Human stem cells faster in space, finding studies

While scientists are still working on understanding affects an extended trip to the space may have on a human body, research in recent years it suggested Astronauts can experience some pretty dramatic changes both on physiological and psychological level. No later than study on the forefront of University of California San DiegoThe researchers found signs of accelerated aging in human stem cells that were spent in space for about a month.

The research focused on hematopoietic stems and descendants (HSPC), which are crucial in the formation of blood and immune cells. The stem cells were sent to the International Space Station for a stay of 32-45 days using specially developed nanobireactors to monitor them. Another set remained on Earth in the Kennedy Space Center. The cells that went to the ISS showed a multitude of changes, including reduced self-renewal skills, greater sensitivity to DNA damage and inflammation in mitochondria. However, the damage seems to be not permanent. The team notes that changes at least turn partially turned when cells were removed from the space environment.

“The space is the ultimate stress test for the human body,” he said in the statement in the statement. “These findings are critically important because they are stressors of space – such as micrograss and cosmic galactic radiation. Understanding these changes not only inform the astronauts during long-term missions, but we also help to model on the land.”
