    heresa Deisher was 17 years old the first time she saw ahuman fetus. Having graduated from the Holy NamesAcademy in Seattle, Washington, in 1980, she had takena summer job in the pathology lab at the citys SwedishHospital when a friend and co-worker miscarried inher fifth month of pregnancy. The fetus arrived fixed informalin, and Deisher helped to section it to determinethe cause of the miscarriage. The body hardly seemed

    to be the remains of a sentient, soul-bearing human, asthe faith of her upbringing had taught, recalls Deisher.Instead, It looked like a space alien, she says. I called it the thingfor so many years.

    Thirty years later, Deisher sees the unborn in a different light. Shehas reversed her views on embryos and become one of two plaintiffs ina lawsuit filed in 2009, seeking to stop the US government from fund-ing human-embryonic-stem-cell research. The courts hearing the casecould issue a decision at any time; many, including Deisher, expect thatthe matter will end up before the US Supreme Court.

    Deishers co-plaintiff, James Sherley, an adult-stem-cell scientist atthe Boston Biomedical Research Institute in Watertown, Massachu-setts, is well known as a provocateur. In 2007, he went on a hungerstrike to protest against a decision by the Massachusetts Institute of

    Technology (MIT) in Cambridge to deny him tenure, which he attrib-uted to racism.Deisher is less well known. A cellular physiologist educated at Stan-

    ford University in Palo Alto, California, she spent 17 years in the biotechindustry at companies including Genen-tech, Immunex and Amgen. Three yearsago, she founded a tiny, privately heldSeattle firm called AVM Biotechnology the name is a loose abbreviation for AveMaria which is dedicated to hasteningadult-stem-cell therapies to the market,and to developing alternatives to vaccinesand therapeutics made using cell lines from aborted fetuses. She has alsolaunched a non-profit group, the Sound Choice Pharmaceutical Institute,which among other things is investigating, as she puts it, the potentiallink between human DNA in childhood vaccines and autism.

    Deisher, who is 48 and goes by the name Tracy, is smart, driven andcommitted. A devout Catholic and a divorced mother of two boys aged9 and 12, she rises as early as 3:45 a.m. to ride an exercise bike whilepraying the rosary. She is casual and unpretentious, with a dry humourand a can-do attitude: she spent New Years Eve laying carpet in the180-square-metre office space that her company recently moved into.

    She is also a bundle of contradictions: an adamant right-to-lifer,whose closest, long-standing friends are pro-choice liberals. She madea healthy six-figure salary at the cream of US biotech companies, butthought nothing of mortgaging it all to launch a no-name firm as theeconomy slid into a recession. She is a no-frills dresser who has worna simple gold cross virtually every day for the past 18 years. But sheflaunts her intellect. In the past, she alienated friends with a formidable

    vocabulary fed by a dictionary-reading habit. And she says that thoseat her church who disagree with her stem-cell views oftentimes needsome education.

    Above all, Deisher is supremely confident in her positions, includingher attempt to prevent hundreds of millions of dollars from going tohuman-embryonic-stem-cell research. Its very difficult to get passion-ately, morally protective of what physically truly is a clump of cells, shesays. But that is a human being. Scientifically, you cant debate that.

    Her arguments, now part of a national discussion, can be hyperbolic.And she does not shy away from assigning motivations to her ideologi-cal foes. She says, for example, that embryonic-stem-cell scientists aremostly attracted to the cells convenience their rapid growth andwhat she calls the ease of working with them in the lab. Their science,she says, is not about helping patients and its not about advancing

    the common good.

    I wish that Tracy werent so polarizing, says Chuck Murry, co-director of the Institute for Stem Cell and Regenerative Medicine atthe University of Washington in Seattle, who has known Deisher sincethey were postdocs together at the university in the early 1990s. Sheskind of the Sarah Palin of stem cells. It would be so much easier tohave more rational discourse rather than somebody who heats up the

    vitriol like this. Deisher counters that she sticks to scientific arguments:My approach to the stem-cell issue is to remove the polarizing moral

    debates and speak and educate only about the science.

    Regaining the faith

    Deisher showed a bent for science early, teaching herself calculus to wina state competition in which high-school students had to plot the orbitof Mars and design a spaceship and flight path to get there. Tracy wasalways very much a leader, an independent thinker, says Liz Swift, whotaught Deisher physics at Holy Names and is now the schools principal.In those days, a fun Friday night for Deisher meant several hours at theUniversity of Washingtons astrophysics laboratory, followed at 10 p.m.by an outing with girlfriends only after her mother had checked herfor make-up and low necklines.

    As a girl, Deisher was torn between her mothers conviction that

    life began at conception and the views of her two outspoken aunts,both staunch supporters of Planned Parenthood, who reminded herregularly: Its not a baby. Its a clump of cells. Deishers experienceas a teenager in the Swedish Hospital pathology lab left her with-

    out any doubts as to who was right. Iwalked out of that lab that weekend andI threw my faith in the garbage can, sherecalls.

    Weeks after her experience with thefetus, Deisher began undergraduate stud-ies at Stanford, where she went on to earnher PhD in molecular and cellular physi-

    ology. On the side, she worked at Genentech in South San Francisco,California, developing assays to support the companys anti-plateletagents. I was very left-wing, she says. I was in science, and sciencewas much more interesting than religion. I encouraged a couple offriends to have abortions, urging them to trust her first-hand experi-ence with a fetus in formalin.

    Several years later, during an anatomy lab, she encountered thecadaver of a woman also embedded in formalin looking, she says,not so very different from the thing. It suddenly struck her that thefetuss alien looks may have simply been attributable to the preserva-tion process. That opened up what she calls a long, slow process ofcoming back to the faith of her childhood. It was one of three pivotalexperiences that she talks about as having influenced her decision toactively fight against embryonic-stem-cell research.

    After completing a postdoctoral fellowship at the University of Wash-ington in 1993, Deisher went to work for the biotech company Repligenin Waltham, Massachusetts, working on monoclonal-antibody thera-

    peutics. After watching three rounds of lay-offs, Deisher decamped toa Seattle company called Zymogenetics, where she became involved ina cardiovascular-biology group.

    Soon after she arrived at the firm in 1995, Deisher isolated whatseemed to be pluripotent stem cells from adult cardiac muscle. Theydifferentiated, she says, into cell types including heart muscle, skeletaland smooth muscle, connective tissue, skin, bone and cartilage. Peo-ple would come into the lab and they would practically start to drool,Deisher recalls. It was mind-boggling what these cells became. InMarch 1998 8 months before the first report that human embryonicstem cells had been isolated the company filed a patent applicationon the cells, with Deisher listed as first inventor.

    It was, and still is, a controversial claim. Kenneth Chien, an expertin studies of heart progenitor cells at the Department of Stem Cell

    and Regenerative Biology at Harvard University in Cambridge,

    Massachusetts, says that nobody has been able to identify a truly

    pluripotent stem cell from any adult mammalian heart.Many of her colleagues at Zymogenetics reacted with ferocioushostility, Deisher says. She recalls one scientist who cornered her, spit-tle flying from her mouth, shouting: Adult stem cells do not exist out-side the haematopoietic system! Who the blank do you think you are,God? Deisher was ordered, she says, to stop working on the cells.

    The company abandoned the patent application in 2004, but Deisherremains unapologetic about her claims. The website for AVM pro-claims: Dr. Deisher was the first person world-wide to identify andpatent stem cells from the adult heart. Her discovery remains one of themost significant discoveries in the area of stem cell research. And thevehemence with which colleagues resisted made me open my eyes,Deisher says, to the very real and, she says, unscientific passionsthat can infect defenders of scientific orthodoxy. Science, she reasoned,was not so objective after all.

    It was a second formative experience for her. Deisher had returnedto religion, tentatively, in the early 1990s. Now, her disillusionmentwith colleagues at Zymogenetics led me back deeply and profoundly,she says. She left the company for Immunex which was acquired byAmgen in 2002. Human embryonic stem cells were back in the news, aspresident George W. Bush defined a policy that allowed federal fundingfor research on a score of existing cell lines. For Deisher, it was a scoretoo many. I was extremely disappointed, she says. She felt the policyencouraged an unmerited hype around embryonic cells that deprivedadult-stem-cell therapies of support.

    Through a friend of her parents, Deisher came into contact withSharon Quick, a local doctor and conservative activist, who invited herin 2006 to speak on a televised panel about stem-cell research. Murryhad also been invited to speak. He recalls Deisher reading prepared

    remarks about human-embryonic-stem-cell research. There was alot of misinformation in there. Her talk, he says, didnt educate andfocus. It obfuscated and frightened.

    In response to Murrys criticism, Deisher sent Nature a copy of thetalk. It argues that human embryonic stem cells could provoke animmune response and form teratomas (tumours containing varioustypes of cell); claims that safe, clinically proven alternatives exist; andcategorically dismisses any potential promise embryonic cells mayoffer: There is no commercial, clinical or research utility in workingwith human embryonic stem cells. The event put Deisher on the mapfor anti-embryonic-stem-cell activists. It also led her to a third trans-formative moment in her advocacy.

    In early 2007, Deisher was invited to speak to a group of Republicanstate lawmakers in Olympia, Washington. One of the other speakers

    was a mother who had adopted a frozen embryo from a fertility clinic.

    The resulting child, a girl then four years old, stood beside her.

    Deisher was transfixed. It was, she says, the turning point to becomeless scientific about it, and actually feel emotion, and a stronger senseof commitment.

    It was this commitment that led Deisher to found AVM in Febru-ary 2008. The companys mission, in part, is to eliminate the need forembryonic-stem-cell therapies and enable adult-stem-cell companiesto succeed by developing, for instance, drugs that promote stem-cellretention in target organs. It is also working on alternatives to vaccinescurrently produced using cell lines derived from fetuses that had beenaborted decades ago. AVM has five members of staff, all of whom areunpaid, and occupies three rooms in a former nurses dormitory.

    She financed AVM with her retirement savings, and with proceedsfrom the sale of her house. In 2009, an equity offering raised an additional$225,000 from angel investors. Deishers non-profit group, the SoundChoice Pharmaceutical Institute, is housed in the same premises and isstaffed by four people. Last year, the institute won a $500,500 two-yeargrant from the MJ Murdock Charitable Trust, based in Vancouver, Wash-ington, to study whether residual human DNA in the measles, mumpsand rubella (MMR) vaccine might trigger autism. Stanley Plotkin, emeri-tus professor at the Wistar Institute in Philadelphia, Pennsylvania, andinventor of the rubella vaccine, calls the idea off the wall. The wholeidea, in my view, is just pernicious and just raises a spectre which has beenredundantly disproven. John Van Zytveld, a senior fellow at the Murdocktrust, who oversees its science grants, says that Deishers proposal cameback with a strong [peer] review and so we opted to support it.

    a call to aRms

    In the spring of 2009, Deisher got a call from Sam Casey, a lawyerthen based in Fairfax, Virginia, who was representing Do No Harm, a

    coalition opposed to human-embryonic-stem-cell research. The USNational Institutes of Health (NIH) in Bethesda, Maryland, had justissued draft guidelines proposing to open up funding for the research,complying with an executive order from President Barack Obama.Casey enlisted Deisher to help write the groups response.

    He also told her that he was laying plans for a lawsuit if the final guide-lines remained substantially unchanged from the draft. The suit wouldassert that the guidelines contravened an existing law, the DickeyWicker amendment, which prohibits federal funding of research in

    which human embryos are destroyed.The NIH published its final guidelines on

    6 July 2009, allowing financial support for workon human embryonic stem cells derived ethicallyfrom leftover embryos at fertility clinics, but not

    for work that went into their derivation. I was

    very disappointed, Deisher says. I had hoped and thought that they

    would listen.Soon afterwards, Casey, now with the Jubilee Campaign in Washing-ton DC, called Deisher. He told her that the lawsuit was going ahead,and asked her to be one of the plaintiffs. She spent several weeks pon-dering her decision. There are huge ramifications to being involvedin a lawsuit, she says. It is frightening to speak out. I dont care for thenotoriety. Deisher was also keenly aware that James Sherley had signedon as a plaintiff. She had never met him, but she had followed his widelypublicized tenure dispute with MIT. She worried about how a publicassociation with him would affect her reputation.

    She made it clear to Casey that if he wanted her as a plaintiff, ahigh-profile, Sherleyesque approach was out of bounds. No theat-rics, no histrionics, no hunger strikes, she says. It was agreed, andDeisher joined the suit. Her co-plaintiffsincluded embryos; an embryo adoptionagency called Nightlife Christian Adop-tions; the Christian Medical and DentalAssociation based in Bristol, Tennes-see; and individuals wishing to adoptembryos.

    The lawsuit, filed in August 2009, wasbarely noted by the press. And when, inOctober that year, District of ColumbiaDistrict Court Judge Royce Lamberth ruled that none of the plaintiffshad standing to sue, Deisher received the news with a measure of relief.She could return to her preferred focus: her children and her work.

    But in June 2010, the US Court of Appeals for the District of Colum-bia Circuit ruled that Deisher and Sherley alone should be grantedstanding to sue, because, as adult-stem-cell researchers, they were

    in danger of imminent injury. The court reasoned that by allowingfederal funding of embryonic-stem-cell research the NIH increasedcompetition for its limited funds, making it harder for adult-stem-cellresearchers to win grants. The appeals court then sent the case back toLamberth. Deisher was concerned. Its a little unnerving to know thatyou are the only two with standing.

    Unlike Sherley, Deisher has never applied for an NIH grant assome opponents are quick to point out. She contends that she is stillhurt by the guidelines, just as, by her reasoning, all adult-stem-cellresearchers are hurt by the NIHs deliberate focus on embryonic stemcells. Moreover, she says, I would like to, I intend to and I plan toapply for NIH grants.

    It is hard to argue that adult-stem-cell researchers are at a disadvan-tage, however. Numbers provided by the NIH show that since 2002,

    when it first funded a human-embryonic-stem-cell grant, the agency

    has spent more than four times as much $2.3 billion on researchwith non-embryonic human stem cells. Nor has the money for non-embryonic work dwindled as embryonic funding has grown; in 2003,the NIH spent $191 million on adult-stem-cell research in humans; lastyear, it spent $388 million.

    Deisher responds that the United States lags in clinically testing newtherapeutic uses for adult-stem-cells, instead focusing on well estab-lished indications such as leukaemia and lymphoma. Thirty-nine per-

    cent of adult-stem-cell trials for unconventional indications registeredwith clinicaltrials.gov take place in the United States, compared with71% of trials for conventional uses. Defenders of the NIH say thatlax regulatory and safety hurdles in some countries may explain thediscrepancy. Sean Morrison, director of the Center for Stem Cell Biol-ogy at the University of Michigan in Ann Arbor, works on adult andembryonic stem cells, and says that the idea that the NIH is biasedagainst adult-stem-cell research is ridiculous.

    the hammeR dRops

    On 23 August 2010, Lamberth issued a preliminary injunction sid-ing with the plaintiffs. That immediately shut down federally fundedhuman embryonic experiments, leaving the research community reel-ing and angry. Deishers phone began ringing off the hook, with queries

    from reporters around the world. The next day, walking into her officein a building that shares space with other research groups, she wasprepared for dirty looks. But if I got them, I didnt notice. The responsewas overwhelmingly positive.

    Deisher made a hastily arranged trip to Washington DC the nextweek. There, she met Sherley for the first time, during an hours-longstrategy session at the offices of Gibson, Dunn and Crutcher, the DClaw firm arguing the case. I asked lots of questions, Deisher says.(Sherley is a very nice man, she adds. Hes a good scientist.)

    It would be 17 days from the preliminary injunction before a stayfrom the appeals court allowed embryonic-stem-cell research to resume.Since then, the lawsuit has been proceeding on two tracks. At the lower,district court, Judge Lamberth is considering both sides requests for a

    speedy, summary judgement on whetherthe NIHs guidelines are legal. The highercourt, the Court of Appeals for the Dis-trict of Columbia Circuit, which residesone level below the Supreme Court, isconsidering whether Lamberth met thelegal standard for granting the prelimi-nary injunction. Either court could ruleat any time, and no matter what the deci-sions, appeals are expected (see Stem cells

    in court). The case has taken emotional energy, Deisher says, but nota great deal of her time. She has not hung on every one of its twists andturns. In many ways, her life goes on unchanged.

    Old friends, for example, remain old friends. Two former high-school classmates who recently visited Deisher at her office both ada-mantly oppose her position on the research, but greet her with evident

    warmth. I can say wholeheartedly that I am envious of her passion,says one. But later, she e-mailed to ask that her name be withheld fromthis article. I cannot afford to have a search engine associate me withan individual whose actions are in such opposition to the beliefs of mypersonal and professional community, she wrote.

    The biggest lesson Deisher has learned from the lawsuit, she says,is how many scientists are against [human-embryonic-stem-cellresearch]. I did not know that. I did not expect the level of support andencouragement that I have received. The extent of that support maybe tested if the Court of Appeals for the District of Columbia Circuit,when it rules on the issue, agrees with Deisher. If it does, it will shutdown hundreds of human-embryonic-stem-cell experiments oncemore possibly for good.
