Banking cells for the purpose of use later in regenerative medicine is supremely pointless. It is a hedge against technological development in cell reprogramming and repair - technological development that is progressing at a revolutionary pace right now, and that will soon enough enable old cells to be restored to youthful configurations. Merely reprogramming cell samples into induced pluripotent stem cells has already been shown to do some of that.

Let us say for the sake of argument, however, that the hedge turns out to be worthwhile, and the exceedingly unlikely course of biotechnology not progressing much past where it is now over the next 20 years takes place. Woe. But then having those banked cells is basically useless because there is very little of worth you can do with them. All of the potential cell therapy applications that might be rolled out today are marginal for someone at very late age.

So cell banking for future use in cell therapies is basically a business that is only useful to its customers if the biotechnology of cellular control both fails to advance and advances spectacularly.
