Everyone is born with a genetic code, or DNA sequence. This genetic code stays mostly the same throughout your life. However, your epigenetic code is subject to change throughout your life. This change can come from a number of factors such as age, disease, and environmental stimuli including nutrition and lifestyle. However scientists have recently found a way to reverse a person’s epigenetic code, potentially unlocking the ability to cure hundreds of diseases and extend life by decades.

This “cellular rejuvenation” is one of the newest and most promising developments in longevity research. This research kicked off in 1993 when a scientist at the University of California, San Francisco, proved that tweaking a single roundworm gene can double the roundworm’s lifespan. Since then, scientists have learned how to trigger rejuvenation in a lab setting. From curing diseased mice, to healing the failing kidneys of rats, and even reversing the cells of a 90 year old man in a petri dish, these scientists have made impressive progress in their research. In fact, in March scientists began their first safety trials on humans by attempting to reverse disease in the eyes and cure glaucoma.

This technology is advancing so rapidly that it is no longer a question of whether this therapy would work to reverse human epigenetics, but rather to what extent it could be used. Epigenetic change is the leading cause of aging and age related health decline in mammals. Now that scientists have found a method to reverse this epigenetic change, the human lifespan could be extended greatly. The therapy could also mitigate or delay diseases associated with aging. On top of all of this, cellular rejuvenation could improve the cognitive function of those treated, slowing or reversing age-related cognitive decline.

To some, this therapy might seem like something out of a science fiction book. However, to the scientists working on this groundbreaking research, it is very real. Not only this, but it’s not too far in the future.
