Well things have progressed quickly, and as reported in the Ottawa Citizen via Canwest News Services:
American military researchers say they have unlocked the secret to regrowing limbs and recreating organs in humans who have sustained major injuries.Previous research in England (2006) had shown that nanoscaffolding could be used to grow skin for grafting in severe burn cases. And in Australia in February, a PhD student released research papers showing how nanoscaffolding can be used to repair nerve damage.
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. The tissue grows through tiny holes in the scaffold, in the same way a vine snakes its way up a trellis.
After the body part has regenerated, the scaffold breaks down, is absorbed into the person's body and disappears entirely.
The military plans to announce the breakthrough at the 26th Army Science Conference in Florida next month.
The next question is, how soon will these types of procedures be readily available to the general public?
It never ceases to amaze me, the scientific advances I've seen over my 65 years and I expect to see many more before I shuffle off this mortal coil. At least, that's how I see it from Between Keyboard and Chair.
