sometimes they modify tissues (like porcine tissue) to be immunoneutral so they do better at transplantation. taking stem cells from supercentenarians, then making them immunoneutral to other humans, then transplanting them could produce unusually long lived beneficial stem cyte effects, possibly as a new longevity technology

there is another version of this, where using a naturally dead giant cetacen, like a blue whale (some of which have been published as having muticentury longevity) do tissue culture on the cetacean tissue, modify it to be immunoneutral (something like changing external liposachharides) then using those stem cells as multicentruy lifespan new human repair tissues

Wouldn't there be problems with telomere length ? lack thereof.

Giant tortoises live a very long time - many centuries.

Then again, they live very dull lives. Maybe they have much shorter real lifespans, but they just seem very, very long from the tortoise's point of view.

So the obvious thing is to identify humans with significant amounts of tortoise DNA and extract it. Slow moving, cold-blooded, ponderous, low intelligence and with a thick protective shell ... the upper ranks of the civil service would be a rich hunting ground.
