The Ethics of Embryonic Stem Cell Research
In a world of advancing technologies and methods, regenerative medicine is becoming a
new way of looking at medicine. Embryonic stem cell research is blooming out of these new
methods. Embryonic stem cells are self-renewing cell lines that are the basis for all the cells and
tissues in the body. These embryonic cells are pluripotent, which means they can become any
cell or tissue in the body. Even though they are embryos, they cannot develop into whole animals
or humans. The embryos are in the in cleavage stage, which means they are not differentiated
cells. The embryos have developmental plasticity. Their plasticity allows the embryo to be
separated into two halves or two whole cells to be merged together and still develop and grow
normally. It is because of their plasticity that scientist can derive stem cells from these embryos.
With the derived stem cells, scientists can culture and grow them into tissues or cells that can
replace bad or damaged cells in a patient with an incurable disease. Stem cells have the potential
to correct heart disease, diabetes, Alzheimers,Parkinsons, cystic fibrosis, stroke or spinal
injuries, etc. (Baharvand 1-10). Embryonic Stem Cell research holds great promise in therapeutic
medicine.
Pre 1975, there were moratoriums on embryonic stem cell research in the areas of study
and finance. After the 1973 Roe vs. Wade case that ruled a fetus is not a person, Congress
established a national commission, which provided guidelines for fetal research in 1974. In July
of the following year, the moratorium was lifted. Regulations stated that the research had to
provide biomedical information that cannot be obtained another way. However, the agreement in
1975 elapsed and was not renewed in 1980. When President Reagan was elected, he ended
federal funding for the research. In 1993, the moratorium on federal funding was lifted.
However, three years later a new congress was elected and again banded federal funding for this

research. In 2001, Bush granted limited funding on human fetal research not including many
areas of research (Fletcher 27-34). Currently, stem cell research is legal and funded due to the
overturning of this rule by President Obama.
Despite the legal restriction and promising potential future of stem cell research, many
people are not enthusiastic about the recent advancements. With growing advancements, there
has been growing opposition. Many opponents believe it is immoral to use potential human lives
for conduct experiments. Some of the embryos used in experiments are from aborted fetuses
(Fletcher 30-31). Critics are concerned that doing research on embryos from aborted fetuses will
encourage women to have abortions. Others question the method of freezing embryos not being
used immediately (Herold 119-120). In addition, there is debate on the possibility of cloning
being a byproduct of so much research and advancements (McCartney 90). Despite the debate
and accusations, the research is morally permissible and greatly beneficial on many grounds.
Embryonic Stem Cell research is morally permissible when it will improve a human life, when it
improves our existing methods for testing, and when it enhances our knowledge.
When considering the moral permissibility of embryonic stem cell research, one must
consider the risks and benefits of Utilitarian ethics. Embryonic stem cells in the blastocyst-stage
are undifferentiated and are used by scientists for research. When in in-vitro culture systems, the
stem cells are allowed to grow and be observed in a controlled way. In these culture systems,
scientists have been about to study human genetic disease, gene function, and developmental
biology (Baharvand 1-3). Through these studies scientist and doctors have found ways to cure
heart disease, Alzheimers disease, Parkinsons disease, cystic fibrosis, retinitis, organ failure,
and other incurable diseases (Schuklenk 30). Embryonic stem cells have the potential to fix any
medical problems involving the loss of a particular kind of stem cells. Most of these illnesses

have no other means of a cure. Embryonic stem cells hold a great potential for the future of
medicine and curing diseases. When looking at the risks or harm factor, it is minimal (Baharvand
1-10). There will always be a risk of abuse, as there is with many things in life. In this case, the
benefit will largely outweigh the risks. Therefore, embryonic stem cell research is morally
permissible by Utilitarian ethics.
Another argument for embryonic stem cell research is that scientist can do research for
new medicine on the tissues and cells made from cultured systems rather than conduct animal or
human testing. Animal and human testing can cause complications in the human or animal. In
the animals case, it can even cause death (Thomson 21-22). The method of using cultured
tissues and cells from embryonic stem cells can improve our existing methods, and in this case,
provide less harm. Since the embryos are alive but not human lives themselves, it is morally
permissible to tests on the tissues cultured from them. Additionally, since embryos are not
persons but rather potential persons, the overall harm is less, which improves and advances our
technology and methods (Thomson 15-24). Therefore, embryonic stem cell research is morally
permissible because it enhances old methods into newer more effective ones.
The pluripotency of the embryonic stem cells have allowed scientist to make tremendous
advancements in modern medicine. Adult human stem cells are limited to forming only certain
kinds of cells. The plasticity and pluripotency of the embryonic stem cells have give rise
significant gain of knowledge. Doctors and scientists have been able to make drug discoveries
and other advancements (Thomson 15-20). When conducting experiments, scientists were able to
observe how cells grow and develop. Scientists have been able to target and better understand the
enzymes that help fetuses age. Differentiation is also a major area of study. Scientists are
observing what happens in differentiation, maturation, and commitment of the cell (Baharvand 1-

10). With this gain in knowledge, they are hoping to be able to grow whole organs for
transplantation. Scientists look confidently at the future of embryonic stem cell research.
Because of all the knowledge that can be gained, embryonic stem cell research is morally
permissible. It provides us a better understanding of the human body.
Even though embryonic stem cell research has many benefits, some people disagree with
it. Most of the time embryos are obtained from aborted a fetus, which raises a lot of debate.
Critics believe that women will be more inclined to get abortions, justifying it by saying it is
going to a good cause. They believe that by using these fetuses for research that can cure
diseases women will feel that it makes the abortion okay. Critics believe that abortion is
already a very controversial subject and that encouragement to get them would corrupt our
society even more (Fletcher 29-32). Under these conditions, embryonic stem cell research is
morally impermissible.
Nevertheless, three objections make the abortion argument invalid. First, the use of the
embryos from aborted fetuses has shown no increase in abortion rates. The claim that they will
be more okay with the abortion may be true, but a woman would not get an abortion solely
because the fetus could be used in research, but rather for other reasons as well. Secondly, legal
stipulations have been in place since 1993. A doctor or scientist cannot request the permission to
use aborted fetal tissue until the procedure has taken place. In addition, there can be no payment
to the mother or alterations in the methods used to abort the fetus. Thirdly, if the scientists
working on the stem cells are to be held responsible for the womans choice in getting an
abortion then others too should be held responsible. For example, those who encourage
education of women would too be held responsible for women who choose their career over the

child (Fletcher 29-32). These three points weaken the opposing objections and strengthens the
case in favor of embryonic stem cell research.
Another worry of the opposing party is that cloning could be a byproduct of so much
research in the subject. Cloning is defined as an individual grown from a single somatic cell
nucleus of its parent that has been implanted into an egg cell from which the nucleus has been
removed; then this enucleated cell containing the implanted nucleus taken from the somatic cell
is stimulated electrically and cell division and production of a new embryo begins to take place
(McCartney 90-91). For example in February 2003, Dolly, a sheep, was cloned from a sheep
that died prematurely by this method. In terms of embryonic stem cell research, cloning is
defined as creating a genetic identical. The Advanced Cell Technologies has been able to do
human cloning and parthenogenesis (development of an egg into an embryo without fertilization)
through a few cell divisions. Critics believe that these discoveries are like playing God. People
should not try to recreate life and that it goes against the nature of life (McCartney 90-92). On
these grounds, oppositionists believe embryonic stem cell research is impermissible.
Cloning is something to be concerned about; however, in the case of embryonic stem cell
research, it should not be a concern. Advanced Cell Technologies claims that the research and
development of clones and parthenogenesis is solely for the purpose of research and study and
nothing else. The normal way of deriving stem cells from embryos destroys the outer membrane
of the blastocyst inhibiting it from becoming an entire organism; therefore making it pluripotent
rather than totipotent. The largest thing that the pluripotent can form is an organ (McCartney 90-
92). Therefore, rules and regulations can be put in place to outlaw methods that can produce
whole organisms. In addition, one must consider that everything has a risk and that abuse is
evitable. The question would be do the benefits outweigh the risks. As mentioned earlier, the

benefits do indeed outweigh the risks. Hence, cloning is not a concern and embryonic stem cell
research is still morally permissible.
Lastly, objections against the research also claim that is not morally sound to keep
embryos in large embankments kept at a temperature of minus 320 degrees. They argue that
those embryos are human lives and should be treated with the same respect as fully developed
human beings. These critics make the point that we would not keep toddlers frozen in
embankments in the thousands, so we should not keep the embryos locked up (Herold 119-
123). To these critics a life begins at conception, and therefore believes it is morally unsound to
keep embryos frozen in embankments.
Since there has been so much debate over whether it is ethical to keep the embryos
frozen in embankments, questions have been raised on what makes a human life a human life,
and at what stage is it considered a human life. Many people are confused on the difference of an
embryo and a fetus. Opponents use the two terms interchangeably when there are very important
distinctions. Embryos are considered to be in the developmental stage between two weeks after
conception and six weeks. After six weeks, the embryos are now referred to as fetuses. However,
the embryos used in stem cell research are in the blastocyst-stage embryo, which is viewed as the
pre-embryo stage. This means that the embryos used in research are indeed alive, but they are
not human lives and do not deserve the same kind of respect as a developed human. In addition,
one might consider that embryos that are not immediately used or frozen are otherwise discarded
(Herold 120-122). It is better to freeze an unused embryo and use it later on for research rather
than discarding it all together. On the basis that blastocyst-stage embryos are not regarded as
human persons, stem cell research is morally permissible.

Embryonic stem cell research can provide our society with many cures and treatments to
diseases and illnesses for which we currently do not yet have a cure. For a suffering patient with
organ failure, this can mean the world to them. Along with this research comes astonishing new
methods and knowledge. We have gained a great deal of knowledge and there have been
significant drug discoveries through stem cell research. As we increase our understanding about
cell differentiation and growth, treatments, cures, and solutions, other medical problems can be
solved. Because of the advancements that can be made in medicine to improve human life, the
good to be gained outweighs the bad and, therefore, makes stem cell research morally
permissible.
