What happened to the mouse with the ear on its back?
How did the mouse get the ear on its back? The whole process involved making a scaffold that has the shape and the size of an ear. The material is man-made, biocompatible and bioabsorbable; it disappears over time.
Can a mouse grow an ear?
The “ear” was actually an ear-shaped cartilage structure grown by seeding cow cartilage cells into biodegradable ear-shaped mold and then implanted under the skin of the mouse, with an external ear-shaped splint to maintain the desired shape.

How are mice genetically modified?
Transgenic mice are made by using glass micropipettes to inject a solution that contains DNA from a chosen source into the nucleus of a fertilized mouse egg. At times, the foreign DNA will be integrated successfully into the chromosomes of the mouse-egg nucleus. The eggs are then transferred to a foster female mouse.
How do I make my mouse glow?

Dr. Charles Vacanti
“The work in our presentation today has been performed by more than 1,000 researchers over the past 20 years,” he said. In 1995, the Vacanti mouse, named after Dr. Charles Vacanti who created the “ear” grown on the back of this mouse, was a laboratory mouse that had what looked like a human ear gown on its back.
