Stem cell - Research Paper Example â€Å"Mouse embryonic stem cells treated in culture with a growth factor and then injected into the liver reverse a form of hemophilia in mice analogous to hemophilia B in humans, the new study shows.† (Stem Cells Treated with Growth Factor) Stem Cell Research- a clash of Science vs. Ethics, could well be a debate that might go on for generations as every individual has a different opinion about the subject. Should we allow doctors to play God and reverse our own destiny? Should we strive to provide cures that reverse the processes of injury and death? Or do we hold strong on our religious and moral aspects? These are the sorts of questions that have sparked the massive debate we have today. The purpose of our study, though, is not to argue about one particular stand point but to discuss both the view points and finally to allow readers to draw their own opinions and conclusions. In addition the process has been facilitated by providing an integrative review that details previ ous research, theories, explanations and answers and then counteracting them with questions and objections so that at the end of our research readers can make their own rationalistic conclusion. The Beginnings of Stem Cell Research Stem Cells, as defined by The National Institute of Health, are cells that have the ability to develop into different cell types within the body. Two facets make them incredibly important: Firstly, they can renew themselves during cell division and secondly, when grown under certain conditions, they can achieve specialized functions. These cells differentiate and form almost all the tissues of the body- skin, lung, brain, heart and muscle tissues among others. Stem cells can also be divided into two types: Embryonic stem cells and Adult stem cells which differ in both function and characteristics. According to the UK Stem Cell Foundation, stem cell work was first conducted in the early 1900’s with the discovery that white blood cells, red blood cel ls and platelets all arose from the same source. However, it was not until 1963 when Ernest A McCulloch and James E Till noted â€Å"the self-renewing activities of transplanted mouse bone-marrow cells† that confirmed such theories. Adult stem cells now play an integral role in chemo and radiation therapy as well as in other fields of biotechnology as they are grown and replicated in the lab. The discovery by James Thomson and his researchers from Madison University really helped to put Stem Cell Research on the map (Boyle, A., 2005). In 1998, for the first time ever, he isolated human embryonic stem cells from fertility clinics and then harvested them in the lab. This attempt along with the cloning of Dolly, the Sheep, two years earlier, caused a major ripple within the community. The Pros and Cons of Stem Cell Research Pros Stem cell research has paved the way for scientists to decipher â€Å"how we are made or formed and try to reverse problems† (Richard Hamilton, n .d). It has been described as having â€Å"limitless potential† (McLaughlin, 2009) by many as it can aid in finding cures for diseases such as Parkinson’s, Alzheimer’s, Stroke, Heart Disease, Multiple Sclerosis and Diabetes, and hundreds of rare systemic immune disorders (Drlica,1997, p279) 1998). . There have been a number of researchers confirming the clinical application of stem cells. Stojanoski et al (2009), stated that stem cells taken from the peripheral
