Okay, I was just reading a Wired article about some Australian scientists that are trying to grow a “stitchless [and] victimless” leather coat from living human and mouse cells. You can find the article here. They are using the mouse cells for connective tissue and using human bone cells to try and create a firmer outer skin for the coat.
Okay, they are also doing a lot of other weird stuff through this sort of creative cell growth, and some of it is a little creepy, but I cannot help thinking this is pretty cool. I mean creepiness aside, it is pretty amazing that we are capable of something like this and that it is working.
