Cornea Tissue Engineering

A major challenge in corneal tissue engineering and lamellar corneal transplantation is to develop synthetic scaffolds able to simulate the optical and mechanical properties of the native cornea as highly innervated and avascular tissue. The fabricated substrates must be transparent, biodegradable, permeable to gas and liquid, with mechanical properties and fiber alignment similar to native corneal tissue. Therefore, we utilized electrospun fibers with aligned morphology as well as composite hydrogel-based inks with nanofibrils of silk as two approaches to culture the corneal cells. We showed the electrospun fibers are bio- and immunocompatible and supported the viability of human corneal cells without triggering effects in granulocytes and peripheral blood mononuclear cells.
