The generation of a ball of mouse skin through stem cell work has created excitement among the the scientific community about possible new insight in skin formation — especially on humans.

A ball of mouse skin could lead to new insight in human skin generation


A group of researchers from the Indiana University School of Medicine were trying to develop inner ear tissue of a mouse using stem cells. What they ended up with was much different — and possibly a major breakthrough in understanding skin formation.

A human ear.

This new treatment could combat hearing loss by regenerating hair cells in the inner ear
