One Step Forward: Salamanders and Limb Regeneration
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.
