Vacanti Earmouse


The Vacanti mouse was a laboratory mouse that had what looked like a human ear grown on its back. The ‘ear’ was actually an ear-shaped cartilage structure grown by seeding cow cartilage cells into a biodegradable ear-shaped mold.¬†The earmouse, as it became known as, was created by Dr. Charles Vacanti, an anesthesiologist at the University of Massachusetts and Dr. Linda Griffith-Cima, an assistant professor of chemical engineering at M.I.T. in 1995.
