For a start, I wouldn't believe a word that Ironman says, I've done plenty of research, and had a few unhappy Gho patients email me for my opinion on what to do next.
You believe what you like and I will express my opinion when I like and my opinion is that it doesn't work. All the pictures I've seen so far have shown a very thin result in the recipient, it's not all about the donor you know.
My opinion is that regeneration does not exist anymore than perpetual motion.
