Researchers have discovered the genetics behind lizards growing their tails back when they fall off. Scientist have studied the ‘green anole lizard’ who loses its tail when caught by a predator. Once it loses its tail the lizard can regenerate it. Researchers have discovered that green anole lizards turn on 326 genes when regenerating their tails. This includes genes involved in embryonic development which is a response wound healing. Regeneration also doesn't happen quickly; lizards take over 2 months to regenerate their tails. Lizards regenerating structure is very complex with cells growing into tissues along the tail. One cell that has been discovered for regeneration is satellite cells. They develop into skeletal muscles. Since
