Will Humans Ever Be Able to Regenerate Limbs?

Based upon the limitations of the human body and modern science, however, it's not likely that humans will be able to regenerate missing limbs anytime soon. When salamanders lose a limb, nearby skin cells seal the wound, forming a structure scientists call the wound epidermis.

How close are we to regrowing limbs?

In humans, an embryo fewer than 8 weeks old can fully regenerate a lost limb — but after 9 weeks, scar tissue appears instead. Researchers are, of course, searching for ways to encourage more regeneration in humans.

Do humans have the ability to regenerate limbs?

As of right now, no one has found a way for humans to regenerate in the way that crabs and salamanders do. We may never be able to regenerate a limb like crabs do.
