Researchers Successfully Achieve Suspended Animation With Mouse Embryos

"It was completely surprising. We were standing around in the tissue culture room, scratching our heads, and saying 'Wow, what do we make of this?'" An anonymous reader quotes Engadget's report on new research with "huge implications":A team of scientists from the University of California, San Francisco only wanted to slow down mice embryos' cell growth in the lab. Instead, they managed to completely pause their development, putting the blastocysts (very early embryos) in suspended animation for a month. What's more, they found that the process can put stem cells derived from the blastocysts in suspended animation as well, [and] the researchers were able to prove that the embryos can develop normally even after a pause in their growth. Team member Ramalho-Santos from the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research said... "To put it in perspective, mouse pregnancies only last about 20 days, so the 30-day-old 'paused' embryos we were seeing would have been pups approaching weaning already if they'd been allowed to develop normally." The new research could lead to better treatments for damaged organs and even aging, according to the article. (Besides, of course, its science fiction-y implications for long-distance space travel...)
