Blood storage for autologous transfusion has apparently already been a thing for a while[1] and has been indicated to be effective in animal experiments[2], but as far as I can tell, no provider is willing to store it for more than about 20 years (and what is stored may not in fact contain stem cells, but rather only something that spurs the existing ones into activity). My general impression is that the medical community's moral gut reaction is unfavourable towards the idea.
