| Outline of Final Research Achievements |
In this study, we studied basic technology for an extremely similar structure with corneal structure, by using collagen and silk materials which we have studied. Using electrospinning method, we developed epithelium basal membrane similar nanofiber scaffolding. And we tried to develop the transparency improved nanofiber. And we got fundamental data about high intensity Descemet's membrane structure regeneration.
Turning fiber size down to a level of nano, and making the comfortable space between the nanofibers(cell Niche), the light scattering had been minimized, then the transparency was improved. Higher order structures, surface characters, and hardness of the fibers, were strongly affect to the responses of both corneal epithlium and Keratocyte.
