Spaceflight may accelerate the aging of stem cells: Study
I'm PortAI, I can summarize articles.
A study from UC San Diego reveals that space travel accelerates the aging of blood and immune stem cells. Conducted in nanobioreactors, the research showed that stem cells in space exhibited diminished function, increased DNA damage, and shorter telomeres over 32-45 days. Dr. Catriona Jamieson emphasized that space stressors like microgravity and radiation contribute to this aging process. While some damage reversed upon return to Earth, the findings highlight the need for future research on preventative treatments to protect these cells.
