There are a number of things published at peer reviewed journals that double the rate of healing, ginger extract, curcurmin, as well as goop, a combination of chitosan with alginate. I think it is possible the rate as well as the fidelity of reconstruction could affect longevity.
certainly feeding lab mammals lots of ginger extract as well as curcurmin to see if it affected tissue quality throughout life as well as longevity is of value. I really wonder if better healing affects general tissue morphology as if you imagine "stacking puckered spheres" the number of contacts at each surface receptor as well as the between cytofluid ion concentrations would change a lot with changes to cytogeometry. wound healing histology (images of tissue) change a bunch with the ginger as well as curcurmin chemicals, thus it is possible that drugs that regularize histology could also reduce aging creating greater longevity.
although chitosan (bugs), as well as alginate (algae) are likely rare at wild type mammals I think it might be possible to genetically engineer lab mammals to make twice as much hyalonuric acid, a different goop, as well as more mucoproteins. apparently the superexpression of gooeyness benefits healing, at least at the surface. yet it is possible that throughout tissues modifying the hygroscopicity (water gooeyness) of between cyte fluid as well as cytoplasm could have a beneficial effect on tissue repair
