Can Regenerative Medicine Defeat Aging?

Here biomedical gerontologist Aubrey de Grey defines "regenerative medicine" somewhat more broadly than just stem cell therapies and enhanced healing: "The human body is, ultimately, a machine - an astronomically complex machine, of whose workings we remain pitifully ignorant - but still a machine. Like any machine, it accumulates 'damage' as a side-effect of its normal operation: molecular and cellular changes that occur throughout life are initially harmless, but eventually (when too abundant) increasingly impede the normal operation of the machine and eventually cause it to fail altogether. ... The relevance of nearly all biogerontology research to combating aging is restricted to the potential for slowing down the accumulation of molecular and cellular damage that eventually leads to age-related ill-health. Meanwhile, regenerative medicine has been progressing rapidly and is nearing clinical applicability to a wide range of specific conditions. My view is that we are approaching the point where regenerative medicine can be used against aging. This would entail not retarding but actually reversing the accumulation of damage. If successful, this would obviously be a far more valuable technology than mere slowing of aging. However, in order to be successful it must be comprehensive, and some aspects of aging may seem impossible to address in this way. In fact, however, it seems that all types of molecular and cellular damage which contribute to age-related ill-health are realistic targets of regenerative interventions."
