Limb regeneration remains the stuff of science fiction for humans, but an accidental discovery provides a new window into what it would take for people to grow lost limbs with newtlike flair. Healing powers of this kind were first discovered in 1740, when Abraham Trembley discovered that a green pond animal could regenerate its tentacle-crowned head if it was amputated.

Captain America represents the perfect human being, so one can assume that his healing-factor is not on the level of Wolverine, who can regenerate within seconds. When Lin28a turns on and expresses a protein in the body, it boosts the metabolism, apparently fooling the body into thinking that it is younger and spurring a complex cascade of chemical reactions that generate energy. Gardiner notes that younger people seem better able to heal than older ones. It will turn everyone into a monster except Alice because for some reason she was able to bond with it.
