Scientists 3D-Print Human Skin and Bone For Mars Astronauts
Scientists from the University Hospital of Dresden Technical University in Germany have successfully bio-printed skin and bone samples upside down to help determine if the method could be used in a low-gravity environment. CNET reports: The skin sample was printed using human blood plasma as a "bio ink." The researchers added plant and algae-based materials to increase the viscosity so it wouldn't just fly everywhere in low gravity. "Producing the bone sample involved printing human stem cells with a similar bio-ink composition, with the addition of a calcium phosphate bone cement as a structure-supporting material, which is subsequently absorbed during the growth phase," said Nieves Cubo, a bioprinting specialist at the university. These samples are just the first steps for the ESA's ambitious 3D bio-printing project, which is investigating what it would take to equip astronauts with medical and surgical facilities to help them survive and treat injuries on long spaceflights and on Mars.Read more of this story at Slashdot.
