The SHOCKING Science On Extending & Reversing LIFESPAN | George Church

Cell Reprogramming

George Church discusses the potential of reprogramming cells to maintain or return to a youthful state. He explains that addressing all the hallmarks of aging is crucial, as missing even one can lead to failure. Church's team focuses on restoring a younger internal state by examining proteins and nucleic acids in cells, which can lead to cells behaving youthfully 1.

We can take 80-year-old cells from an 80-year-old person and reprogram them to behave as if they were embryonic.

This reprogramming, however, is not yet clinically applicable, as transforming all cells into embryonic ones would not be feasible for adults 1.

   

Yamanaka Factors

The role of Yamanaka factors in biological reprogramming is explored, highlighting their potential to reverse aging. These transcription factors, discovered by Shinya Yamanaka, can reprogram cells to a younger state, offering a glimpse into future human applications 2. Church notes that while animal trials have shown promise, human clinical trials are still on the horizon, with delivery methods posing a significant challenge 3.

It's not that we don't know how to do it for humans, we might know how to do it for humans, but it's going to take a while to get it into clinical trials.

--- George Church

Church remains optimistic about the potential of gene therapy and Yamanaka factors, suggesting that clinical trials could begin within the next decade 3.
