3D aging human lung model to study how aging affects epithelial repair

Official title: A 3D aging human ex-vivo lung model to decode the role of mesenchyme in epithelial senescence and repair

Funded at Pennsylvania State University, the · NIH-11439117 · Data updated 2026-11-12

A human-derived, 3D lung model built from stem cells will be aged in the lab to understand why the lung’s repair system slows down as we get older.

Who could benefit from this research

Could help

Ideal candidates would include individuals with aging-related lung changes or healthy donors whose cells are used to build the model (for research, not a patient treatment).

Less likely to help

Direct patient benefit may be limited until later translational steps; the model itself is a research tool.

What this research studies

This project creates a ventilatable, bioprinted 3D alveolar sac from stem cell–derived lung cells to mimic aging lungs. It investigates how aging mesenchymal cells influence epithelial cell function, surfactant production, and tissue mechanics. The goal is to reveal mechanisms behind epithelial senescence and impaired repair in the aging lung using a human-relevant model.

Why it matters

Potential benefit: If successful, this model could help researchers develop therapies to preserve or restore lung repair in older patients.

How similar studies have gone: Similar human-derived 3D lung models have shown promise in replicating alveolar structure and function, but aging-specific interactions are an area of active exploration.
