Novel 3D-printed tissue to keep astronauts healthy during Mars mission

Updated: few hours ago

Berlin, Jul 11 (PTI) A 3D-printed human skin and bone tissue that could help keep astronauts healthy during future Mars missions has been developed by scientists, including those from the European Space Agency (ESA).

"Skin cells can be bioprinted using human blood plasma as a nutrient-rich 'bio-ink' -- which would be easily accessible from the mission crew-members," said Nieves Cubo from University Hospital of Dresden Technical University (TUD) in Germany.

"However, plasma has a highly fluid consistency, making it difficult to work with in altered gravitational conditions.

"We therefore developed a modified recipe by adding methylcellullose and alginate to increase the viscosity of the substrate," Cubo said...
