U.S. military researchers grow new limbs, organs
American military researchers say they have unlocked the secret to
regrowing limbs and recreating organs in humans who have sustained
major injuries.
Using "nanoscaffolding," the researchers have regrown a man's fingertip and the internal organs of several test subjects.
The
technology works by placing a very fine apparatus called a scaffold,
which is made of polymer fibres hundreds of times finer than a human
hair, in place of a missing limb or damaged organ. The scaffold acts as
a guide for cells to grab onto so they can begin to rebuild missing
bones and tissue.
