Researchers from Newcastle University in the UK has come up with the first ever 3D-printed human corneas that allow patients as well as healthcare professionals to access web-based emergency clinical management information. Outlined in the eye research, the process mixes stem cells from a healthy donor cornea with alginate to create a bio-ink that is extruded from a low-cost 3D bio-printer in concentric circles to form a human cornea.
Moreover, the university included the stem cells were appeared to develop, enabling users to begin printing tissues without growing the cells independently. The university included that this method could handle a critical lack of corneas accessible to transplant and may profit a great many individuals overall requiring the corneal medical procedure to avert blindness.
Professor of Tissue Engineering at the university who led the research, Che Connon said, “Many teams across the world have been chasing the ideal bio-ink to make this process feasible.” Further, Connon added, “Our unique gel 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.”
Newcastle University researcher demonstrated the ability to use data from an eye scan to print a cornea that matches a patient’s specifications. The 3S-printed corneas will undergo further testing; it means it could be several years before they’re used for transplants.
The 3D printing methods are significantly being used in the field of prosthetics and healthcare. Moreover, the United States researchers found the new method to develop soft robots with embedded touch sensing.
