Stem Cell Ethics The study of stem cells have brought about many recent ethical questions and been a topic in many recent ethical debates. What is all the talk about? What exactly is stem cell research and why does it raise so many ethical questions? Stem cell research is on the forefront of regenerative medicine and biological science. It is the study of certain cells in the inner mass of the embryo that are produced a few days after the embryo forms during the blastocyst stage. They are the most primitive of all human cells. They are undifferentiated cells, which mean the cells are not designated to be any special type of cell, such as a nerve, muscle, or skin cell. The cell's specialization is later influenced by the molecules, which are usually proteins that surround the cell (Marshak 220-223). The proteins are typically produced by the mother, but under certain laboratory conditions, distinctive proteins can be introduced and a definite, mature cell type is produced. The cells that are produced could be implanted into a subject to replace worn out cells, or cells that have been destroyed due to disease or injury. There are a few problems with the process. The most common being is the same as any other transplant, the body doesn't accept the new cell stem cells if the cells aren't exactly the same as the patients; instead the body's immune system recognizes them as unwanted cells and rejects or destroys them often causing more damage to the body. The most common use of stem cells is bone marrow transplant. Some adult stem cells are usually found in bone marrow, when the marrow is transplanted the cells regenerate and help replace the failing surrounding marrow. However, this type of procedure doesn't involv... ... middle of paper ... ...it also must be closely guarded to make sure it doesn't lead to simply breeding humans just to harvest their organs and making human life immortal. As technology increases and more about stem cells is known more ethical debates will undoubtedly rise. Stem cell research will almost indefinitely continue to attract public attention for many years to come. Works Cited National Research Council. "Stem Cells" Washington, D.C.

Stem cell research has always been a widely debated topic in 'social and political forums' ever since the case of Roe vs. Wade in 1973. In that case the Supreme Court gave women the right to have an abortion whether or not they have a medical reason to. Whereas beforehand 'they needed a medical reason'. This "sparked controversy" over stem cell research with aborted fetuses. For many of those in favor of using fetal tissue for research it has too much "potential" in the future of medicine in terms of providing cures for diseases and "". Those against fetal tissue research believe it unethical to take one human life in order to preserve another.
Stem cells are the building blocks of the human body. Embryos consist of unspecialized stem cells that transform into the various specialized cells in the body such as cardiac, muscle or bone cells. Fetuses also have stem cells. However, the stem cells are divided into types like muscle, bone or nerves and don't perform a specialized function. Surprisingly, adult bodies also contain stem cells. In adults, stem cells are undifferentiated but limited to specific tissue type. When needed, the stem cells transform into the cells needed for repair and maintenance. The most common source of adult stem cells is bone marrow. Researchers also acquire stem cells from umbilical cords. Without stem cells, embryos could not develop into fetuses and adult
“Through the isolation and manipulation of cells, scientists are finding ways to identify young, regenerating ones that can be used to replace damaged of dead cells in diseased organs. This therapy is similar to the process of organ transplant, only the treatment consists of the transplantation of cells rather than organs. The cells that have shown by far the most promise of supplying diseased organs with healthy cells are called stem cells.” (Chapter Preface)

...ns of a morally questionable nature. It is necessary that our practices remain ethical and that we uphold the value of a human life, as this is the cornerstone of human society. Embryonic stem cell research is one such operation that forces scientists, policy makers, and the larger society to define what constitutes a human life and to find an answer to the crucial question: Is it morally acceptable to violate the rights of a human life for the for the sake of medical progress?
Stem cell research has been a hot topic for debates all over the country. People from every major religion and walks of life are always trying to find the morality behind stem cells. However, not all religions have the same opinions. Catholicism, Buddhism, different divisions of Christianity and governments all over the world, have very different views of what rights embryos have. Some support the research and some oppose it. But there is also a whole group of people that do not know what to think about the issue.
Which is why discussing the legality of researching stem cells is complicated. Scientific discoveries and advancements in healthcare are some of the most important things on this planet. However, people's faiths and morals are important as well and must be respected. No one can say absolutely whether or not stem cell research is ethical since the answer stems from opinions. Whether you follow Divine Command Theory or Utilitarianism, both are simply opinions on what is right and
The conflict surrounding stem cell research is, with ethical consideration, whether it is a good or bad. The majority of Americans are advocates due to the possibilities of medical advancement, thus saving thousands of lives. Those in opposition believe that it is against
Despite the unquestionable gains that embryonic stem cell research has brought and may continue to bring to medicine, I believe the ethics and morality of stem cell research is questionable. Embryonic stem cells are taken from a human embryo, which is “the developing organism from the time of fertilization” (conception) “until the end of the eighth week of gestation, when it becomes known as a fetus” (National Institutes of Health). These embryos are fertilized in an in vitro fertilization clinic, and their stem cells are extracted from their inner cell mass of the blastocyst after three to four days. They must be extracted because after five days of the embryonic cell’s development, these undifferentiated stem cells no longer exist. In the process of extracting these cells from the infer mass of the blastocyst, the human embryo is destroyed. Since human life begins at the moment of conception (when sperm fertilizes an egg), the destruction of the human embryo is the destruction of a human being. Killing a human being and disregarding the irrevocable value of human life is morally wrong; therefore, embryonic stem cell research is not morally acceptable. I will be arguing this point throughout the paper, taking into consideration counterarguments and building upon others that are also against embryonic stem cell research.

Stem cell research is becoming an issue that is one of the most profound of our time. The issue of research involving stem cells derived from human embryos is increasingly the subject of dinner table discussions and a national debate. The issue is confronted every day in laboratories as scientists ponder the ethical consequences of their work. It is agonized over by parents and many couples as they try to have children, or save children already born. The issue is debated within the church, with people of different faiths, even many of the same faith coming to different conclusions. Many people are finding that the more they know about stem cell research, the less certain they are about the right ethical and moral conclusions.

...there are some risk factors in using stem cell for therapeutic approaches, hematopoietic stem cell therapy by bone marrow transplantation has already been proofed to be safe if donors’ background and screening, cell contamination, HLA matching and opportunistic or nosocomial infections during immunocompromised period were carefully monitored and controlled. Still, other types of stem cell therapies, despite of their good therapeutic efficacy, are remain in experimental stage and need more data to support and demonstrate the safety in clinical trials. More understanding of stem cell biology is also required in order to keep stem cell under controlled and avoid some complications that they might cause. So, to pave the way for successful stem cell therapy, research in this extent is needed to pursue to maximized therapeutic efficiency with highest safety in patients.
