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 the ISS showed a host of changes, including reduced self-renewal abilities, greater susceptibility to DNA damage and inflammation in the mitochondria. However, the damage didn&#8217;t appear to be permanent. The team notes that the changes were at least partially reversed when the cells were removed from the space environment.\u00a0<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 engadget-charcoal\">\u201cSpace is the ultimate stress test for the human body,\u201d Catriona Jamieson, director of the UC San Diego Sanford Stem Cell Institute, said in a statement. \u201cThese findings are critically important because they show that the stressors of space \u2014 like microgravity and cosmic galactic radiation \u2014 can accelerate the molecular aging of blood stem cells. Understanding these changes not only informs how we protect astronauts during long-duration missions but also helps us model human aging and diseases like cancer here on Earth.&#8221;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"While scientists are still working to understand the effects an extended trip to space can have on the&hellip;\n","protected":false},"author":3,"featured_media":210483,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[115460,109329,6756,115459,159,54158,67,132,115458,68],"class_list":{"0":"post-210482","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-dramatic-changes","9":"tag-immune-cells","10":"tag-kennedy-space-center","11":"tag-progenitor-cells","12":"tag-science","13":"tag-stem-cells","14":"tag-united-states","15":"tag-unitedstates","16":"tag-university-of-california-san-diego","17":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115169329312785846","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/210482","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=210482"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/210482\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/210483"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=210482"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=210482"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=210482"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
