The mechanical properties and forces of the extracellular environment modulate alveolar epithelial cell behavior. To model cancer/fibrosis associated stiffening and dynamic stretch, a biomimetic device was developed that imitates the active forces in the alveolus, while allowing control over the interstitial matrix stiffness. Alveolar epithelial A549 cancer cells were cultured on the devices and their transcriptome was profiled with RNA sequencing.
