Regenerating Medicine

Regenerative medicine is the branch of medicine that develops methods to regrow, repair, or replace damaged or diseased cells, organs, or tissues. Regenerative medicine includes the generation and use of therapeutic stem cells, tissue engineering, and the production of artificial organs.

Though it may sound like science fiction, doctors are already producing made-to-order body parts. To get started, doctors scrape cells off the body part in a question and grow them in a petri dish. In time, the body part grows strong enough that it can be implanted in the patient.
