So what you're saying is that the mice that didn't have their genome edited didn't have a drastic life extension? I assume the improvements only occurred in the mice that had their genomes edited to reduce Yamanaka factors because they then artificially replaced the Yamanaka factors?

No. That's not quite what I'm saying. There was no particularly interesting effect of inducing transient expression of the Yamanaka factors on normal mice reported in this paper. It is effectively a negative result that's being reported, as it pertains to wild-type mice.

The paper primarily reports results that pertain to mice with a genetic defect that causes progeria. Mice with this defect have a shorter-than-normal lifespan.

so its more a treatment for progeria than general aging reversal
