Penny Jones Dr. James Mayall Ethics in Action 01 April 2010 The Ethical Implications of Embryonic Stem Cell Research Stem cell is defined by Webster’s New World Medical Dictionary as‚ “one of the human body’s master cells‚ with the ability to grow into any one of the body’s more than 200 cell types (Webster’s New World Medical Dictionary‚ 2000).” The ethical implications of stem cell research; particularly with regards to embryonic stem cell research‚ has become an increasingly popular topic

standings are tested when scientist and theologist go head to head in the debate over "stem cell research". In November 1998‚ two independent teams U.S scientists reported that they had succeeded in isolating and culturing stem cells obtained from human embryos and fetuses. Because many diseases result from the death or dysfunction of a single cell type‚ scientists believe that the introduction of healthy cells of this type into a patient may restore lost or compromised function. The research of stem cells

It is used in prescription and over the counter drugs. It increases blood pressure‚ mental alertness‚ and gastrointestinal motility. Cardiovascular development with caffeine and other small molecules can be studied relatively easy using zebrafish. The cardiovascular system is complete in two days after fertilization

Pre-implantation genetic diagnosis (PGD) is a technique used to test the genetic abnormalities of an embryo through in vitro fertilization (520). With PGD‚ those embryos with genetic defects (in this case those embryos with a deaf gene) are rejected while those that are mutation free are kept to be implanted into the mother (520). There is controversy on whether it is acceptable to discard those embryos with high risk of mutations such as in the case of Garfield and Lichy. Garfield and Lichy are fighting

religious people. They believe that these scientists are murderers because in the process of harvesting the stem cells‚ they take away the inner cell mass from a real embryo which stops the embryo from developing. They consider the four-day old embryo as a real living thing with a soul and they claim that the scientists are killing the embryos. However‚ scientists from the stem cell research program in the University of Michigan state that “stem cells are derived from blastocysts that have only developed

causing restriction was George W. Bush’s vetoing of H. R. 810. This would have fueled stem cell research with the donation of embryo‚ from fertility clinics‚ that would have been thrown away otherwise. This veto restricted stem cell research facilities to use of embryos coming from the small number of sources from before. Bush’s based his decision off the morality conflict that embryos are destroyed in the process of harvesting of stem cells. This policy was reinstated by president Obama “in 2009‚ calling

type of research is the status of the human embryo. When the inner cell mass of the embryo is taken‚ the embryo dies. The reason for this is because the inner cell mass is what forms the three germ layers of the human body‚ so without it the embryo will no longer develop. People who are against the harvesting‚ research‚ and use of these special cells are known to be "pro-life." They are generally religious people who believe that the four-day-old embryo has a soul and is plainly murdered when harvested
