The promise of regenerative medicine to revolutionize medical care for a wide variety of diseases is great. Therapies using blood stem cells and bone marrow transplants for treating certain blood diseases have been developed over the last three decades and are in widespread clinical use.
Yet most other potential applications using stem cells and novel regenerative medicine approaches are early in development. The basic biology of tissue regeneration remains poorly understood and is the subject of intense scientific investigation. Realizing the promise of regenerative medicine as these new therapies are pioneered will take decades. For a few applications, early clinical trials are emerging at the University of Wisconsin and around the world.
