| 研究実績の概要 |
The applicant has finalized the protocol for the generation of human corneal epithelial cells from human pluripotent stem cells (hPSCs) using a simplified small molecule-based corneal induction method (SSM-CI). The applicant has also conducted RNA sequencing (RNA-seq) to compare the generated cells with human primary corneal epithelial cells (hPCEpCs). RNA-seq analysis indicated the faithful differentiation of hPSCs into corneal epithelial cells, with significant upregulation of corneal markers. Moreover, the applicant has integrated the corneal epithelium barrier on a chip with untargeted metabolomic analysis for the spatiotemporal analysis of metabolites; and 104 metabolites were annotated such as glutathione and uric acid.

3: やや遅れている
理由
Due to the COVID-19 situation, the initiation of experiments involving hPSCs were delayed until further acquirement for ethical approvals and the purchase of research materials.
|
| 今後の研究の推進方策 |
1-The characterization of hPSC-derived corneal epithelial cells in microfluidic devices.
2-The evaluation of the spatiotemporal toxicity of ophthalmic drugs in the corneal epithelium barrier on a chip.
3-The employment of the applicant's previous reported publication for the observation of molecules secretion and transportation across the corneal epithelial barrier under drugs treatment.
|
| 次年度使用額が生じた理由 |
Due to the COVID-19 pandemic situation, the applicant could not use the budget for attending international or domestic meetings. Therefore, the applicant is expecting to use the budget in the current fiscal year for the above-mentioned purposes as well as for publishing the results in the form of research papers.
