Old cells, made young again, in under a week. Harvard pulled it off with chemicals alone.
A team at Harvard Medical School led by David Sinclair identified six chemical cocktails that reset aging human cells to a younger state.
Until now, rewinding a cell’s age took gene therapy, which is costly and hard to roll out widely. These cocktails skipped the genetic route entirely. The cells also kept their identity, so they got younger without turning into something else.
The findings were published in the journal Aging in July 2023.
Sinclair says the best science could do before was slow aging. Now he believes we can reverse it, and maybe one day with a single pill.
