Stem cells have the potential to reverse ailments that previously had no guaranteed cure. Their unique pluripotent characteristic allows them to differentiate into virtually any of the cells in the body. This means that stem cells can be used to repair or regenerate the tissue/organ that is damaged or diseased in these individuals. These pluripotent cells are specifically referred to as embryonic stem cells, which are what most people consider when they think of the topic and are the ones that are the most controversial. Since these cells are not yet differentiated into their specialized cells, they must come from very early embryos; typically no older than a few days old. As a result of the extraction of stem cells, the embryo is destroyed, and can no longer be salvageable for further development. This becomes the root of a lot of the ethical and moral concerns that individuals have pertaining to this field of research. Essentially we have brought ourselves back into the surgeon case. However, we have to understand that the embryos that are currently allowed to be used for research are only coming from excess in vitro fertilization. In other words, when the fertilized eggs that patients no longer need and do not wish to pay to store, they are destined to be destroyed. Nevertheless, they have the option to donate them to research, which is where these embryos and therefore the embryonic stem cells that are currently being tested are originating from. Therefore, taking a utilitarian approach to this, we should be able to treat the greatest number of individuals while inflicting little harm on society.
