In 2004, when Nancy Reagan, speaking at a Juvenile Diabetes Research Foundation event, she brought up the issue stem cell research. Former First lady Reagan said “Science has presented us with a hope called stem-cell research, which may provide our scientists with many answers that have for so long been beyond our grasp,” she said. “I don’t see how we can turn our backs on this. There are so many diseases that can be cured or at least helped. We’ve lost so much time already. I can’t bear to lose any more.” Stem cells have amazing potential; Like infants they have the potential to grow into anything. When stem cells divide they can eith continue to be a stem cell our grow into something else such as a brain cells, a muscle cell, a red blood cell.

First, they are unspecialized( or infant cells) cells capable of renewing themselves through cell division like mitosis. Second, under certain conditions, they can be forced to be made into a tissue or organ specific cells with special functions. In some organs, stem cells regularly divide to repair and replace worn out or damaged tissues. For example, when you get a cut or scratch and you see a scab come when it's healing. In other organs, however, stem cells only divide under special conditions. As when a piece of a liver is transplanted and your full liver grows back on it’s own slowly is also an example of stem cell regeneration. Until recently, scientists who were primarily worked in stem cell research only used two kinds of stem cells from animals and humans: embryonic stem cells and non-embryonic "somatic" or "adult" stem
