Researchers at Pohang University of Science and Technology (POSTECH) and Kyungpook National University in South Korea have achieved a major milestone by 3D printing an artificial cornea using a specialized "bioink" made from decellularized corneal stroma and stem cells. This bioprinted tissue is designed to perfectly replicate the intricate lattice pattern of human collagen, ensuring the transparency and flexibility required for the eye to function naturally. By regulating the "shear stress" during the printing process, the team was able to align collagen fibrils in a way that mimics a native human cornea, a feat previously thought impossible with synthetic materials.
