In the field of medicine, the use of stem cells to better understand and treat diseases is causing growing controversy. Stem cells are unspecialized cells that have the ability to become any type of specialized cell and divide without limit (“Stem Cell Information”). Stem cells can be used to grow tissue to help patients with burns so they can heal faster and better (“Stem Cell Information”). Another major example is that these stem cells can be used to grow complete organs (“Stem Cell Information”). There are two types of stem cells that scientists and researchers work with: adult stem cells and human embryonic stem cells (“Stem Cell Information”). Embryonic stem cells can become any type of cell in the body, while adult stem cells can only become the cell type of their tissue of origin (“Stem Cell Information”). Another reason why these stem cells are very important is that they can even be used to treat diseases such as Alzheimer's disease, Parkinson's disease and even cancer ("Stem Cell Information"). The use of embryonic stem cells and adult stem cells has many advantages and disadvantages. At the same time, the ethical questions that embryonic stem cells raise are extremely important. In order to cure diseases that affect hundreds of thousands of people, those who do not support stem cell research must go beyond ethical rules so that scientists and researchers can conduct embryonic stem cell research to find a cure for these diseases. The main ethical question that seems to concern everyone is whether or not an embryo is considered a person. Various religious groups oppose the extraction of embryonic stem cells from human embryos. This is due to their belief that life is sacred from the moment of conception...... middle of article......rcures.org/article.php?uid=1000>.McLaren, Anne . “A Scientist’s Perspective on the Ethics of Human Embryonic Stem Cell Research.” Stem Cell (2007): 23-26.
