[quote]Three years ago, Lee Spievack sliced off the tip of his finger in the propeller of a hobby shop airplane.
What happened next, Andrews reports, propelled him into the future of medicine. Spievack's brother, Alan, a medical research scientist, sent him a special powder and told him to sprinkle it on the wound.
"I powdered it on until it was covered," Spievack recalled.
To his astonishment, every bit of his fingertip grew back.
"Your finger grew back," Andrews asked Spievack, "flesh, blood, vessels and nail?"
"Four weeks," he answered.[/quote]

One of the things that encouraged them is the fact that, in general, fingertips will grow back. It's just that the standard medical intervention in the case of such an injury stymies this natural regeneration process - the drastic measures taken to close the wound and stop the bleeding often interfere with the natural healing process.

Because you're reading summary coverage from an nth party source which is simplifying something substantially more involved.
My suspicion is that this cannot, in its present form, be used to re-form complicated structures or even do much than provide basic functionality. The lack of sufficient photo documentation in the article makes me wonder if things like the fingerprint were accurately restored or not and if the new tissue actually has any measure of blood flow.
