Pulmonary fibrosis, especially when triggered by toxins such as paraquat, is a life-threatening condition driven by inflammation, epithelial-mesenchymal transition (EMT), and invasive cell behavior. To understand and halt this progression, researchers require a physiologically relevant in vitro system that can mimic the extracellular matrix and support accurate migration and invasion studies.

In this study, researchers used VitroGel® Cell Invasion Assay Kit to create a 3D-like ECM environment in vertical invasion assays. This setup allowed them to precisely monitor the impact of naringin, a natural anti-fibrotic flavonoid, on A549 lung epithelial cells under paraquat-induced stress.
With VitroGel® as the invasion barrier, they observed that naringin significantly reduced cell migration and invasion, while also lowering EMT and fibrosis-related markers such as N-cadherin, α-SMA, and TGF-β. It also restored PPARγ expression, a key anti-fibrotic regulator suppressed by paraquat exposure.
These results clearly demonstrate that VitroGel® provided a critical platform to validate the protective effect of naringin, enabling researchers to track cell behavior in a more physiologically relevant setting.
