Stem cell treatment of degenerative eye disease May Comparison of 2D and 3D neural induction methods for the generation of neural progenitor cells from human induced pluripotent stem cells December The cells are grown in laboratories where tests are carried out to investigate fundamental properties of the cells. The controversy surrounding stem cell research led to an intense debate about ethics. Up until the recent years, the research method mainly focused on Embryonic Stem Cells, which involves taking tissue from an aborted embryo to get proper material to study.
This is typically done just days after conception or between the 5th and 9th week. This is probably an important advancement in stem cell research, since it allows researchers to obtain pluripotent stem cells, which are important in research, without the controversial use of embryos.
There were two main issues concerning stem cell research with both pros and cons:. The first issue is really not just about stem cell research, as it may be applied to most research about human health. Since , the second point, concerns about the methods involved, has been less debated, because of scientific developments such as iPS. As you will most probably notice, the following arguments are not exclusively in use when talking about stem cell research. Stem cell research can potentially help treat a range of medical problems.
It could lead humanity closer to better treatment and possibly cure a number of diseases:. Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society.
The controversy regarding the method involved was much tenser when researchers used Embryonic Stem Cells as their main method for stem cell research. These points are based on the old debate about the methods of stem cells research, from before Since then, scientists have moved on to use more ethical methods for stem cell research, such as iPS.
This section serves as an illustration of the difficult evaluations researchers may have to analyze. The stem cell-research is an example of the, sometimes difficult, cost-benefit analysis in ethics which scientists need to do. Even though many issues regarding the ethics of stem cell research have now been solved, it serves as a valuable example of ethical cost-benefit analysis. The previously heated debate seems to have lead to new solutions which makes both sides happier.
Stem Cell pros and cons had to be valued carefully, for a number of reasons. When you are planning a research project, ethics must always be considered. If you cannot defend a study ethically, you should not and will not be allowed to conduct it. You cannot defend a study ethically unless the presumed cost is lower than expected benefits. Why was the debate regarding the stem cell research so intense? First, it was a matter of life - something impossible to measure.
And in this case, researchers had to do exactly that: Both an abortion and someone dying, suffering from a possible curable disease, is a tragedy. Which have the highest value? Does a big breakthrough in the research justify the use of the method in the present?
Would the benefits of studying abortions outweigh the costs? The choice was subjective: Nobody knows all the risks or all the possible outcomes, so we had to value it with our perception of the outcome. Perception is influenced by our individual feelings, morals and knowledge about the issue.
Second, at the time we did not know whether the research was necessary and sufficient to give us the mentioned health benefits. Third, other consequences of the research are uncertain. Could the research be misused in the future or not? We simply do not know.
A discussion of the pros and cons, background, and latest developments in the ethical debate over embryonic stem cell research.
Stem cell research and its funding have caused enormous controversy over the past decade. Stem cells are pluripotent cells present in all living organisms. These cells can differentiate into any.
Stem Cell Research Paper Sample Summary Page A stem cell is specified type of cell possessing unique capability to renew itself and produce specialized types of cells. Research Papers on Stem Cell Research Stem Cell research papers on the pro-argument paper on stem cell research on the level of the State of California. This is a medical health research paper on stem cell research.
Pros and Cons of Stem Cell Research - Embryonic Cells The pros and cons of stem cell research come to the surface when we examine the third source of stem cells - embryonic cells. Embryonic stem cells are extracted directly from an embryo before the embryo's cells begin to differentiate. At this stage the embryo is referred to as a "blastocyst.". The debate of the pros and cons of stem cell research clearly illustrate the difficult ethics evaluations researchers sometimes must do. This article is a part of the guide.
