The promise of a regenerative medicine — the regrowth of lost limbs and organs, new hope for patients with Alzheimer's or multiple sclerosis, the "cellular fountain of youth" — sounds like science fiction, but it's real and on the cutting edge of medicine. Veteran medical journalist Karen van Kamped looks at this new technology through the stories of the scientists who are creating it and the ethical and legal questions with which they must deal. Many companies and universities in Canada are at the forefront of cellular research, and this fascinating book shows that the next frontier of medicine is unfolding around us.
