According to the American Medical Association:. Adult stem cells can actually be found in both adults and children. Their name comes from the fact that they can be harvested from mature tissue without causing harm to the person from whom they are harvested. Embryonic stem cells, on the other hand, can only be derived from embryos, and the harvesting process destroys the embryos. From this basic introduction, it is already clear that embryonic stem cell research has far greater potential to be ethically problematic than adult stem cell research. However, embryonic stem cell research is also generally considered to have the greatest potential for delivering medical and scientific breakthroughs, due to the fact that they are even more flexible so to speak and undifferentiated than adult stem cells see Bongo and Richards.
From the medical perspective, stem cell research is viewed as very promising due to the fact that if stem cells can be introduced into patients with a range of illnesses, they could possible help regenerate the tissues and organs of the patients and thereby help heal illnesses and especially degenerative illnesses that are currently incurable.
For example, Lovell-Badge has indicated that diabetes, Parkinson's disease, and Huntington's disease are among the illnesses that could potentially be responsive to stem cell research Again, given that the potential of stem cell research is directly correlated with the plasticity of the stem cells in question, it logically follows that there will be an increasing push by scientists to focus research on embryonic stem cells if at all possible, due to the fact that they have greater plasticity than adult stem cells and thus greater potential to contribute to medical breakthroughs.
The moral dimension of the issue, however, has generally led to limitations being imposed on the capacity of scientists to pursue embryonic stem cell research. The organization Science Progress has provided a good summary of some of the main events that have marked the scientific history of stem cell research. These include:. These events were important due to the fact that scientifically speaking, the isolation of stem cells from other elements within the body would be a prerequisite for conducting rigorous research on stem cells themselves.
From this point, human scientific history over the course of the last decade and a half has been characterized by progressive breakthroughs in stem cell technologies, including:. Clearly, the scientific progress over the past several years gives great cause for hope. There has been a steady trend of scientists increasingly learning the secrets of stem cells and being able to apply their new knowledge to either research potential treatments or actually deliver effective treatments to human beings. Therefore, it could be suggested that anyone who has a real interest in seeing major medical breakthroughs happen which, presumably, would be almost everyone cannot afford to oppose the ongoing development of stem cell research per se. What there clearly can be controversy over, though, is how exactly the research agenda ought to proceed.
In order to more effectively address this dimension of the issue presently under consideration, it may be a good idea to turn now to the political history of stem cell research, or legislation that has surrounding the issue as it has developed over time. One of the clearest points that emerges regarding the political history of stem cell research and bioengineering in general , is that there has been ongoing controversy over the extent to which the federal government should fund research. This has proved to be a quite partisan issue. For example, in , Bush issued an executive order that placed significant restrictions on federal funding for stem cell research; and in , Obama countermanded this order with an order of his own called "Removing Barriers to Responsible Scientific Research involving Human Stem Cells" see Research America.
This, of course, is tied to broader political conflicts regarding issues such as religion and abortion. If the federal government is to spend tax money on stem cell research, then this would likely contradict the values of many Americans, and especially conservative Americans, regarding the origins of human life. This is likely why the main legislative barriers against stem cell research have always focused on embryonic stem cell research. Again, as has been noted above, significantly greater ethical dilemmas inhere to research with embryonic stem cells than to research with adult stem cells. A good example of such restrictions can be seen in the guidelines for stem cell research released by the National Institute of Health in , which stipulated that:.
Several important ethical points are exemplified by this statement, including that embryonic stem cells must be derived using private and not public funds and that it still is not acceptable to create embryos simply for the sake of harvesting stem cells from them and destroying them in the process. Over the course of the last several years, though, such regulations would seem to have become someone less salient both due to their relaxation under the Obama administration and to scientific innovations regarding adult stem cells, which have enabled scientists to somewhat circumvent the legislative debate surrounding embryonic stem cells.
This is because controversy over stem cell research generally tends to focus on the use of embryonic stem cells; but then, this leads to the more fundamental question of the legal, ethical, and metaphysical status of the embryo. In principle, if one grants that abortions are acceptable, then one must also grant that it is acceptable to create embryos specifically for the purpose of harvesting stem cells from them. To put it a little differently: insofar as an embryo is not understood as a living human being, there would be no reason for controversy to even arise regarding this matter.
Of course, there is a significant number of Americans who believe that life begins at conception, and that the embryo is thus in fact metaphysically a living human being. If this were the case, then the manufacture of embryos simply for the purpose of destroying them would be horrific, insofar the destruction of each embryo would then be morally and conceptually equivalent to murder. If this paradigm is accepted, then whatever benefits could be produced by embryonic stem cell research would clearly be outweighed by unacceptability of the atrocities that would need to be committed in order to achieve those benefits. Clearly, this conflict ultimately surpasses the bounds of science itself and is grounded in the differing religions and broader worldviews of different groups of people within the nation.
As Robertson has written:. Good Debate Topics for College Students College students are young adults who have informed opinions and the wherewithal to express themselves in a concise and intelligent manner. Given below are a few informative speech topics for college students. We will see that the body is controlled by an information highway known as the nervous system. A collection of hundreds of billions of specialized cells that transmit information between different parts of the body, a collection of. Peter Olson Mrs. A special type of cell can help with almost any problem with the human body. It is my belief that each of you should rethink about stem cells. Stem Cells is a unique type of cell that can change into any type of cell in the body.
I've divided my speech into three parts: First, how to get stem cells. Next, the uses of stem cell. Finally, why people should take treatments. First, how to harvest or to gather stem cells. There are many ways to gather stem cells and there are many different types of stem cells. There are stem cells from the bone marrow and peripheral blood. Stem cells in the bone marrow are times more concentrated than the other ways to gather the cells. The doctor inserts a syringe into the donor's hip and collects roughly mL of marrow.
