| Outline of Final Research Achievements |
The purpose of this research is to establish an in vitro model of the human cornea for studying the pre-clinical efficacy and toxicity of ophthalmic drugs. To achieve this, we have: (1) Employed microfluidic technology to construct a human corneal epithelium model that can be subjected to eye blinking-like stimuli.(2) Successfully generated functional corneal epithelial cells from human iPS cells. (3) Used untargeted metabolomics analysis to test the spatiotemporal evaluation of nutrient and metabolite transport and secretion in the human cornea on a chip.

| Academic Significance and Societal Importance of the Research Achievements |
The development of a human cornea model that replicates eye-like blinking can enhance the prediction of ophthalmic drug safety and efficacy. Current preclinical models lack accuracy in this regard. This advancement enables the in vitro reproduction and study of the human cornea.
