1. It is one of the most misunderstood areas of the pro-life movement
2. I have the least amount of knowledge and experience in this area
To have it simply put (which is really the best I can do) using embryonic stem cells kills the embryo. An embryo is fully a human being with all the DNA necessary to develop a unique person. To say something more positive - there are live-saving and cure giving alternatives. These alternatives include adult stem cells and cord blood. Both options are just as medically valuable in my understanding, if not more. I have found a great resource that provides an informed and scientific argument for funding adult stem-cell research and not embryonic cell research
Adult Stem Cells 'are currently the only type of stem cell commonly used to treat human diseases...The clinical potential of adult stem cells has also been demonstrated in the treatment of other human diseases that include diabetes and advanced kidney cancer.'

I actually found this quote on a different website that has more information on this topic than I could possibly hope to process. Feel free to browse here for more information.
