Acorn Cryotech, a Toronto startup, does this. They store cells from hair follicles, but I think they're still in the process of launching, so you can only get your cells collected at their office or at certain events attended by their staff. It's $300 CAD upfront and $16/month (i.e. $192/year) thereafter.
Is this a good idea?
I don't know a ton about longevity research (i.e. I've read the Longevity FAQ, the LRI blog, and a few papers here and there), so I wouldn't give my opinion here too much weight. Reviewing the FAQ linked above, it seems reasonable to believe that:
- a transfusion of blood generated from younger cells would do more good than a transfusion from older cells
- organs generated from younger cells might last longer, because it would take longer for their cells to become senescent
I expect further developments along these lines. I don't know whether we'll discover methods to reverse cellular aging before we develop practical cell-based longevity therapies.
I'm not going to cryopreserve my stem cells any time soon; I'd prefer to spend my money on charity and freezing my gametes. I think someone with a different budget or different values could reasonably reach a different conclusion.
