Regenerative medicine is the process of replacing or regenerating human cells, tissues or organs to restore or establish normal function, and could be one way to extend lifespan through medicine. This field holds the promise of regenerating damaged tissues and organs in the body by replacing damaged tissue and/or by stimulating the body's own repair mechanisms to heal previously irreparable tissues or organs. Regenerative medicine also empowers scientists to grow tissues and organs in the laboratory and safely implant them when the body cannot heal itself.
