Over the years numerous research groups have claimed the existence of novel stem cell or stem cell like populations in various tissues. Stem cells spend much of their time dormant, but with the right signals or other form of control, it is plausible that they could be directed to greater activity, enhancing tissue regeneration. This is a slow process of discovery, however, usually accompanied by debates over whether or not cells of a claimed type actually exist, whether the research methodologies used in published studies are sound, and so forth. It is wise not to become too excited over any specific claim, but the prevalence of this sort of research suggests that there may be something there. The results noted here are an example of the type, in this case for the central nervous system. The potential to induce regeneration of nerve tissue and the brain is a topic of great interest in the research community.

A major goal of regenerative research is to repair the brain efficiently following injury, for example due to stroke, Alzheimer’s disease or head trauma, disease or ageing. The brain is poor at repairing itself; however, it may become possible to improve
