Regen

"Regen" refers to the concept of regeneration, which can be applied in various contexts such as biology, medicine, and environmental science. In biology, regeneration is the process by which organisms replace or restore lost or damaged tissues, organs, or limbs. For example, some lizards can regrow their tails, and starfish can regenerate entire arms. In medicine, regenerative medicine involves techniques like stem cell therapy and tissue engineering to repair or replace damaged tissues and organs in humans. Environmentally, regeneration can refer to the renewal and restoration of ecosystems and natural resources, promoting sustainability and biodiversity.
