New stem cell bio-ink allows 3D printing of a living tissue

Scientists at the University of Bristol have developed a new kind of bio-ink. This discovery could allow the production of complex tissues for surgical implants. The new stem cell-containing bio-ink allows 3D printing of a living tissue, also known as bioprinting.
This bio-ink contains two different polymer-based components. One, extracted from seaweed, is a natural polymer. The other, used in the medical industry, is a sacrificial synthetic polymer. Both of these had a big role to play in the development of the bio-ink. The synthetic polymer alters the bio-ink from a liquid to a solid when its temperature rises. When cell nutrients are added the seaweed polymer provides structural support.
