When a salamander gets into a tough spot with a predator it can shed and regrow it’s tail, limbs, and most of it’s major body parts. Some worms can even regenerate their entire bodies after being cut in half. But what is it that triggers their stem cells to heal in such a drastic way, and how could this same response be triggered in humans? Scientists have recently discovered a “master control gene” called Early Growth Response that is also present in humans so what could this mean for us?
This article explains some of the ins and outs of cell regeneration and how it might not be the presence of certain genes but rather, how they’re wired together that makes this level of cell regeneration possible.
