Don't like the jacket? It will grow on you, literally!

Scientists are developing a way to grow leather like clothing from tissue cultures. The tissues come from so-called immortalised tissue cultures where, like with cancer, the cells continue to grow unimpeded. I guess the idea is that it shouldn't offend the prolifers and the animal liberationist; you know the people, the rational caring ones that bomb the houses of people they suspect of being abortionists and vivisectionists. Just one thing though, being a bit nit-pickking, presumably, even a coat that grows itself is a living thing, sure it may not be sentient in any way we know, but where do you draw the line?
