This is pretty amazing if it's true... "extra-cellular matrix" powder that can regrow a fingertip. With pictures, some gruesome.
Scientists are claiming an amazing breakthrough - regrowing a man's severed finger with the aid of an experimental powder.
Four weeks after Lee Spievack sliced almost half an inch off the top of one of his fingers, he said it had grown back to its original length.
Four months later it looked like any other finger, complete with "great feeling", a fingernail and fingerprint.
I'm skeptical, but hey, if it's real then it's an amazing breakthrough. I'm sure we'll hear more about this "pixie dust".
Looks like my skepticism was justified.
But Professor Stephen Kaye, a consultant plastic and hand surgeon at Leeds University, poured cold water on Dr Badylak's claims.
Asked if he was surprised that Mr Spievack's finger "grew back" he said: "Not in the slightest."
Prof Kaye added: "The pictures I've seen on the web show a wound I would have expected to heal and regenerate in any case.
"The end of the finger is extremely good at regeneration. The pictures we've seen on the web show no evidence of loss of bone, nerve or tendon material, but regeneration and repair of skin - which is exactly what the fingertip does."
He added that the photographs appeared to portray a "very commonplace transverse amputation of the very end of the fingertip" and not someone who had lost the last phalanx of his finger, as Dr Badylak claimed.
Well yeah, if there was no loss of bone, nerve, or tendon, then the regrowth is much less interesting.
