Using a powder made from pig bladders called extracellular matrix, scientists are now able to regrow human limbs. Yeah, you heard that correctly. My mind is too blown away to continue, so check out the links for more information.
From the CBS report:
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.
