Improving immune and scarring responses after large muscle loss

Engineering the Immune and Fibrotic Response in Volumetric Muscle Loss

NIH-funded research University of Oregon · NIH-11146468

This project is looking for ways to reduce scarring and fat buildup so people with major muscle injuries can heal with more muscle and better function.

What this research studies

If you had a large muscle injury, this team is trying to understand why the damaged area fills with scar and fat instead of new muscle. They focus on key cells called fibro-adipogenic progenitors and muscle stem cells and on the immune signals that drive poor healing. The work uses lab and animal models to test materials and biological approaches that could shift the immune and fibrotic responses. The goal is to develop treatments that could eventually be tested in patients with traumatic volumetric muscle loss.

Who could benefit from this research

Good fit: People who have experienced large, full-thickness muscle loss from trauma or surgery and are seeking new regenerative treatment options.

Not a fit: People with minor muscle strains, general age-related muscle loss, or unrelated systemic muscle diseases may not benefit from this work.

Why it matters

Potential benefit: Could lead to therapies that limit scarring and fatty replacement and restore muscle structure and function after severe muscle injuries.

How similar studies have performed: Preclinical studies have shown that targeting fibro-adipogenic progenitors and immune responses can reduce fibrosis in animal models, but human benefit remains unproven.
