This sounds kind of cool. I wonder if it could be used to repair scarred lung tissue. If their technique actually works, that is.

Blood could generate body repair kit

A small company in London, UK, claims to have developed a technique that overturns scientific dogma and could revolutionise medicine. It says it can turn ordinary blood into cells capable of regenerating damaged or diseased tissues. This could transform the treatment of everything from heart disease to Parkinson's.

If the company, TriStem, really can do what it says, there would be no need to bother with conventional stem cells, currently one of the hottest fields of research. But its astounding claims have been met with bemusement and disbelief by mainstream researchers.[NewScientist.com]
