The darker side of stem cells

An investigation by Nature has found that patients in Texas are receiving unproven stem-cell treatments. The state and the company involved need to ensure that they follow FDA guidelines.

Stem cells offer the hope that one day they will be able to cure a huge range of disorders. But too many people are promising those cures to patients now, long before there is any evidence that they work. These claims are potentially misleading at best, and at worst could be downright harmful.
