Critique of Stem Cell Research

The other day there was an article published on the Episcopal News Service website regarding Stem Cells and Stem Cell Research. I shared it with Dr. D. Joy Riley, a physician, former medical researcher, and bioethicist. Joy is an increasingly important voice among orthodox Christians dealing with this issue. I asked her if she would comment on the article.

What follows is first the ENS piece and then Joy Riley's responses. I think you will find them interesting.

While the debate over the many ethical implications of stem cell research rages, studies in molecular genetics, genomics and cell development continue to yield new information. One of the learnings which may be surprising to many is that the differentiation of a stem cell depends on the environment or microniche where it resides.

"What a cell's neighbors 'say' to it chemically, and what it says to its neighbors, impact what kind of cell it becomes," reported Dr. Christie A. Holland, retired Professor and Chair of Virology, Immunology and Infectious Diseases at the Children's Medical Center in Washington, D.C.

"If context matters in ethics as well as in the development of a cell," posed Karen LeBacqz, bioethicist in residence at Yale, "we need to realize that we are talking about a different context here. It is a great pity that the debate around stem cells got framed in terms of the abortion debate. They are very different contexts."

Holland and Lebacqz were addressing the Ecumenical Roundtable on Science, Technology and the Church, as part of the program, "Embryonic Stem Cell Research: Churches, Ethics, and Politicians" presented by members from the United Church of Christ. This year's Roundtable was hosted April 27-30 by the Executive Council Committee on Science, Technology and Faith at the Emrich Retreat and Conference Center in the Diocese of Michigan.

Ron Cole-Turner, H. Parker Sharp Professor of Theology and Ethics at Pittsburgh Theological Seminary, led off the panel with a review of the history of the debate surrounding stem cells, and with the hope that the panel would serve as a resource for those at the meeting who may be called upon to speak to the issues in the political arena.

Olivia Masih White, who teaches biology at John Carroll University in Cleveland, reviewed the basic biology of stem cells, clarifying terms and adding "What I taught 20 years ago is completely different than what I teach my biology students now, and the best contemporary science is still changing."

Sandra Michael, convener of the Episcopal Network on Science, Technology and Faith, commented that she was glad White made the distinction between the two types of stem cells, totipottent and pluripotent. "This is rarely clarified in popular presentations on stem cells and is critical for understanding how they work."

Michael's research as Distinguished Service Professor at the State University of New York at Binghamton is in the genetics, endrocrinology and immunology of reproduction. "Just as people who aren't specialists in these topics need clear and thorough scientific explanations, scientists and clinicians need to consider the issues in a religious context as they apply the knowledge gleaned from their research."

The interplay of science, ethics and theology in the panel enabled the 40 Roundtable participants -- Lutherans, Presbyterians and Methodists as well as the UCC team and Episcopal hosts -- to clarify the other scientific terms which are used confusingly in politics and the popular media, as well as to explore the implications of stem cell research and therapies.

Lebacqz raised the question of just access to therapies developed from stem cell research, since the stem cell lines approved by the current administration for federal funding are not diverse enough to meet the needs of different ancestral groups. The ethics around the acquisition of eggs and somatic cells for research are exceedingly complex, and also generated discussion.

Stem cell therapies hold the promise of both increasing longevity and of improving the quality of longer lives, giving rise to another cluster of questions. Interestingly, the Working Group on Faith and Genetics in the Diocese of Massachusetts, also ecumenical in makeup and represented by several members of the Roundtable, has announced that the science of human aging and efforts to slow it will be the group's next topic for study.

Lebacqz conlcluded the formal presentaion with a series of her own theological questions. "What," she pondered, "Does being 'made in the image of God' mean in our time? For me, our dignity is relational; it has to do with communication, with being in communion with others and God." She concluded by returning to the science. As we understand more about how cells communicate and provide a context for one another, we see the resonance between science and theology deepen.


FROM DR. D. JOY RILEY

This is a proactive group; they are ecumenical in scope, but I am not sure there
is a diversity of opinion RE stem cell research. That is unclear. I mostly
take issue with such comments as these:

1) "If context matters in ethics as well as in the development of a cell,"
posed Karen LeBacqz, bioethicist in residence at Yale, "we need to realize that
we are talking about a different context here. It is a great pity that the
debate around stem cells got framed in terms of the abortion debate. They are
very different contexts."

Embryonic stem cells have, by definition, embryos as their source; in harvesting embryonic stem cells, embryos are destroyed. That is precisely what the abortion AND the ESC debates are about: embryos are human. These vulnerable humans are destroyed in both instances, with the latter utilizing them effectively for parts. Whether a calf is killed on the roadway, or cut up with a butcher’s knife for veal parmesan, the calf is still dead. The differing “context” is that of the garbage heap or the diner’s plate.

2) "Ron Cole-Turner, H. Parker Sharp Professor of Theology and Ethics at
Pittsburgh Theological Seminary, led off the panel with a review of the history
of the debate surrounding stem cells, and with the hope that the panel would
serve as a resource for those at the meeting who may be called upon to speak to
the issues in the political arena."

Cole-Turner advocates being a resource for the political arena, although he does not say on which side. The book he edited on human cloning (Human Cloning: Religious Responses, Westminster John Knox Press, 1997) however, does support research up to fourteen days after fertilization or zygote formation, on what he terms “pre-embryos.” It should be noted that this is a term usually employed for semantic purposes; it is not a scientific term.

3) "Lebacqz raised the question of just access to therapies developed from stem
cell research, since the stem cell lines approved by the current administration
for federal funding are not diverse enough to meet the needs of different
ancestral groups. The ethics around the acquisition of eggs and somatic cells
for research are exceedingly complex, and also generated discussion."

The question of justice is a valid one, but I think this is a back door approach. The argument here is one for ESC (embryonic stem cell) research. What the embryonic stem cell research lobby wants is tax dollars in order to do research that is at least controversial. I think the real question here about justice, is, should those who understand this destruction of nascent human life for what it is have to pay for something they consider morally reprehensible? As there are no therapies to date from embryonic stem cells, the question of justice between ancestral people groups rings rather hollow at this time.

The acquisition of eggs is ethically very questionable; on this we agree. The number of human eggs required for therapeutic cloning research would be astronomical. From whence would these come? Egg procurement requires females of reproductive age, but over 21 years, in order to give consent (at least in the United States), for a procedure that entails a number of risks. In South Korea, two egg “donors” from the Hwang Woo-Suk debacle have filed suit for not being duly informed of the risks.

The acquisition of somatic cells is not typically problematic, ethically or physically, unless one has a problem with his/her cheek (mouth) being swabbed with a Q-Tip! The inclusion of somatic cells as ethically complex is somewhat spurious.

4) “Lebacqz concluded the formal presentation with a series of her own
theological questions. ‘What,’ she pondered, ‘Does being made in the image of
God mean in our time? For me, our dignity is relational; it has to do with
communication, with being in communion with others and God.’ She concluded by
returning to the science. ‘As we understand more about how cells communicate and
provide a context for one another, we see the resonance between science and
theology deepen.’”

Does this mean that only those who can communicate with others are human? How far
does this argument extend? Embryos cannot relate, so they are not made in
the image of God? What about those whose disease states render them incommunicado with others? Are they "no longer made in the image of God" or "never were in the image of God?" What about their eschatological potential for being in communion with God and others? What if they "speak" a language of angels, and not of men, so we are the ones without understanding?

These are a few of my thoughts. . .
