THE EXORBITANT PRICE
OF EMBRYONIC STEM CELL RESEARCH
A
Pastoral Letter from the Catholic Bishops of Kansas
March 16, 2007
INTRODUCTION.
In 2006, voters in Missouri approved an amendment to their
state constitution prohibiting the legislature from regulating or
limiting research in which human embryos are created and destroyed
to provide stem cells for research. This amendment disregards the
most fundamental human right of those who are most defenseless –
their right to life.
Shortly after the results of the Missouri vote were announced,
Governor Sebelius publicly referred to the new amendment as “a step
forward to at least ensure in Missouri that research can continue.”
She went on to say that she thinks “there is a lot of interest in
looking at that kind of language here in Kansas.”
Concerned at such a prospect, we want to offer Catholics and all
people of good will in Kansas the following explanation of the
issues at stake in human cloning and embryonic stem cell research.
It may provide some clarity amidst the confusion.
WHAT IS A STEM CELL?
Stem cells are primitive human cells that, when they divide, can
form a variety of more specialized cells. For example,
just one type of stem cell in our bone marrow works to replace all
the different types of blood cells (white, red, etc.) when we need
them.
ADULT STEM CELL RESEARCH.
Human stem cells hold great promise for the development of therapies
to regenerate damaged organs, and to heal people who are suffering
from terrible diseases. Most scientific research uses cells obtained
from adult tissue, blood from the umbilical cord, and other sources
that pose no moral problems. Versatile stem cells have been found in
bone marrow, blood, muscle, fat, nerves, amniotic fluid, and even
the pulp of baby teeth. Many successful therapies have been
developed using these adult stem cells.
We Catholics applaud the
vast array of scientific research that is conducted ethically and
that respects the dignity of the human person. We strongly support
stem cell research using adult and umbilical cord stem cells.
EMBRYONIC STEM CELL
RESEARCH.
Some scientists, however, are interested in doing research using
stem cells obtained by killing human embryos when they are about one
week old. These embryos are obtained from one of two sources.
IN VITRO
FERTILIZATION.
Embryonic stem cell research commonly involves harvesting cells from
human embryos created in a laboratory by “in vitro” fertilization.
The embryos created are frozen and stored for future use. For
various reasons, not all the embryos are used. Some people consider
these “leftover” embryos as a potential resource for scientific
research. This is a morally unacceptable process on many grounds,
and the cell harvesting process itself destroys the living embryo.
HUMAN CLONING.
Embryonic stem cells might also be harvested from embryos created by
cloning, also known as “somatic cell nuclear transfer” (the same
process used to create Dolly the sheep). In human cloning, the
nucleus from an adult donor cell is inserted into a donated egg cell
from which the nucleus has been removed. The inserted nucleus
provides the necessary DNA for the new cell to function and divide.
The resulting human embryo is allowed to grow for several days, then
destroyed to obtain stem cells for experimentation.
Some would distinguish between “therapeutic”
cloning and “reproductive” cloning, but the process is the same in
both cases. The only difference is what is done with the new embryo
created by the cloning process: implant it in a woman’s womb to
attempt a live birth; or destroy it to harvest its stem cells. Thus
far, however, despite many years of experimentation by scientists
all over the world, all attempts to use human cloning for either
“so-called”
therapeutic or reproductive purposes have
failed.
SERIOUS MORAL PROBLEMS: DESTRUCTION OF
HUMAN LIFE.
Some hold there is no moral problem with harvesting cells from
embryos because they claim that the embryo only holds the potential
for human life
and is not actually human. But the human
embryo is not something other than human;
human stem cells can
only be
harvested from a human being. It is just that this human being was
killed instead of allowing it to develop normally. Regardless of
whether the human embryo is obtained from “in vitro” fertilization
or human cloning, human life is
destroyed for the sake of scientific
research, in the search for (as yet purely hypothetical) medical
therapies. This is a crime against life.
It is never morally permissible to destroy one
human life, even if it is done in the hope of benefiting other human
beings. Laws intended to sanction embryonic stem cell research are
immoral because they give legal protection to the violation of the
most fundamental of all human rights.
SERIOUS
MORAL PROBLEMS: PRAGMATISM.
Embryonic stem cell research focuses on the advance of science and
the potential of curing diseases, but to the detriment of human life
and dignity. Some even say this is a small price to pay for the
economic development of Kansas: if we
do not permit and promote embryonic stem cell research, they say, we
stand to lose the economic benefits promised by the biotechnology
industry (a similar argument was used by proponents of slavery, who
said that certain states could not survive economically without this
despicable institution). Such claims are baseless, as other states
and countries that ban human cloning have taken a leadership role in
the development of biotechnology. The primary question is whether
embryonic stem cell research can be pursued without harming another
human being, and our own humanity in the process. The answer to this
question is quite clearly “no.”
Some
proponents also argue that if the frozen embryo is going to be
killed anyway, what can be wrong with using them for the benefit of
others. This line of reasoning is flawed. A death-row prisoner, a
terminally ill patient, and indeed each living person will die one
day, but that does not entitle another to kill human life at will
for the purposes of scientific experimentation. What is more, in the
case of frozen embryos, they would survive if someone had not
decided to give them over to be killed for research purposes,
instead of implanting them in their mother’s womb.
SERIOUS MORAL PROBLEMS: VICTIMIZING WOMEN. Women, too, are
victimized by the promotion of embryonic stem cell research. The
process of cloning human embryos for research requires a huge number
of female eggs. There is a certain amount of inconvenience, pain and
substantial health risk associated with the process for harvesting
eggs. For this reason, it is likely that only women driven by need
(typically the poor, including ethnic minority women, students, and
women from developing countries) would donate the eggs needed for
experimentation. Advance in research and finding cures for disease
would be achieved at the expense not only of human beings at their
earliest stage of development, but also of women in desperate
circumstances.
CONCLUSION. Each of us was once an embryo. This affirmation is
based on a clear grasp of the most basic biology, not on religious
faith. Once human life begins (which always occurs at fertilization,
or at an event that mimics fertilization, like cloning), this new
living being is a member of the human race who is worthy of respect
and protection from harm threatened by embryonic stem cell research.
The human embryo has such a claim on all of us.
As
Catholics, our opposition to embryonic stem cell research is also
confirmed and strengthened by our faith. We believe that God became
man in the womb of the Virgin Mary, going through all the stages of
prenatal human development. This religious truth elevates the
dignity of human nature above that of even the angels and sanctifies
human life from its beginning at conception to natural death. And if
that were not enough, the sacrificial death of Jesus on the cross
communicates the height and depth, the length and breadth of the
love God has for each of us. Jesus, the Son of God, gave himself up
to death, shedding his last drop of blood, because each individual
human life created by God is of incalculable worth.
How
can we value so little what God values so much?
