufficient appreciation and funding for his technique, and is still trying to put together the funds for broader clinical trials--as most Parkinson's foundations and NIH peer reviewers look into the starry distance of Ron Reagan's dreams about embryonic stem cells.
But hey, who cares about real Parkinson's patients when there's a Brave New World to sell?
Richard Doerflinger is Deputy Director of the Secretariat for Pro-Life Activities, U.S. Conference of Catholic Bishops.
And, please, don't clone Ron!
Anyone who attempts to clone a human being ought to be locked in a room with three other "hims" for the rest of his life.
A couple of rhetorical questions for these folks.
What kind of embryo do you use?
What is an embryonic human?
His persona is so cold I get frostbite just watching him
In Ron Reagan's mind, opposing stem cell research on religious grounds amounts to being ignorant.
Belief in God=ignorance.
And his father not yet two months in his grave.
