While scientists are still working to understand the effects an extended trip to space can have on the human body, research in recent years has suggested that astronauts may experience some pretty dramatic changes on both the physiological and psychological levels. In the latest study led by a team at University of California San Diego, researchers found signs of accelerated aging in human stem cells that spent roughly a month in space. The research focused on hematopoietic stem and progenitor cells (HSPCs), which are crucial in the formation of blood and immune cells. Stem cells were sent to the International Space Station for stays of 32-45 days using specially developed nanobioreactors to monitor them. Another set remained on Earth at the Kennedy Space Center. The cells that went to th [...]
