I am not well versed in regenerative biology, but my girlfriend happens to be getting her PhD in that field. I sent her this link for comment and here's what she said:
From article: "The wounded Marine's recovery is particularly exciting for scientists as it involves the regeneration of skeletal muscle which ordinarily does not grow back"
From any book in any regenerative scientist's library: "It has been known for more than a century that skeletal muscle, the most abundant tissue of the body, has the ability to regenerate new muscle fibers after it has been damaged by injury or as a consequence of diseases such as muscular dystrophy (1)"
(in this case the reference = Carlson BM. The regeneration of skeletal muscle. A review. Am J Anat. 1973;137(2):119–149. View this article via: PubMed CrossRef)
Annoying! Maybe he is on to something that really does help quicken the natural regeneration response or promotes better healing or something, but no one will ever know because there are no controls. He has no mouse controls... he obviously can't do human controls and people are just slapping this stuff on there because... "at least it doesn't hinder the response". (but he could be charging billions for a placebo!)
Oh well. Science is stupid. The media is even dumber.
In other words: Slashdot, please stop posting articles from the Daily Mail. Also, on background, I know the doctor mentioned in the article, Badylak, was kicked out of his group for poor research practices that included trial by media instead of peer review. This sort of publicity piece is his MO.
