The mouse has a gene that makes areas containing stem cells that could grow into nerve or brain cells glow green under fluorescent light. Scientists expected to see a mouse with a green head when they stuck it under the lamp. Instead, they got a lovely all-over green display, evidently because hair follicle stem cells are very similar to brain stem cells. Injecting them into injured mice regenerated their spinal cords.
