Alveolar stem‑cell plasticity in lung repair — a research article revealing how alveolar cells cross into airways and aid bronchiolar regeneration.
Key Takeaways
- AT2 cells migrate from the alveoli into injured bronchioles and become club and ciliated cells.
- Immune cell–derived SPP1 and AT2 integrin ITGB1 direct AT2 cell migration toward bronchiolar injury.
- Notch activation from resident ciliated cells drives migrated AT2 cells to transdifferentiate into club cells.
