Skin and corneal dryness stress protection study

Study Overview

Skin and eyeballs are tissues constantly exposed to dryness stress, but epidermal keratinocytes in skin and corneal cells in eyeballs are the outermost tissues, and they protect the tissue from internal dryness by forming strong intercellular bonds (tight junctions). Therefore, the state of tight junctions is an important indicator for evaluating the tissue’s protective function against dryness.

In this study, we will stain occludin, one of the key proteins that form tight junctions, to evaluate the state of tight junctions in cells after exposure to dryness stress. This will enable us to verify whether the test substance is effective in improving dry skin and dry eye.
