Stem Cells -- Ethics, Research, and Regulation Essay -- Embryonic Stem
alkali Cells -- Ethics, Research, and RegulationI. IntroductionEmbryonic stem mobile phone look into offers both great promise and great peril.- President George W. Bush, Aug. 9, 2001Stem cell research is not new but only recently has it start out widely known to the public because the benefits of the technology are coming enveloping(prenominal) to reality the field of stem cell biology is advancing at an incredible pace with new discoveries being reported in scientific literature on a weekly basis. Scientists first announced a method of growing immature stem cells in a testing ground in 1981, but the cells were from a mouse. It wasnt until five years ago that James Thomson (pictured to the leftP3) at the University of Wisconsin- Madison announced that he was able to sequestrate cells from the blastocyst of an early embryo.5 From research he gathered in the field of applied reproductive biology and mouse embryology, he was able to cultivate the first kind-hearted embryonic stem cell lines. At the similar time as Mr. Thomson, John Gearhart (pictured to the rightP4)reported the first derivation of human embryonic germ cells from the primordial germ cells located inside the fetal gonadal tissue that is key in the obtainment of eggs and sperm. Dr. Gearhart, working at Johns Hopkins University with other prominent stem cell researchers, was then able to develop pluripotent stem cell lines by isolating stem cells from early human embryos and grow them in culture. Most recent research is focusing on two types of stem cells pluripotent cells and adult stem cells that have been in clinical use for use but just recently were discovered to be able to develop into cells that have many of the characteristics of neurons. But even with exclusively the information known alrea... ... the National Bioethics Advisory Commission.4. National Institutes of Health Online. 27 August 2001.
