Study: Travel for space accelerates the aging of the stem cells needed for blood health

A recent study found that traveling to space accelerates the aging of the blood -forming cells needed for blood and immune systems health. A study of samples transported on 4 missions from SpaceX to the International Space Station showed that space feed accelerates the aging of stem cells. In the study funded by the US Aviation and Spatial Administration “NASA” NASA, the stem cells of the bone marrow donors took to follow the changes that took place during the missions that lasted between 30 and 45 days in December 2021 and July 2022, November 2022 and March 2023. It appears that the cells sent to space have lost part of their ability to form healthy new cells, and that they have become more vulnerable to DNA damage, proving that it ages faster in the ends of chromosomes, which resemble the wrapped wires and genetic information from one cell to another. The researchers attributed these changes to semi -numbess and increased exposure to radiation during spacecraft. Stem cells and stem cells are cells in the body that can develop in different types of cells. The cells that have undergone the study, which are called the stem cells that make up blood and salafi cells, produce all blood cells in the bone marrow, which are the soft tissues in the bones, which include red blood cells containing oxygen, white blood cells that represent part of the immune system and combat infection, and roots that use blood clot. The functional imbalance in these cells can reduce the ability of the body to restore damaged tissues, reduce the monitoring of the immune system to monitor cancer, fight the ability to fight infection and reduce age. The researchers said that the cells are excessive activity during spacecraft, leading to the depletion of their reserves and their ability to rest and recover, a function that can renew the stem cells over time. The cells also have signs of inflammation and fatigue in the mitochondria (nematode grains), which generate energy in the cell, and have begun to activate the hidden parts of the genome that remains a quiet habit of maintaining stability. Last week, the researchers in the study found differences in the way the stem cells respond to traveling to space, depending on the donor. Increasing the health risks, the leader of the study team, dr. Katriona Gimison, a professor at the University of California of California, and the director of the Sanford Institute of Voice cells at the university: “The capacity of stem cells has diminished, but with some bone marrow donors, indicating that the factors of the ability to become aged are active in the sturdy person. Planet offers a protective shield of cosmic rays, astronauts are exposed to high -energy radiation that permeates the universe. Jimson explained that understanding the changes in the blood -forming stem cells can help the ways to protect astronauts from these consequences during long -term missions. enterprise has been introduced.
