Stem Cell Research
...f great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body.” (http:///www.news.wisc.edu) Adult cells are also used but they are not as useful for research purposes as embryonic stem cells. This is mainly because adult cells are already specialized. This means that their potential to regenerate damaged tissue is very limited. “Adults do not have stem cells in many vital organs, so when those tissues are damaged, scar tissue develops. Only embryonic stem cells, which have the capacity to become any kind of human tissue, have the potential to repair vital organs.” (http://www.news.wisc.edu). The strategy of these scientists is simple. Their plan is to take cells of a healthy embryo and transplant them into a person inflicted with any type of disease. Replacing faulty cells with healthy ones offers hope of lifelong treatment. Similarly, failing hearts and other organs, in theory, could be shored up by injecting healthy cells to replace damaged or diseased cells. ( http://www.news.wisc.edu ) Man...
