The Pace of Stem Cell Research

Forbes offers a reality check on the pace of stem cell research towards cures for age-related and other conditions. "Slow and steady" they say, although I'd debate the steady part of that - stem cell research has proceeded under the near-constant threat of local and national criminalization or other restrictions. The article is clear about the limitations of adult stem cells: "The greatest limitation of adult stem cells is that they can't regenerate all types of cells because they are specialized for definite cellular functions. Furthermore, it is impossible to extract certain adult stem cells, such as those that could regenerate brain tissue, without killing the donor." Overcoming these limitations requires embryonic stem cell research.
