Researchers at Newcastle University are 3D printing corneas utilizing stem cells. The process involves mixing stem cells in a bio-gel which is derived from seaweed and collagen that allows these stem cells to be cultured and printed easily and efficiently into fully functioning corneas. The cornea plays an important role in focusing light that enters the eye. Technically, blindness caused by corneal damage is easily reversible with a corneal transplant. However, there is a vast shortage of donor corneas due to general organ and tissue donation shortages. In addition, there is also a significant risk of rejection - as is the case with any donated tissue.
This revolutionary printing method could help millions with corneal blindness regain their vision. “This 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,” comments Che Connon, Professor of Tissue Engineering at Newcastle University. Additionally, the culturing protocol that differentiates the stem cells into corneal tissue could be applied to growing other types of organs and accelerate other stem cell treatments.
Advances in stem cell based regenerative treatments are creating more effective treatment options for patients suffering from a wide variety of disease, trauma and injury. To learn more about stem cells, and how families can bank their own valuable stem cells by recovering the very powerful dental pulp stem cells during routine dental procedures; such as wisdom teeth extractions or the during the loss of baby teeth, visit StemSave or call 877-783-6728 (877-StemSave) today.
