Now, a team at Newcastle University in the UK has succeeded in 3D-printing a human cornea equivalent (2). The proof-of-concept study, led by Che Connon, Professor of Tissue Engineering, mixed stem cells from a healthy donor cornea with alginate and collagen to create a “bio-ink”, which was 3D printed in concentric circles to form the shape of a cornea in less than 10 minutes. We spoke with Connon to find out more...
