Regenerative medicine is a branch of translational research in tissue engineering and molecular biology which deals with the "process of replacing, engineering or regenerating human cells, tissues or organs to restore or establish normal function". It includes engineering damaged tissues and organs by stimulating the body's own repair mechanisms to functionally heal previously irreparable tissues or organs. In case when the body cannot heal itself, tissues and organs can be grown in laboratory and implant the same. 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. In fact, there is no age limit for the use of Regenerative Medicine. A Regenerative Medicine is an organ, tissue or a group of cells removed from one person (the donor) and surgically transplanted into another person (the recipient or host) or moved from one site to another site in the same person. When injured or invaded by disease, our bodies have the innate response to heal and defend. Regenerative Medicine is working to restore structure and function of damaged tissues and organs. It is also working to create solutions for organs that become permanently damaged. The tools used to realize these outcomes are tissue engineering and cellular therapies.
