you've posted a completely different article! It has nothing to do with your original youtube post, to which you claimed that they can even grow nerves. That was the post to which I replied that had nothing to do with nerves. Stay on track please. If nerve fibers were being grown along with the tissue, then I'm sure someone would have commented on it. I heard tissue, bones,, etc, but no mention of nerves. You cant just assume that it is happening.
