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". This field holds the promise of engineering damaged tissues and organs via stimulating the body's own repair mechanisms to functionally heal previously irreparable tissues or organs.
A landmark study published today (Sept 12) in Nature shows that reprogramming of adult cells that behave like stem cells can be achieved right inside the body (in vivo). Till now, reprogramming of adult cells has been achieved only in labs (in vitro).
