Regeneration in humans Regeneration in humans Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, which involves closing up the injury site with a scar.

In humans with non-injured tissues, the tissue is naturally regenerated over time; by
