The printing process lasts 10 minutes.
He hoped that 3D-printed cornea could help people who need cornea transplants worldwide.
Located on the outermost section of the eye, the cornea serves as a protective wall to keep out dust, bacteria, and other tiny items.
About ten million people in the world need transplant of the cornea due to injuries or diseases such as trachoma, which, in particular, can lead to complete blindness.
The researchers first acquired stem cells (human corneal stromal cells) from a healthy donor cornea. Then, the researchers fed that template to a 3D printer, which splashed the bio-ink into a supportive bed of Jello to create the cornea.
A group of researchers from Newcastle University under the leadership of Che Connon (Che Connon) learned using 3D printer to create an artificial cornea, partly consisting of these cells of the cornea - keratocytes.
76ers agree to 3-year extension with Brett Brown
The 57-year-old took over with the 76ers in 2013, and has compiled a 127-283 overall record. The 76ers are expected to make an announcement regarding Brown's extension Wednesday.
Newcastle University researchers have successfully produced artificial corneas using a low-priced 3D bio-printer and a gel formed from human corneal stromal cells, alginate and collagen.
Previously, the same team had used a similar hydrogel to keep stem cells alive for weeks at room temperature.
"Now 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". They scan the patient's eye and the new cornea should be the exact size and shape of the cornea it will replace.
Che Connon, professor of tissue engineering at Newcastle University, praised the medical breakthrough for utilising cheap materials in the process. It protects the eye from bacteria and dust while also helping us to focus an image which eventually travels to the back of the eye, retina. "However, what we have shown is that it is feasible to print corneas using coordinates taken from a patient eye and that this approach has potential to combat the world wide shortage", he said. We have a T-Rex skull, a 300,000 year old hominid jaw, 3D printed mountain ranges, and some Arduino tools to show off along with CR-10 and MOD-t 3D printers. In addition, the authors added cells derived from tissues of human cornea. It's possible to transplant a cornea and restore sight, but there's a major shortage of them.
