The Missing Link in the Public Policies on Human Embryo Research
Early embryos are proving
to be valuable subjects of genetic engineering research in recent years. Stem
cells extracted from these embryos are said to be the best and perhaps hold
the key to providing several therapies to millions of people afflicted with
lethal and dreaded diseases. Yet, because the research has a tendency to endanger
or destroy the fragile embryonic life, establishing public policies to guide
such research has been difficult and controversial.
Since 1996, the appropriation
bills of the Department of Health and Human Services have banned federal funding
of research in which embryos are destroyed, discarded or knowingly subjected
to risk or injury. Yet, on August 23, 2000, the National Institute of Health
released its guidelines permitting scientists using public grants to research
on human embryonic stem cells (ESC) derived without federal funds. The guidelines
required the stem cells to be derived from excess embryos that were originally
created in the course of infertility treatment, derived with informed consent
of donors, and without any financial inducements to the donors.1
On August 9, 2001, President George W. Bush, in a televised speech, announced
new guidelines for ESC research, limiting federal funding for ESC research.
Under the guidelines, ESC must be derived with informed consent of donors, from
excess embryos created solely for reproductive purposes, without any financial
inducements to the donors, and must have been created prior to the time of
the announcement. Approximately 64 cell lines potentially meet such criteria.
Some members of the Congress are proposing introducing legislation to expand
ESC research, despite the President’s veto threat.
These guidelines, of
course, received mixed reactions from proponents and opponents of ESC research
hailing or denouncing the guidelines. The approval or disapproval of embryo
research is usually influenced by one’s view of the status of the embryo because
what we think of the human embryo determines what we may do to it, especially
in terms of research. These guidelines and legislation often attempt to find
a quick solution to the immediate concern rather than address the root of the
controversies associated with the issue, i.e., determining the status of early
embryos and what kind of protection they are entitled. This varied approach
to issues arising from scientific research involving early embryos could result
in inconsistent policies. As a result, there is a need for a coordinated approach
to issues involving human embryo research.
Principles
The relevant principles
applicable to the discussion are the principles of the sanctity of life and
beneficence. There is an apparent conflict between these two principles when
used in the context of human embryo research. Opponents of non-therapeutic
embryo research apply the principle of the sanctity of life to fortify their
position while proponents of non-therapeutic embryo research rely on a burden/benefit
analysis of the principle of beneficence.
The primary concern
about non-therapeutic embryo research, such as ESC research, is that the research
in most cases involves the destruction of the embryos. The principle of sanctity
of life underlies the concern expressed by opponents of non-therapeutic embryo
research. They resist the manipulation and destruction of what might be a human
person because for them, there is no justification to engage in research that
destroys human life. Opponents further contend that the medical benefits, which
might accrue for some patients from non-therapeutic research such as ESC research,
do not outweigh the grave consequences for the embryo, which is killed in order
to procure stem cells for medical therapy. They argue that an early embryo
is a human being because it contains a complete genome and all that is needed
to develop into an adult human being.2 Thus, opponents contend we
must not end one human life in an attempt to benefit another because it is absolutely
forbidden to directly destroy an innocent human life in order to help another.3
On the other hand, proponents
of ESC research relying on burden/benefit ratio focus on the potential benefits
of the research. They argue that the research will yield therapies that will
ease the suffering of millions inflicted with debilitating diseases such as
Alzheimer’s, Parkinson’s, heart failure, liver failure, cancer, and diabetes.
Proponents tend to minimize the destruction of the embryos and usually argue
that the potential therapeutic benefits far outweigh the harm to the embryo.
They argue that it is justifiable to modify or destroy certain human embryos
in the pursuit of cures for dreaded and lethal diseases.4
Discussion
The differences
in the debate regarding non-therapeutic embryo research usually boils down to
the differences in the respective parties’ views on the moral status of the
embryo. The moral status of an embryo continues to be an enigma in moral, legal,
and policy discussions. Views on the moral status vary, ranging from one end
of a spectrum to the other. Some view early embryos as mere tissues or cellular
material, which demands little, if anything, of us morally.5
Some view
the embryo as a living being with potential to develop into a full human being,
and as such, deserve the same moral status as a human being. The Roman Catholic
Church is among those who adopt a protective stance towards embryos. In Donum
Vitae of 1987, the Catholic Church asserted that the embryo must be treated
with the respect due a person from the very instant of his or her existence.
Thus, no objective can justify non-therapeutic experimentation on living human
embryos or fetuses, whether viable or not, either inside or outside the mother’s
womb.6 Also, in Evangelium Vitae of 1995, Pope John Paul
II addressed the status of early embryos and essentially affirmed the teachings
of Donum Vitae.7 The Catholic Church’s view is grounded in
its moral teaching which views human life as a continuum. The Church views
all human beings from conception onwards as being made in the image and likeness
of God and as meriting the same respect for their fundamental right to life.
However, some
scholars view early embryos as neither mere tissues entitled to no protection
nor persons entitled to full moral protection. These scholars usually agree
that an early embryo is a form of human life that deserves a respect commensurate
with its progressive development. Proponents of this view base their argument
on physiological evidence and philosophical reasoning. They argue that early
embryos are not to be treated with respect due a person because at such an early
stage in the development of the embryo, such life is not genuinely individuated
in the morally required sense. For them, the early embryo though human, living,
and genetically unique, is really not yet an individual in the sense in which
persons are necessarily individuals. They note that these early embryos could
split and/or recombine until individuation. Individuation is typically claimed
to occur about fourteen days following fertilization or conception with the
appearance on the embryo of the primitive streak, which indicates a decisive
moment of cellular differentiation or restriction. Thus, while acknowledging
that these early creatures deserve some moral protection, they would not accord
them full moral protection prior to their individuation.8
There is a high degree
of polarization in the debate regarding the status of early embryos. The majority
of the participants in the debate agree that early embryos have intrinsic worth
and are not just mere tissues. An early embryo is a form of human life at the
initial stage of human development. As such, the fragile embryonic life needs
to be protected. However, the disagreement stems from the amount of protection
that is due to the embryos.
The debate rages on
regarding the status of the embryo. The debate permeates the entire spectrum
of society and recently ESC research has catapulted the issue, via the media,
to the larger community. Thus, the issue of the status of the embryo is not
just an important issue in medical ethics, but it is also an important issue
to society as a whole. It is an important question in ethics, law and politics
that has significant practical implications, not only for non-therapeutic embryo
research, but also for other issues regarding the embryos such as the disposition
of excess frozen embryos from in vitro fertilization and cloning of human embryos.
Unfortunately, the different views on the status of the embryo continue to divide
participants in the debates and the gap does not appear to be closing. The
lack of consensus invariably impacts the ability to enunciate public policies
dealing with human embryos.
As the debate goes on,
there is a need to have a coordinated public policy approach, perhaps by enacting
comprehensive legislation that will address both present and future issues regarding
human embryos. There is a need to establish a broad based public panel to examine
the social, ethical and legal implications of recent and potential developments
regarding human embryo research. The panel would be charged to provide a broad
and flexible regulatory framework using general propositions and terms, which
allow for current and future issues to be addressed as they arise. A comprehensive
national legislation would help curtail court battles, inconsistent executive
guidelines, and ad hoc legislation, which leave the society in disarray.
Congressional legislation
influenced by the panel’s careful report is preferable to executive guidelines
or court decisions in this instance. Executive guidelines most likely will
be dependent on whoever is in charge of the executive branch of the government
and this could potentially lead to inconsistencies. Furthermore, the courts
are not well equipped to deal with the issue concerning embryos. Human embryos
do not enjoy the constitutional rights of a person. Roe v. Wade, decided
on the ground of a woman’s right to terminate an unwanted pregnancy as an exercise
of her right of privacy, would not be helpful because the embryos in question
are ex utero. Procreative autonomy, which includes the rights to procreate
or not to procreate, does not fully help in addressing all the issues involved.
The issues involved are vast and significant. Courts’ decisions are likely
to be limited to the issue(s) before them because courts in the United States
do not issue advisory opinions. Therefore, neither court decisions nor executive
guidelines seem to be the adequate forum for resolving the issues.
Conclusion
The United
States, unlike England and Australia, lacks a uniform approach to dealing with
issues concerning early embryos. Issues such as ESC research, cloning of human
embryos and disposition of frozen embryo continues to divide the nation. These
issues are being addressed by the three branches of the government without an
underlying comprehensive framework. As the nation’s health focus shifts away
from issues such as healthcare reform, cloning and stem cells, to national security
and bioterrorism, Congress may take the opportunity to set a panel to provide
a comprehensive framework which will influence legislation dealing with human
embryo research and related issues such as the disposition of excess frozen
embryos from in vitro fertilization and the cloning of human embryo. Congressional
legislation providing a comprehensive framework will definitely provide the
missing link to the public policies dealing with issues concerning human embryos.

- Should the moral status of the embryo impact the debate on human embryo research? If so, how should we resolve the debate on the moral status of the embryo?
- What are the ethical and policy implications of ESC research and human embryo cloning?
- Should benefit/burden ratio be employed in discussions regarding human embryo research?
