The Final Frontier
Irv Weissmans home is about 20 minutes from Stanford University, hidden from the road by a tall stand of trees. Inside, all of the rooms are spacious, but the living room is more so. The ceiling is high and broad-beamed; the furniture, Western chic: chairs hewn from tree branches, tables built from tree trunks. The couch is a curving affair that looks a little like a giant, gold earthworm caught in a pillow fight. Spread out in front of the fireplace is a bearskin rug. This bear has seen better days. Irv Weissman is talking about how those days came to an end.
We ate him. Rare. We were a little nervous about it because most wild bears have trichinosis, but what the hell.
Irv Weissman doesnt look the bear-eating sort. Hes of middle height, middle weight, mildly balding, with fine clothes, a jovial aspect and a long, wispy beard. He is a scientist, yet looks more like a Russian poet or an aged food critic. Beneath this exterior, however, hes just a boy from Montana -- the grandson of a Jewish homesteader who, upon arriving at Ellis Island, walked across the country and tried his hand at mining, fur trapping and eventually opened a hide shop that became a group of hardware stores; the son of a man who, when wounded by a knife-wielding assailant, was tough enough to fight back and beat the man silly -- so silly it made the papers. Which is to say Weissman comes from a culture of bear eaters.
So why is he living among Stanford academics and not in Great Falls, Montana, with other bear eaters? When Weissman was 10, he read Paul de Kruifs book Microbe Hunters, which describes the work of Ehrlich, Pasteur and other early bacteriologists. He quickly decided science was more interesting than hardware. By the time he was in high school, he worked at a lab in Great Falls doing transplantation research. He published two papers, on cancer and transplantation, before he was 18.

Weissman entered Dartmouth College but found that he didnt fit in with either the East Coast Jews or the East Coast non-Jews. After two years he transferred back to Montana State University in Bozeman, where he could study premed without worrying about how a Jew from Montana was supposed to behave on the East Coast. He left the state again in 1960, entered Stanford Medical School and one way or another has stayed for the duration. Currently, hes a professor of cancer biology and a professor of pathology. In 2002, he was voted California Scientist of the Year.
True to his roots, Weissman approaches science like a Montana boy -- charting unexplored realms, pioneering in the lab. His early work focused on how the cells of the immune system fight cancer. He spent much of his time studying the relationship between blood cells, cancer and radiation. Because of the research that emerged after the explosion of the atomic bombs over Hiroshima and Nagasaki, scientists knew that exposing the human body to radiation wiped out both blood cells and cancer cells.
They also knew that after irradiating the body (chemotherapy), you could perform a bone-marrow transplant using marrow from a healthy, cancer-free donor and that something in that new bone marrow would begin producing all sorts of cells. We knew there must exist a very rare cell inside the bone marrow that would give rise to all types of cells -- but this was only a theory, says Weissman. No one had ever isolated that cell. I started wondering how to tease it out from all the others.
This was in the late 60s. For years, Weissman worked in his lab sorting cells. An easy way to think about this is that he took mouse blood and poured it through a long series of strainers. With each pass a different kind of cell was removed. Out came the T cells, out came the B cells, the red blood cells, the white blood cells and on and on until there was only one kind of cell left. Finally, in 1988, Weissman managed to do something that no one else had ever done, something that most people didnt even think was possible: He isolated a cell that gave rise to all other kinds of blood cells, a blood-forming stem cell. He also became one of the first people on the planet to realize the promise of what he had done. This has made him a controversial man.
If youve been living inside a Himalayan cave, perhaps you havent heard about stem cells, but otherwise the gist has been hard to miss. Scientists from all fields have been harping on stem-cell research as the most important directed medical-research effort ever. When Irv Weissman started working with mouse cells, he realized, nearly from the beginning, that he was onto something that could potentially save millions of lives. I knew that if I could ever do this in humans, he says, I would be able to use chemotherapy to wipe out cancer cells and then transplant in new stem cells that would be completely disease free.
Cancer wasnt the only thing on his mind. Weissman knew that a great number of the bodys terrible diseases -- Alzheimers, diabetes, Parkinsons, others -- are caused by misbehaving cells and that it might be possible to remove the bad cells and replace them with normally functioning stem cells. In America, 1.3 million people have cancer; 4 million have Alzheimers; 1.5 million have Parkinsons; 17 million have diabetes. This doesnt include those in need of a new kidney or bladder or spinal cord -- which stem cells could possibly be used to grow. Thats a lot of lives to save.
What Irv Weissman didnt understand at first is that his own government could politicize these stem cells and decide that potentially saving millions of lives was a bad idea. What he didnt understand then, but has come to understand since, is that without his rugged Montana perseverance, he might not ever get the chance to save these millions of lives.
R. Alta Charo, a professor of law and medical ethics at the University of Wisconsin, Madison, who served on Bill Clintons bioethical council and who has been a part of this discussion since nearly the beginning, likes to say, The stem-cell debate is a debate about everything but what its about. Which is to say that the stem-cell debate is not, actually, about stem cells.
Really, it is about George Bush trying to win a second-term election after not actually winning the first. Its about the son not making the same mistakes as the father and losing the religious right. And its about the religious right trying like hell to pave the way for the Supreme Court to take away a womans right to have an abortion.
A discussion of this requires a little more background on the five ways scientists obtain stem cells. The principal method is through a process called somatic cell nuclear transfer, which well get to in detail soon. But for now well concentrate on the other four. One of those ways is through parthenogenesis, the Greek word for virgin birth. In this process, an unfertilized egg is tricked into cell a division and then mined for stem cells. Another way is to take one of the existing 60 cell lines and form another cell type to create new lines. Both of these ideas are exciting, but no one really knows if or how well either will work, and so, for now, both are off the radar.
In the remaining two methods, fetal stem cells are culled from aborted fetuses and embryonic stem cells are removed from unused embryos taken from in-vitro fertilization clinics. Because of these methods, stem cells sit smack in the middle of Americas reproductive-rights debate. In fact, some have argued, the debate over the process of culling stem cells is the best thing to happen to the religious rights anti-abortion crusade in decades.
Every year since Roe v. Wade thousands of women have been having abortions, explains Charo. Thats 30 years, an entire generation of women who have experienced the ability to choose. Thats a huge demographic imperative. The evangelical right is fighting against a culture of tolerance for embryonic destruction, and theyre losing that fight every time a woman knows she can make a choice. The conflation of cloning and stem-cell research has allowed [the religious right] to argue for the embryo in the context of a technology -- reproductive cloning -- that has a near-universal shock value.
Its a tricky thing to try and overturn a Supreme Court decision like Roe v. Wade. Nonetheless, for 30 years, foes have been chipping away at it. One of the main reasons it has held fast hinges on this idea: A human embryo does not have the same rights as a human being. To overturn the decision you need at least a couple of things. One is a pro-life Supreme Court (which is a whole other can of worms, but it starts with what we just got -- a pro-life Senate). The other is evidence that supports the idea that the American public now feels that embryos are people too.
For the benefit of reporters and congressmen locked in this debate, Irv Weissman does an interesting experiment. He walks up to strangers on the street and asks them to draw an embryo. Invariably, he says, every time, without fail, they draw a fetus with a face. A fetus with a face is not an embryo. An embryo is a scientific term used to describe the period of time from when a zygote is formed until the time it begins to have discernible organs. Meaning, specifically, that the word embryo was created to distinguish it from a fetus. It is nothing like the cartoons that people draw. In fact, under a microscope, an embryo is even less spectacular than stem cells.
If you want to prove to the Supreme Court that both the scientific community and the American public have changed their minds about the status of the embryo, then you need a series of precedents. These are not just legal precedents; these are psychological precedents as well. The high court would need to decide that the countrys opinion has changed, and to do this you would need to show that in related -- but not abortion-specific -- departments the embryo is now being afforded the same protections as both fetus and adult.
To this end, Bush has stacked a bevy of anti-choice judges in the lower courts and appointed an anti-choice attorney general in John Ashcroft. And while you could argue that this is just party politics -- and it is -- behind the obvious partisan court appointments there are covert anti-choice precedents being set.
Last October, the Bush administration changed the section of the Health and Human Services charter that regulates research done on human subjects. This legislation exists so that if you volunteer for a sleep study, you dont end up dead. The old charter granted legal protection to adults and fetuses. The new version protects embryos as well.
For a long time, womens groups have been lobbying the government to provide health care for pregnant women. To this end, the Bush administration extended the reach of the State Childrens Health Insurance Program to cover both embryos and fetuses but, oddly, not pregnant women. So, while pregnant women still can be without health care, the groups of cells dividing in their uteruses now have more health coverage than their uninsured mothers.
Bush has also lobbied hard for a ban on partial-birth abortions, which technically eliminates the already rare late-term abortions but in effect criminalizes the procedure. Bush also reinstated Ronald Reagans gag rule that bars federally funded family planners from discussing abortion as an option or from providing abortion services.
The point of these things, says Allison Herwitt, director of government relations for the National Abortion and Reproductive Rights Action League is to weave embryonic rights into law. These are not individual occurrences. These are a well-crafted strategy to end legal abortions. And one of the next steps in that strategy is to outlaw stem-cell research -- not because the research itself is in question, but because banning the way that research is conducted can help them to achieve their true goal.
Under a microscope, stem cells arent much to look at. They grow in clusters and even when magnified 10 times are individually smaller than pinheads. They look like slimy, slightly metallic grapes. Under a microscope, it would be easy to mistake them for something utterly inconsequential, like tadpole snot.
Its almost funny, says Larry Goldstein, that something so dull-looking could cause such a fuss.
Goldstein, another scientist in the middle of this stem-cell storm, is a plain-spoken, energetic man in his late 40s. He has gray hair and a long, handsome face. As an investigator and professor of cellularmolecular medicine at the University of California, San Diego, he oversees a lab that employs 23 people and thousands of mice. Both mice and men are working toward answers to the same set of questions: how biological complexes (proteins, lipids and organelles) move through the neurons and brain cells.
He wants to know these things because he thinks the answers will go a long way toward providing a cure for Alzheimers, Huntingtons chorea and Lou Gehrigs disease. To get the answers, he needs stem cells.
Stem cells are the bodys rawest materials. From them, developing embryos build all other cells that eventually form the body. Unlike specialized cells that can only form one thing -- a liver, say, or a nose -- stem cells can change into any other kind of cell.
Currently, much of Goldsteins work involves non-human-derived stem cells, which are not technically a point of contention. But five years from now, if I want to actually cure these diseases, Ill need access to human embryonic stem cells, and I want to make sure theyre available.
The issue of stem-cell availability is at the root of a war of terminology. Both sides are using big words, and some of those words have frightening connotations. Ignorance is part of the problem. Because of the complexity involved, the media often choose brevity over accuracy, and the combatants fuel the war by co-opting partially a defined words to their own ends.
Cloning is one of the biggest bombs in this terminology war. You have to understand something, Weissman says. Cloning has as many meanings to a scientist as ice to an Eskimo or love to Oprah Winfrey. On the other hand, cloning, to a man like Leon Kass, means only one thing: producing carbon-copy human beings.
Leon Kass is yet another controversial man at the center of this battle. He is a University of Chicago bioethicist who believes that life begins at conception and who now heads up President Bushs Council on Bioethics. Time magazine called him the presidents ethics cop. The council is charged with advising Congress and the administration on stem cells. A few years ago Kass wrote a now-famous article for The New Republic titled Preventing a Brave New World or Why We Should Ban Human Cloning Now. He explained the aforementioned procedure called somatic cell nuclear transfer (SCNT), the principal means of obtaining stem cells, and disingenuously equated that process with the cloning of people. Here are a few lines taken from Kass article:
What is cloning? Cloning, or asexual reproduction, is the production of individuals who are genetically identical to an already existing individual. The procedures name is fancy -- somatic cell nuclear transfer -- but its concept is simple. Take a mature but unfertilized egg; remove or deactivate its nucleus; introduce a nucleus obtained from a specialized (somatic) cell of an adult organism. Once the egg begins to divide, transfer the little embryo to a womans uterus to initiate a pregnancy. Since almost all the hereditary material of a cell is contained within its nucleus, the re-nucleated egg and the individual into which it develops are genetically identical to the organism that was the source of the transferred nucleus.
Scientifically, Kass is correct, except -- and this is a big except -- SCNT stops short of transplanting that egg into a womans uterus. What Kass knows, but chooses not to acknowledge here, is that once that new egg begins to divide, one of two things can happen. The first is it could be implanted into a womans uterus and develop those dreaded carbon copies. This process is called reproductive cloning, and almost every mainstream scientist the world over, including Weissman and Goldstein, opposes it.
The second thing that could happen is what opponents of this work like to call therapeutic cloning. Weissman prefers nuclear transplantation to produce stem cells. Either way, in this second scenario, once that very early embryo (a cluster of 100 or so cells called a blastocyst) is formed, there is a two-week window during which the stem cells are extracted. In doing this, the embryo becomes unsuitable for manufacturing the dreaded clones, or any other viable human form for that matter. If you wanted to create another human being, you would have about as much luck successfully implanting that enucleated embryo into a womans uterus as you would have growing a Buick by planting an engine block in the ground.
Kass apparent attempt to equate SCNT with the production of cloned individuals becomes egregious because his knowledge and opinions are being used to enact legislation that will then affect the entire country.
A clear indication of Kass sway took place in the spring of 2001, when a pair of cloning bills was introduced, one in the House and one in the Senate. The original House bill went nowhere, but it was quickly rewritten and reintroduced by Dave Weldon (R-Florida). On July 31, 2001, after three hours of debate during which conservatives spoke about eugenics, commodifying humanity, the peril of private-industry control over the human genome, the need for science to operate within social and ethical norms, and -- of course -- the Nazis, the House of Representatives passed the Weldon Bill 265 to 162.
The bill (and its sister Senate bill, which was introduced by Kansas Republican Sam Brownback and is known as the Brownback Bill) seeks to outlaw all forms of cloning -- both reproductive and therapeutic -- with severe penalties of up to a $1 million and 10 years in prison for either doing research or receiving medical treatment based on that research. This means that if the French invent a stem-cell-based cure for Alzheimers and you go to France and receive treatment and try to re-enter the United States, youre not passing go, youre going straight to jail. The only good news is that since your Alzheimers is now cured, youll remember the whole experience.
On August 9, 2001, President Bush, in his first address to the nation, echoed Kass fear-mongering and followed his lead: We have arrived at that brave new world that seemed so distant in 1932, when Aldous Huxley wrote about human beings created in test tubes in what he called a hatchery.
Bush then issued an executive order restricting federal research money to the 60 previously harvested stem-cell lines. These lines were cultivated between 1998, when human embryonic stem cells were first isolated, and the moment Bush put the kibosh on further work. Never mind that the majority of these lines have not been studied enough to know if theyre actually safe for use in humans.
But the real problem with them, says Weissman, is that all 60 lines come from people who utilize in-vitro fertilization clinics. Part of the problem is IVF clinics serve a very specific segment of the American population. The stem-cell lines taken from IVF clinics are cell lines taken from rich, white, infertile people. We have no idea if stem cells possess ethnic, genetic variation -- and they might. One of the fundamental principles of bioethics is called distributed justice. That means when scientists work on medical cures, they want to develop cures for everyone -- not just for rich, white, infertile people.
In other words, scientists want to study a rainbow coalition of stems cells, but by limiting research to existing lines, compassionately conservative George Bush has created a stem-cell policy much like his tax cut: The rich get richer, the poor get screwed.
Spend five minutes with Jerry Zucker and youll think that his life could have gone either way. One wrong turn and he would have ended up still working the coat check and living with his mother at 50. He wears cardigans. In conversation, his voice is several decibels below soft-spoken. Words hang up on his lips. He has soft features, bushy eyebrows, errant hair and, all told, looks like someone in constant, mild pain. The one thing he doesnt look like, and this may be his great genius, is Hollywood royalty, or at least its court jester.
Zucker created his own brand of movies, a genre of wack-job comedy that began with Kentucky Fried Movie, was perfected in Airplane! and which includes the Naked Gun and Police Squad franchises. He also a made a sweet movie about a dead guy, a live woman and a pottery fetish called Ghost.
Zucker Productions is a few modest rooms located in a peach-walled building in Santa Monica. Zuckers movies are such flamboyant affairs, its hard to imagine them beginning in rooms this small.
Its also hard to imagine Zucker as the political type. Though he attended the University of Wisconsin from 1968 to 1972, when Madison was a radical hotbed (the legendary Vietnam protest documentary The War at Home was filmed then and there), Zucker was, by his own admission, never much more than a weekend rioter. His politics are still middle-of-the-road.
Since then, not much has changed. Yet everything has changed. In 2000, Zucker found out that his 11-year-old daughter, Katie, had juvenile diabetes. Immediately, he began researching the disease and hunting for hope. In the summer of 2001, he started hearing about something called stem cells and how they might be able to not just provide better treatment, but actually cure the disease. That summer he also heard that the Weldon Bill had passed, that President Bush was limiting research to 60 mostly moribund cell lines and that the Brownback Bill was heading for a vote in the Senate where only seven members were in favor of keeping the research legal.
As a director, says Zucker, I tend to be calm. I dont want to be another Hollywood maniac. I try not to get carried away or lose my cool. What was going on with stem cells made me very angry.
Through sad coincidence, Zucker and his wife, Janet, had gotten to know Douglas Wick (the producer of Gladiator, Stuart Little and Working Girl), and his wife, Lucy Fisher, the former vice chairman of Columbia TriStar Motion Picture Group. Wick and Fisher also have a daughter with juvenile diabetes. The foursome had been active in the Juvenile Diabetes Research Foundation, but wanted to be at the forefront of the stem-cell debate and felt that if they started their own organization they could not only act quickly, they could bring the full weight of Hollywood to bear on the situation.
Together they hired a lobbyist and went to Washington. They took their daughters and Caltech stem-cell biologist David Anderson along. They called this new group CuresNow. This was in the summer of 2002. To give you an idea of how strong the love affair between D.C. and Hollywood is, what did CuresNow do to get in to see senators?
Um, says Zucker, I just called up and said this is Jerry Zucker.
They looked at their trip as an educational crusade. They punched below the waist. We would walk in to a senators office with my daughter and her insulin pump attached to her belt and ask them what was more important -- my daughters life or the life of a couple of cells?
In a sense, CuresNow was fighting against the work of its founders business. In the minds of many, stem cells are directly linked to cloning, and the public perception of cloning is directly linked to Hollywood. We spent the better portion of the 20th century making mad-scientist movies, says Zucker. One of the first senators we met -- I cant tell you his name -- went on and on about how if we let this technology go forward someone will try to create a new Hitler. How much of that is real fear and how much of that is Hollywood?
As they suspected, most of the politicians didnt really know what they were voting on. The Hollywood crew explained things slowly, and slowly began making headway. One of their early converts, who remains their strongest ally on the right, was Utah Republican and pro-life advocate Orrin Hatch. Centenarian Strom Thurmond joined their cause. Senate Minority Leader Tom Daschle agreed not to put the Brownback bill on the floor for a vote until CuresNow had a chance to talk to everyone who would listen.
Hatch, alongside several other senators (Feinstein, Kennedy and Specter), introduced his own bill that banned reproductive cloning but allowed therapeutic cloning. Neither his bill nor Brownbacks could gather the votes needed to pass. Instead, Brownback tried attaching anti-cloning to several other bills, but CuresNow was making headway. The word was getting out, and none of the anti-cloning amendments have met with success. Currently, 60 senators favor stem-cell research, and the Senate vote is still pending.
Since the recent Republican gains in Congress, CuresNow knows that its Washington work is not done. But Zucker and company are spending an equal amount of energy in California because its here that lines are being drawn and the first major battle for stem-cell research is being fought.
California is the countrys biotech leader, says Zucker. We have brilliant scientists and a receptive state government. I want to see California as a safe haven for stem-cell research. We have a history of leading the nation in fights such as this. We have a great chance to add to that history.
The 10th Amendment to the U.S. Constitution reads: The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. Politically, this is the typically Republican turf known as states rights. It exists as a barrier to top-down, Washington-mandated policy. It is the legal reason California was able to legislate lower emission standards than the national standards mandated by the Clean Air Act. The rest of the nation followed Californias anti-emission movement; car manufacturers, to their dismay, had to comply. California Democrats had used one of the Republicans favorite weapons -- states rights -- to spark a state-by-state subversion of the GOPs big-auto agenda.
This tactic doesnt always work. In 1996, California passed Proposition 215, making marijuana available with a note from your doctor, like any other prescription drug. In the ensuing years, nine other states legalized medical marijuana. George W. Bush promised in a 2000 campaign speech to leave medical marijuana as a states-rights issue, saying, inimitably, I believe each state can choose that decision as they so choose.
But in May of 2001, the U.S. Supreme Court in U.S. v. Oakland Cannabis Buyers Cooperative ruled against the 10th Amendment, and in 2001 the Drug Enforcement Agency started raiding Californias buyers clubs and growers organizations, confiscating wares and imprisoning owners.
It doesnt take an astute political analyst to realize that two of the engines driving the Republican Party are economics and morality. There are many different ways of looking at the conflicting tales of emissions and medical marijuana. The least cynical is to believe that the country was ready for cleaner air and not ready for legalized drug use. A more jaundiced view says that pollution laws had two things going for them -- they didnt contradict federal law and, since Californians buy more cars than anyone else, compliance carried an enormous economic incentive. Medical marijuana, on the other hand, goes against federal law and also lacks an economic impetus since you cant tax its sale. Most important, it offends the moral standards of the right.
The California biotech industry is a huge economic impetus. In 2001, when President Bush limited stem-cell research to the 60 previously existing stem-cell lines, he effectively yanked a huge segment of biotech research to a dead halt. Moneys were drying up, and Americas top scientists began leaving the country and moving to places with fewer restrictions -- an effect that analysts quickly dubbed the brain drain.
Almost immediately following Bushs August announcement, University of California at San Francisco stem-cell pioneer Roger Pedersen packed his bags and lab and moved to England, where stem-cell research is permitted. Other countries, including Israel, Japan, France and Australia, have made themselves friendly to the work. Last year, Singapore took an even more aggressive stance, declaring itself a center for stem-cell study, breaking ground on a $15 billion research park and quickly poaching top U.S. minds including Edison Liu, once a leading researcher at Americas National Cancer Institute and now the head of Singapores new Genome Institute. Theres even talk of an international consortium for stem-cell research similar to the one that cracked the human genome.
To combat the brain drain and bring more biotech money into California, state Senator Deborah Ortiz (D-Sacramento) introduced Senate Bill 253. The bill allocates the use of state funds and private donations for stem-cell research within California.
If your idea of a senator includes gray hair, a stentorian voice, pinstripes and steely eyes, then Senator Ortiz does not fit the bill. She looks like a suburban housewife and acts like an endearing grandmother. On the day we met, she arrived carrying Greek pastries that looked like failed geometry experiments oozing filling. She is an easy woman to underestimate. One gets the feeling that she spends her days nudging legislation into law.
In her day, she has nudged quite a bit of legislation into law. In 1993, she was elected to Sacramentos City Council and fought a nasty fight for safer neighborhoods and tougher gun control. In 1996, she was elected to the state Assembly. That same year her mother was diagnosed with ovarian cancer. In the Assembly, Ortiz gave state workers a long-overdue pay raise and created a statewide after-school learning program for at-risk students. At home she became an armchair cancer specialist. I read all the studies and I read the footnotes. But there was no cure in the footnotes, and her mother died in 1999 during Ortizs first state Senate term. Knowledge led her toward advocacy. Ortiz earmarked $25 million for ovarian-cancer research, but felt that wasnt enough.
From the footnotes I came to believe that the cure for cancer has to exist at the cellular level, Ortiz says. Stem-cell research is the next wave. When she was re-elected to the state Senate in 2002, she turned her attention to stem cells. It wasnt just a cure for cancer that drove her decision. She knew that California took a $12 billion hit in the dot-com crash, and recent studies claim that the states budget deficit will exceed $35 billion in the next year and a half. On September 22, 2002, Gray Davis signed SB 253. Ortiz had nudged perhaps her biggest bill into law. California became the first state to legalize stem-cell research.
By signing SB 253, we have opened the door to important life-saving research in California, said Davis, when asked about the bill. There are strict parameters to stem-cell research built into the bill, but the possibility of some of the industrys top science researchers finding a cure to fatal diseases such as Alzheimers and Parkinsons diseases, spinal-cord injury, stroke, burns, heart diseases, diabetes and arthritis is priceless. We fully expect stem-cell research to attract world-renowned scientists to our state. Currently, there are 2,500 biomedical companies in California that employ 225,000 people. During 2000, this industry paid its employees $12.8 billion. While this life-saving research will continue to bring the necessary [private] funding into the state, it will more importantly save lives.
Almost immediately after Davis signed, other states followed Californias lead. New Jersey, Pennsylvania, Louisiana and Rhode Island have already legalized therapeutic cloning, and Massachusetts and New Mexico are considering similar proposals.
This grassroots, states-rights movement on stem-cell research presents a dilemma for Republicans. The old-school, economic Republicans are interested in free enterprise and biotechnology -- the economic imperative. The new-school, moral Republicans are interested in homogeneous morality and banning abortion. Stem cells split the two sides of the party. One of the reasons for the terminology war is that the Bush administration needs to create a cloning bogeyman in order to bridge the schism in his party. This way he appeases the moralists while doing an end run around the economists who would be rather pleased with biotech billions.
It is interesting to note that there is no Bush administration or religious-right opposition to the in-vitro fertilization process, despite the fact that in the normal course of in vitro, multitudes of embryos are destroyed. During in vitro, ova that have been extracted from a womans body are fertilized in a petri dish. On average, 20 or so embryos are created, but only one is implanted. The rest are temporarily frozen and then eventually discarded. This means that while the administration and the religious right are opposed to using those ill-fated embryos for stem-cell research, they are more than happy to turn a blind eye to their destruction in the name of pregnancy. This is because their anti-abortion legal strategies call for defining life ever earlier and ever more clinically -- as early and clinically as a dish in a refrigerator (talk about weird science). Also, they do not wish to confront sterile parents or hamper a multimillion-dollar industry.
So sure, its a tad dramatic to say that what followed SB 253 is a high-stakes poker game with states rights, Bushs second term, abortion legality, the biotech industry and medical science as major players. In less dramatic language, whats happened in California is that the two key issues driving the Republican bus have come into head-on conflict with each other, and its because Democrats have forced the issue by playing the states-rights card.
Just before Davis signed Ortizs bill into law, Andy Grove, the chairman of Intel, donated $5 million to UCSF for a stem-cell biology program. Because of Bushs restrictions, anyone wanting to do stem-cell research requires facilities that are completely unattached to anything receiving National Institutes of Health dollars -- thus separate buildings, labs, equipment and such must be constructed. The $5 million wont pay for much of that, but it was the first major private donation and a good start.
In Irv Weissmans home, on the evening of December 11, a small dinner party was held to celebrate the next step -- that being Stanfords announcement a day earlier that it plans to capitalize on $12 million of anonymously donated seed money and build a $120 million Institute for CancerStem Cell Biology and Medicine headed up by Weissman. Building on his previous research with blood-forming stem cells, the Stanford institute will initially turn its attention to discovering the stem cells that become the other major organs of the body -- that way, if these organs become cancerous, theyll have new ways to fight the disease.
Weissman does not look like a man in celebration. His movements are careful, his brow creased. He wears a chefs apron and stands at the stove, studying the goose hes been busy cooking.
Around the dinner table sits a hungry crew. Weissmans sister Lauren, once a Hollywood producer with five major films to her credit and now the executive director of CuresNow, is there. As is Lee Hood, another top scientist and the man who invented the DNA sorter that facilitated the sequencing of the human genome; and Ann Tsukamoto, a scientist with StemCells Inc.
Weissman maintains a robust wine cellar, and there are a number of prestigious bottles sitting unopened on the counter and a number sitting opened on the table. In between gobs of goose and glasses of grape, Weissman explains the focus of Stanfords new research institute.
Its not only new ways to fight the disease, he says. Thats only the first step. We also know that there are cancer-forming stem cells. If we can isolate these, we can get to the very root of every type of cancer. This would give us new, biologically specific targets for drugs. And because the institute is in this state, California will be the first place these therapies will come out. Our biotech companies will produce them, and Californians will get the first crack at these treatments.
Even this is only the tip of the iceberg. The institute plans to improve the efficiency of SCNT, and once thats done they can begin growing diseases from scratch -- which means theyll develop a fundamental understanding of how the body gets sick. So, when the Bush administration says it opposes all forms of cloning, it is, in effect, saying it opposes the best bet yet for curing cancer.
As expected, Stanfords announcement sparked a firestorm. All of the top papers and top news shows reported the story, but not one bothered to explain the tie-in between the stem cells and cancer. Instead the words human cloning got heavy play. The Associated Press was the first to cover the story, and its article began: Stanford has said its new cancer institute will conduct stem-cell research using nuclear-transfer techniques -- work that many consider to be cloning of human cells. ABC News followed suit: The president believes that the creation and destruction of embryos for the purpose of research or reproduction is morally wrong. He is against cloning of any kind and feels there are other biomedical-research avenues.
Leon Kass immediately issued a press release claiming that Stanford has decided to proceed with cloning research without public scrutiny and deliberation, and went on to say that the presidents bioethics council does not endorse the Stanford institute, and then noted the council wanted a four-year moratorium on so-called therapeutic cloning. Oddly, the council never recommended a moratorium (which Brownback has recently been calling for and which stem-cell researchers across the board consider a terrible idea), and Kass issued his statement without bothering to consult the rest of the council.
Not that any of this behavior is all that surprising. This is just a little lying in the face of a bigger war -- a war that is far from over. The cloning debate rages on at all levels of government, refueled by the recent Raelian announcement that they had created the worlds first human clone. Never mind that, just prior to that announcement, the Bush administration blocked a worldwide U.N. ban on reproductive cloning that might have stopped the Raelians in their supposed work. The ban was vetoed because it did not also include therapeutic cloning and was insufficient for the religious right.
So the opposition continues twisting terminology. Scientists like Larry Goldstein and the folks sitting around Weissmans dinner table are painted as cold-blooded and immoral. The government is actively clouding the issues, and the media has done little to engender understanding. Meanwhile, a middle-of-the-road estimate of how many Americans will die from diseases that stem-cell research might soon cure is 130 million.
Back at the stove, Weissman pokes and prods and eventually nods his head sagaciously: That goose is cooked.
