Stem cell brain implants could 'slow ageing and extend life', study shows

Researchers hope to launch human trials as breakthrough shows hypothalamus controls ageing, with treated mice remaining fitter and living 10-15% longer

Scientists have slowed down the ageing process by implanting stem cells into the brains of animals, raising hopes for new strategies to combat age-related diseases and extend the human lifespan.

Implants of stem cells that make fresh neurons in the brain were found to put the brakes on ageing in older mice, keeping them more physically and mentally fit for months, and extending their lives by 10-15% compared to untreated animals.
