Awesome! *I’m* not grossed out by this.

A “living” jacket grown from mouse and human bone cells. The cells used, which are applied to a biodegradeable polymer base, come from “immortalized” cell lines–i.e., cells that divide and multiply forever once they are removed from an animal or human host (without harm or hurt); they are a renewable resource, if you will. The goal of the “semi-living” jacket is to create “victimless” leather. Currently, the jacket is still so tiny (it’s about 2 inches high and 1-and-a-half inches wide) it could only fit a mouse.
