US EditionUCSD takes detailed look at how space flight accelerates aging
UC San Diego researchers observed accelerated aging signs in astronauts' blood stem cells during 30-45 day space missions, with partial reversal after returning to Earth, aiding aging and disease research.
- This month, University of California, San Diego researchers reported that space flight accelerates aging in blood and immune system stem cells, tracking these changes in real time aboard the International Space Station; findings appeared in the journal Cell Stem Cell.
- Research has linked microgravity and cosmic galactic radiation during spaceflight to accelerated molecular aging in blood stem cells, Dr. Catriona Jamieson said, aiding astronaut health and human aging research.
- After 32 to 45 days in orbit, blood-forming hematopoietic stem and progenitor cells showed aging hallmarks, losing regenerative ability and gaining DNA damage, tracked by automated AI-driven imaging on four SpaceX supply missions.
- Returned space-exposed cells showed some damage reversed in a healthy environment, prompting UC San Diego researchers to continue studying astronauts and explore applications for aging and cancer research on Earth.
- Nanobioreactors and AI-powered imaging tools enabled UCSD and Space Tango, a for-profit space research company, to study stem cell resilience during the SpaceX resupply mission that launched last month, building on NASA's Twins Study.

Study finds spaceflight accelerates aging of human blood-forming stem cells
New research has identified yet another way that spaceflight tampers with the human body. A study involving samples flown on four SpaceX resupply missions to the International Space Station has revealed that space travel accelerates the aging of blood-forming stem cells crucial for blood and immune system health.
UCSD takes detailed look at how space flight accelerates aging
The famous “Earthrise” photo taken by astronaut Bill Anders aboard Apollo 8 in 1968. (File photo courtesy NASA) New research in understanding aging and disease – and how to potentially reverse it – is both on the earth and in the stars. University of California, San Diego researchers working out of the Sanford Stem Cell Institute have found that space flight advances aging in cells. The study sent human hematopoietic stem and progenitor cells o…

By Will Dunham WASHINGTON (Reuters) -New research has identified yet another way that spaceflight tampers with the human body. A study involving samples flown on four SpaceX resupply missions to the International Space Station has revealed that space travel accelerates the aging of blood-forming stem cells crucial for blood and immune system health. The scientists in the NASA-funded study conducted real-time monitoring of stem cells from the bon…
