Researcher explores replacing parts of brain with cloned brain tissue to beat aging

A U.S. government researcher is investigating a radical new anti-aging approach: replacing aging parts of the human brain with cloned tissue.

Jean Hébert, a biologist with the Advanced Projects Agency for Health (ARPA-H), is working on "functional brain tissue replacement" as a potential solution to cognitive aging. Hébert’s groundbreaking research involves progressively replacing aging brain tissue with lab-grown cells, aiming to help the brain adapt and preserve memory and identity.

Hébert has already conducted preliminary studies using mice, injecting them with embryonic cells to replace portions of their brains. His bold work, backed by a $110 million funding request from ARPA-H, could open the door to reversing brain aging, although it’s still in its early stages.
