“We can’t reverse time, and time has an effect on any biological organism. The question is how do you respond to the ravages of time. As we talk about these organisms that seem to get through their lives to a grand old age and somehow manage to resist all of the normal degenerative effects of running your engine for many years, it occurs to me that we will be able to be healthier for longer and in some ways, that’s what we all want. That’s really the promise of regenerative medicine.”
