The new stem cell containing bio-ink allows 3D printing of living tissue, known as bio-printing.
The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed and a sacrificial synthetic polymer used in the medical industry, and both had a role to play. The synthetic polymer causes the bio-ink to change from liquid to solid when the temperature is raised, and the seaweed polymer provides structural support when the cell nutrients are introduced.
