Regrow Lost Fingertips with... Pig Bladder Extract?

The AP is reporting (via MSNBC) [1] that two men who lost their fingertips in accidents, have regrown their fingertips using a pig bladder extract from ACell Inc. This sort of technique raises a lot of eyebrows, but something in the article I did not know is that young children can naturally regenerate a lost fingertip.

If Spievack, now 68, had been a toddler, things might have been different. Up to about age 2, people can consistently regrow fingertips, says Dr. Stephen Badylak, a regeneration expert at the University of Pittsburgh. But that’s rare in adults, he said.

An interesting article that gives some insight where some scientists are forcasting for the future.
