Few years back I remember reading a story about the guy who lost his finger in an accident and then regrew it by dipping it into some kind of a powder. Edit: found it! >The magical formula to regrow a finger apparently includes a doctor, a pig, and some “pixie dust.” This is no fairytale, though; this is a medical breakthrough being explored at the University of Pittsburgh, Pa. In Science Channel’s video, “How to Grow a New Fingertip,” Dr. Stephen Badylak from the university explains regenerative medicine has the potential to grow a whole human body. https://www.youtube.com/watch?v=DtBUM51t4iw https://www.youtube.com/watch?v=DtBUM51t4iw http://www.medicaldaily.com/pulse/magical-pixie-dust-pigs-bladder-helps-man-regrow-human-tissue-severed-finger-346154 http://www.medicaldaily.com/pulse/magical-pixie-dust-pigs-bl...

Perhaps I'm wrong, but isn't this how scientists regrow organs? The matrix is used as the structure which gets implanted with the person's stem cells which activates growth. In the end the organ isn't even rejected by the body. However, growing limbs out of the same material is just mind-bending.

> In Science Channel’s video, “How to Grow a New Fingertip” Just wow! This story is about actually regrowing a finger on the man's hand. It's so incredible, I'd skeptical. Is this really correct? Why didn't they make a time lapse video of the man's finger regrowing -- even taking just one photo per day. That would have been the obvious thing to do, but they didn't do it (or didn't show it). UPDATE: On further research, I guess it was just too good to be true. Here's one rebuttal to the claims from the exuberant video: https://www.theguardian.com/science/2008/may/01/finger.claim https://www.theguardian.com/science/2008/may/01/finger.claim tl;dr: The finger was not so badly injured. It healed rather than regrew.

  Here's some pictures of finger regeneration. DO NOT open these images if medical imagery bothers you. They're gruesome :) http://www.mebo-international.com/sites/default/files/field/image/Fig%202.GIF http://www.mebo-international.com/sites/default/files/field/... Page with a lot more pictures: http://www.mebo.com/a/books/HUMAN/2011/0221/2934.html http://www.mebo.com/a/books/HUMAN/2011/0221/2934.html These examples are from stem-cell activation therapy: http://www.space-age.com/fingertipregeneration.html http://www.space-age.com/fingertipregeneration.html
