Lab-grown models of how aging and sex affect aortic valve narrowing

Engineered models of age-related biochemical, biophysical, and hormonal changes to elucidate mechanisms of aortic valve disease onset

NIH-funded research University of Colorado Denver · NIH-11249117

What this research studies

Researchers will create engineered tissue models that reproduce age-related biochemical, mechanical, and hormonal changes seen in older aortic valves. The team will include male and female features to study sex-specific differences in how the valve changes. They will compare effects of aged cells versus aged environments and incorporate flow conditions that mimic valve blood flow. The goal is to find early mechanisms that trigger aortic valve narrowing so future therapies can target them.

Who could benefit from this research

Good fit: People most relevant to this work are older adults (especially those 65 and over) and men who are at higher risk for aortic valve narrowing.

Not a fit: Younger people without valve disease or those seeking immediate treatment options would be unlikely to benefit directly from this lab-based work.

Why it matters

Potential benefit: If successful, this work could reveal biological targets to prevent or slow aortic valve narrowing and reduce the need for surgical valve replacement.

How similar studies have performed: Previous studies have modeled valve mechanics and cell behavior, but combining age-related biochemical, biophysical, and hormonal features with sex differences in engineered in vitro models is largely new.
