Stem Cells
Stem Cell research is an application that scientist are developing and perfecting at a rapid pace. Nowhere in the world can a person pick up a newspaper, magazine, or listen to a news show without hearing of some new discover or development. The headlines look at where stem cells come from and how they should be researched. Scientists are getting stem cells from several sources, embryos, humans, and umbilical cords. The bolder statement seems to be the ethical and legal controversy of the stem cell research. Government officials and religious leaders around the world differ in their opinions. As the stem cell debate rages on in the United States and other countries, what is the best avenue to explore morally and ethically; embryonic, adult, or cord blood? All three of these approaches are very interesting, complex, and promising.Stem cells are master cells that have the ability to differentiate into other cell types, including those in the brain, heart, bones, muscles and skin. They are best described in the context of normal human development. Human development begins when a sperm fertilizes an egg and creates a single cell that has the potential to form an entire organism. This fertilized egg is totipotent, meaning th
In Asia, Nobuyuki Fukushima, deputy director at the bioindustry division of Japan's Ministry of Economy, Trade and Industry, said Bush's decision was in line with trends around the world. "Japan is heading toward permitting this research, so we can't say that the decision by Bush is wrong. But the pros and cons must be debated rigorously."(Ross) Hall, MiMi and Kiely, Kathy. "Proponents of Stem-Cell Research Put on Pressure." Sept. 2001. 20 Feb 2002. [http://www.findarticles.com/cf_0/m0CYD/18.html] Researchers are working on numerous procedures that could change the lives of people who are suffering from crippling diseases, cancers, and other non curable illnesses. Recent studies also suggest these cells may hold the secret to treating damaged heart tissue, nerve tissue in the spinal cord, to cures for some of our most baffling diseases, including Alzheimer's and Parkinson's. The debate about this issue is from where these cells are taken. There are there are several different sources where scientists can get stem cells. They can be extracted from embryonic cells or adult cells. The embryonic cells come from unneeded frozen embryos at fertility clinics, material that would routinely be discarded with the consent of the parents. Another source of the embryonic stem cells is from aborted fetuses. Adult stem cells are taken for the blood and organs of healthy adults. and Perspectives. Online. August 2000. 30 January 2002.
