Medical Definition of regenerative medicine
: a branch of medicine concerned with developing treatments that replace injured or diseased tissue with new growths of tissue ◆Regenerative medicine treatments may involve stimulating tissue regeneration at the site of injury or transplanting cells (especially stem cells), tissues, and organs made or grown outside the body. Companies are trying to harness the [stem] cells to rebuild hearts, bone, blood and other tissues, part of a field coming to be called regenerative medicine.—Andrew Pollack, The New York Times, 30 May 2000
