BAD NEWS ON ADULT STEM CELLS: “Such cells are seen as the potential key to the treatment of certain muscle diseases. However, a study currently being conducted at Bonn’s University Clinic has produced some sobering findings: although the cells are able to migrate into the muscle fibres, they do not generally take on any tissue-specific functions. This, according to the Bonn medical scientists, means the cells would not serve as a substitute for defective muscle cells.”

There’s still a lot of stem-cell science to do before people can claim that one approach or another is clearly the best. Which is why we should be doing the science.
