Lessons from Salamanders: Could Humans Ever Regenerate Limbs?

In Brief Salamanders, which have the ability to regenerate parts of their body, may one day provide the key to helping humans generate lost limbs. Scientists are studying these animals to understand precisely how the process works and how it might be applied to other species. Even if possible, there will likely be significant challenges. These include the length of time that may be required to regrow limbs and concerns about possible...

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.
