Who could benefit from this research

Could help

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.

Less likely to help

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.

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.

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 gone: 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.

  • Understanding how uterine scars affect placenta growth

    This study is looking into how past surgeries, like C-sections, can cause the placenta to grow too deeply into the uterus, and it aims to find ways to prevent or treat this condition by understanding the changes in the uterus that happen because of scar tissue.
