Stem Cell Research: Making Choices and Ethical Concerns, Pro's and Con's
As the world becomes more technically advanced, it will be necessary to make decisions on some very complex issues. For example, many people are grappling with their thoughts on stem cell research. There has been so much written on this topic, for and against, it is difficult to assimilate all the information. Stem cell research is opening the door to many possibilities that will have a major impact on the future. It is important for the topic to be clearly explained, so individuals of all backgrounds, not only scientists, but lay people, older students and young adults as well, can look at the options and make a clear decision. A stem cell is a cell from which other cells can develop. One of the major discoveries in 1998 was when researchers successfully isolated stem cells from human embryos and aborted fetuses. Many believe that due to stem cell research and regeneration, people living in future decades may have no concern about major diseases, disabling injuries and aging (Viegas, 2003, p.1.). They look forward to additional stem cell breakthroughs. Other individuals, however, believe that stem cell research is unethical or are afraid of how this technology could be used for negative purposes in the future and would like i
New advances are happening every day in the field of stem cell research and genetics. Thus, the ethics of embryonic stem cell use may soon become moot. For example, scientists are making great headway with the use of adult stem cells. Researchers at Harvard Medical School expect that within five years adult stem cells will be used as a treatment to cure blindness caused by macular degeneration. Within 10 years, people may be routinely treated with their own stem cells in a clinic using a two-hour process. To understand the pros and cons of stem cells, it is necessary to know how they are obtained. Some stem cells can be extracted from the bone marrow or peripheral (nerve) system of adult cells. These are difficult to extract, but superior in use to embryonic stem cells. Other stem cells come directly from the embryo before its cells begin to differentiate (take on human form). In the 3- to 5-day-old embryo, or the blastocyst, special stem cells in the tissues will later become such bodily parts as the the heart, lung and skin. This use of stem cells from embryos makes many people concerned about the nature of life, degree of intervention into human cells and reproduction, and the overall meaning of existence. It has to be one of the most pressing issues that has ever confronted present-day society. There are three main issues of concern when using embryonic stem cells. First, and foremost, the derivation of stem cells from living embryos or aborted fetuses is associated with the ongoing controversy of when life begins and the ethics of abortion. For many people, an embryo is already considered a
