A New Bio-Ink for Bioprinting Innovation

University of Bristol researchers say they were able to engineer 3-D printed tissue structures including a full-size tracheal cartilage ring over five weeks. How did they do this? The secret was a special bio-ink formulation, infused with stem cells and created after an arduous trial and error process.

Printing with living cells to create human tissue has been a major medical technology goal, but has been a complex challenge to solve as researchers struggle to get cells to create complex structures. So the British researchers' innovation could prove to be an important development.
