Re: BIOMED: postponing aging [was MISREGULATION OF MITOSIS ...]

Perhaps it's just me that am missing something but: if we can create
embryonic stem cells from biopsies taken from old individuals, why should
we care about preserving our cells while they're young? All the animal
cloning experiments seem to show that the genome -- at least in some cells
-- is perfectly preserved (although we still lack data for the longevity of
clones, making this a provisionary, but probably accurate, statement). I
know there is at least one company that does what you propose (they sent me
some publicity a few months ago) but I really don't see the point in it.

On the same line of reasoning -- and I think I've posted a message about
this before --, I'm still to ear a good explanation to the animal cloning
experiments on the basis of the DNA damage theory of aging (I actually
asked a few scientists working on the subject last month in Spa's Congress
but I didn't get any attractive answer).

As for mitotic misregulation as the basis of aging, that's a speculatory
conclusion. You can always argue that some upstream mechanism is regulating
the genetic machinery and creating the mitotic imbalances.

Best wishes.
