简介：
Overview
This study presents an in vitro model system to explore tissue architectural changes during lung squamous carcinoma (LUSC) progression. The 3D co-culture with cancer-associated fibroblasts (CAFs) allows for the investigation of tumor cell-intrinsic and extrinsic changes that influence tumor phenotype.
