iPSC 衍生的上皮细胞、间充质细胞、内皮细胞和免疫细胞共培养，以模拟肺部健康和疾病中的气道屏障完整性

Overview

This article describes the generation of a complex, multi-cellular airway barrier model composed of induced pluripotent stem cell (iPSC)-derived lung epithelium, mesenchyme, endothelial cells, and macrophages in an air-liquid interface culture. The model aims to better understand human airway remodeling and its response to environmental toxins.

Key Study Components
