Using donated stem cells, bio-ink formed the shape of a specific human cornea in less than 10 minutes; could ensure an unlimited supply of corneas in the future

3D-printing a human cornea (credit: Newcastle University)
Scientists at Newcastle University have created a proof-of-concept process to achieve the first 3D-printed human corneas (the cornea, the outermost layer of the human eye, has an important role in focusing vision).*
Stem cells (human corneal stromal cells) from a healthy donor’s cornea were mixed together with alginate and collagen** to create a “bio-ink” solution. Using a simple low-cost 3D bio-printer, the bio-ink was successfully… read more
