First 3D-printed human corneas can aid transplants
The Quintlondon, May 30 In a first, British scientists have 3D printed human corneas that could cut down shortage of eye donors available for transplant. In the research, researchers from Britain's Newcastle University, mixed stem cells from a healthy donor cornea with alginate and collagen to create a solution that could be printed or a "bio-ink". "Our unique gel -- a combination of alginate and collagen -- keeps the stem cells alive whilst producing a material which is stiff enough to hold its shape but soft enough to be squeezed out the nozzle of a 3D printer," said lead author Che Connon, a professor at the varisty. ".we have a ready to use bio-ink containing stem cells allowing users to start printing tissues without having to worry about growing the cells separately," Connon added.
