Age Reversal Breakthrough: Harvard/MIT Discovery Could Enable Whole-Body Rejuvenation::In a pioneering study, researchers from Harvard Medical School, University of Maine, and MIT have introduced a chemical method for reversing cellular aging. This revolutionary approach offers a potential alternative to gene therapy for age reversal. The findings could transform treatments for age-re
The full journal article says “in vivo” not “in vitro”. They have already successfully regenerated mice which are organisms biologically similar to humans.
Edit
I was wrong about this. The journal article does only talk about results obtained “in vitro” but mentions other studies that have successfully reversed cellular ageing “in vivo”.
So in this study the results were only in vitro but other studies have successfully reversed cellular ageing in vivo.
