Dr. Ding focuses on reprogramming skin cells into neural stem cells using the existing iPS technology -- but with a twist. Dr. Ding never lets the cells enter the pluripotent state of iPS cells, in which they could develop into any type of cell. Instead he uses yet another cocktail of factors to transform the skin cells directly into neural stem cells. Avoiding the pluripotent state is important because it avoids the potential danger that "rogue" iPS cells could develop into a tumor if used to replace or repair damaged organs or tissue.
