Imagine having to undergo an arm amputation due to a severe trauma or infection. Sure, you could wear a prosthetic to perform some daily functions, but you could never get the arm back. Or could you?
Looking for a better answer for amputees, researchers have turned to nature’s expert in limb regeneration, the salamander. The human body initially reacts similarly to that of a salamander. We immediately form a scar to prevent the open wound from infections and major blood loss, but our bodies stop there. Unlike the salamanders, we cannot reactivate or naturally form a blastema to regenerate a new limb in a few weeks.
