This means that one donor cornea can help multiple patients.<\/p>\n<p>\u201c\u201cThis builds upon our previous work in which we kept cells alive for weeks at room temperature within a similar hydrogel. 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,\u201d said researcher Che Connon. He built the technology with Dr. Steve Swioklo.<\/p>\n<p>The corneas take ten minutes to print on a cheap 3D printer, a vast improvement on previous efforts. Further, the gel can keep stem cells alive for days, allowing you to print a few corneas over the course of a week.<\/p>\n<p>\u201cThis builds upon our previous work in which we kept cells alive for weeks at room temperature within a similar hydrogel.
