| Outline of Final Research Achievements |
Vitamin D plays a lot of roles not only on bones but also on many organs including several epithelial tissues. The main aim of this study was to evaluate the roles of vitamin D on the epithelial tissues on ocular surface.
First, we developed an method to culture mouse corneal epithelial cells to make stratified 3D tissue mimicking human corneal epithelium, which has microvilli and basement membrane. Then, we checked the effects of active form of vitamin D on it. Although, the active form of vitamin D suppressed cell proliferation, in the recovery from partial peeling by scratching, re-epithelializing cells showed different expression patterns in cell adhesion molecules and intracellular F-actin, suggesting that vitamin D modifies cell adhesions and movements of corneal epithelial cells.
