A new study has suggested that humans may actually be able to regenerate certain body parts like limbs. Based on extensive analysis of a Mexican salamander called an axolotl that is a “champion of regeneration”, researchers from MDI Biological Laboratory in Bar Harbor, Maine, believe that humans have the “untapped” ability to regrow body parts as well. Incredibly, the axolotl can regrow pretty much any lost body part including their brain, heart, lungs, ovaries, spinal cord, jaws, skin, tail, limbs, etc…
In their research, they focused on how the salamander doesn’t get a scar after an injury or heal in the same manner as mammals and mice. They determined that after an injury, macrophages (immune cells) created scars in a mouse but grew tissue cells in the salamander. The experts believe that the scarring tissue actually blocks the ability for regeneration.
