JAXA astronaut Kimiya Yui treats bioprinted liver tissues inside a portable glovebag

iss073e0606897 (Sept. 5, 2025) --- JAXA (Japan Aerospace Exploration Agency) astronaut and Expedition 73 Flight Engineer Kimiya Yui treats bioprinted liver tissues in a portable glovebag inside the International Space Station's Harmony module. The samples will be placed inside an artificial gravity-generating research device to help researchers understand how microgravity affects the formation of blood vessels in engineered tissues. Result may lead to advanced treatments protecting astronauts on long-duration spaceflights and improve bioprinting techniques for patient therapies on Earth.
