Using a cube of either programmed metal and wire, or
filtering membrane filled bone, age can be cured: marrow cells are either
dragged into position by a virus, or externally constructed and implanted, the
latter of which is a more likely option. Viral cells then infect the body,
planting chemical markers into the telomeres, which are released as the
telomere shortens to critical level –age inducing level- the membrane detects this: momentarily
hardening against the marker and sending a signal across the membrane to
release captured stem cell genes and other cell division proteins (harvested from
the ambient blood or by the virus, as cells wither, their cell wall unable to
resist the membrane, and while its less needed materials pass through to
degrade within the blood, the required genes remain, sliding into pockets on
the filter to be released by the jarring momentary hardening of the membrane.
By releasing these proteins into the cells nearby (or releasing one of its own
cells to be divided) and the Stem cell genes with them, the cube can create new
cells to replace the worn versions.
One possible path, is to store several stem cells within a
chamber, that is covered by the filter, and exposed when it is jarred, and the
resulting spray of the proper components, can cause this stockpile to divide,
replacing the released stem cell as a new version is formed.
Yet this is far from sufficient to cure age, as this only accounts for blood cell aging, and the hardening of this membrane (similar to the nano fiber water filter) may cause clotting thus:

The membrane is shrouded in electrically sensitive bacteria, which are activated, or rather a shock is released from them when the chemical marker collides with them, causing a muscle action to open the ducts on this new, bony organ. Additonally, a section of the cube breeds Macrophage cells to eliminate the veritable droves of dead cells that will pollute the veins, and thus allowing the Stem cells to replace worn and damaged tissue and age-claimed cells, possibly by using the macrophages to eliminate the cell by rather than a chemical marker detected only by the membrane and virus, it might be a signal similar to that of an apoptic cell, inciting the macrophage to coat this aging cell amid a shroud of antigens, which then commands the white blood cells to consume it, and a stem cell will replace the missing cell. Or, the virus might change the macrophages' stores of antigens with the genes of stem cells, that an aging cell might become a stem cell, yet this might not renew it and it would succumb to the Hayfleck limit all the same.
Nearly any type of hormone or enzyme could be bred within this device, captured within cells which are then slowly multiplied by release of cdc4, then shredded by a virus which captures the hormone and transfers it to another chamber. Thus, should the Human Growth Hormone attempt of the fountain of youth prove successful, one could change it to a self sustainable version, which would easily surpass the dose based version, at nearly any price, for one dose lasting the remainder of eternity, is quite preferable to one each day for the remainder of eternity...
