Today’s Video of the Day from the European Space Agency shows the first steps of a project which aims to print human tissue to help injured astronauts heal when they are far away in outer space.
Scientists at the University Hospital of Dresden Technical University bio-printed skin samples using human blood plasma as a bio-ink.
“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,” explained bioprinting specialist Nieves Cubo.
The team tested their printing method upside down to investigate whether the technique could be used in a low-gravity environment, and it proved to be successful.
