简介：
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.
