What do the supporters of embryonic stem cell research have to say?
Many scientists believe that creating new embryonic stem cells and using cloning techniques will provide the most knowledge and new therapies. As discussed before, cloning could provide transplant therapies that eliminate the chance of rejection, hence saving many more lives. Also, embryonic stem cells are more promising than adult stem cells not only because they are pluripotent, but also because adult stem cells are more likely to have undergone damage through all the toxins and pollutants that people are exposed to throughout their lives. These damages could cause adult stem cells to behave differently and lead to less effective medical treatments. (Healy 2003) Scientists also believe that if it’s not right to create and clone embryonic stem cells, then there shouldn’t be as much debate over the use of existing embryos produced from IVF (In Vitro Fertilization) treatments. For each treatment, thousands of embryos could be produced, and only a few are selected for implantation. These
