Aging cells?

Question

if its the replication of cells and the mistakes on replication that causes aging would you theoretically be able to freeze cells and store them for 40 years and reintroduce them to take over the job of the old cells hence turning back the biological clock. could it ever be used too biuld new doner parts from there own frozen cells taken earlier in life.

Answer 1

i think it might be possible if you were able to preserve those cells in a healthy metabolic state. That's what is being done with cells from the umbilical chords of babies.

and also, there are new discoveries coming up that show that the mitochondria in your cells may also contribute to cells aging. There is a new drug being tested that neutralizes the effects of a certain chemical (can't remember the name)that is produced by mitochondria. A recent study has shown that without or with less of this chemical, rats are able to live up to 40% longer, and healthier. This drug isn't in the clinical trial phase yet, but the researcher who discovered it has been taking the drug for a year now! we'll see how that goes i guess.

Answer 2

I'm not sure how the reintegration of those cells would work and you'd have to pretty much replace entire organs which you can't really spare in the first place.  There's also a matter of how much damage would be done to the tissue during freezing and thawing.  I would imagine that if that were plausible they would just be able to freeze donor organs and thaw them as they needed them.  In the matter of mitochondria mentioned above, one of the factors they release is cytochrome c potentially as a result of mutations in their DNA, leading to cell death. That's still just a theory though.
