Restoring the cornea’s support layer to reduce scarring
Regulation of tissue repair and scar formation by the stromal niche
Researchers are trying to restore the cornea’s supporting tissue to help people with corneal scarring from injury, infection, or congenital conditions.

What this research studies
This project looks at the corneal stromal niche — the mechanical and chemical environment that helps the cornea heal without scarring. The team will study how collagen V is re-expressed during healing and how that affects whether corneal cells become normal repair cells or scar-forming myofibroblasts. They will also examine how collagen V influences activation of TGF-β, a key signal that drives excess scar tissue. Work will use lab and animal models to guide ideas for future treatments that could be tried in patients.
Who could benefit from this research
Good fit: Ideal candidates are people with corneal scarring from infection, trauma, or congenital conditions, or patients willing to donate corneal tissue for research at the study site.
Not a fit: People without corneal disease or whose vision loss is due to retinal or optic nerve problems are unlikely to benefit from this cornea-focused work.
Why it matters
Potential benefit: If successful, this work could lead to new medical or surgical approaches that prevent or reduce corneal scarring and lower the need for corneal transplants.
How similar studies have performed: Prior lab and animal studies targeting TGF-β signaling have reduced corneal scarring, but restoring the stromal niche and focusing on collagen V is a newer approach with more limited testing to date.
