| Outline of Final Research Achievements |
Applying micro/nanotechnologies including microfluidic devices and polymeric nanosheets to the ophthalmologic field, an organ on a chip that mimics the ocular fundus was developed. Also, based on findings on cell functions at the tissue level obtained by the analysis of the organ on a chip, cell delivery therapy was investigated. In order to recapitulate the ocular fundus functions, neural supporting cells such as retinal pigment epithelial (RPE) cells were cultured within a three-dimensional microfluidic device, and cell responses at the tissue level to changes in the microenvironment were analyzed. Also, the obtained results were applied to control the tissue functions of RPE cells cultured on the polymeric nanosheets, which was extended to a method to deliver an RPE sheet into the subretinal space.
