Enhanced application potential of alveolar organoids through epithelial and niche cell interactions

Recent studies have focused on understand lung repair mechanisms, which are critical for treating respiratory diseases. In this study, we develop alveolar organoids to investigate the complex interactions between alveolar epithelial cells, niche fibroblasts and macrophages, which are essential for lung development, maintenance and repair, especially under physiological injury. Our results suggest that alveolar organoids may be a model for epithelial cell regeneration and the inflammatory response in lung tissue. Alveolar organoid studies can also serve as models for various lung injuries and demonstrate mechanisms in the injured human lung.
