New lung blood-vessel stem cells that help repair lungs after ARDS
Novel intrinsic endothelial stem cells responsible for lung endothelial regeneration and vascular repair in ARDS
The project focuses on a rare lung blood-vessel cell that helps rebuild the lung lining after severe infection-related breathing failure in adults.

What this research studies
If you've had ARDS, researchers are studying a rare lung blood-vessel cell called UC+ endothelial stem cells that may rebuild damaged lung vessels after sepsis. They will examine these cells' genes and growth behavior using lab models and samples from patients and animals, and will remove them in animals to see how healing changes. The team will compare these cells to other known vascular progenitors to confirm they are unique. The goal is to learn whether protecting or boosting these cells could help lungs recover after severe injury.
Who could benefit from this research
Good fit: Ideal participants would be adults with sepsis-related ARDS or adults able to donate lung tissue or blood samples for research.
Not a fit: Children and people without sepsis-related ARDS are unlikely to directly benefit from this specific research.
Why it matters
Potential benefit: If successful, this work could point to ways to restore damaged lung blood vessels and improve recovery and survival after ARDS.
How similar studies have performed: Prior animal and patient studies show endothelial cells can aid lung repair, but identification of this specific UC+ stem cell population is novel and not yet tested in treatments.
