Researchers developed a method to differentiate human pluripotent stem cells (hPSCs) into club cells, a specialized airway epithelial cell type involved in maintaining lung integrity and regulating inflammation. Using single-cell transcriptomic analyses, they identified an unexpected differentiation pathway in which hPSC-derived club cells transition into multiciliated cells through a deuterosomal intermediate, a trajectory not previously described. A distinct subset of the derived club cells also showed transcriptional signatures suggesting potential to differentiate into neuroendocrine and goblet cells, revealing broader epithelial plasticity than previously recognized.
Why it matters
This hPSC-based platform provides a tractable human model for studying airway development, epithelial repair mechanisms, and diseases in which club cell damage plays a role, such as asthma and respiratory infections caused by allergens, viruses, or pollutants. It could accelerate the development of disease models and therapeutic strategies targeting airway regeneration.

Airway epithelial homeostasis relies on multiple specialized cell types, with club cells playing central roles in maintaining epithelial integrity and regulating inflammation. Environmental insults such as allergens, viral infections, or pollutants preferentially damage club cells, impairing epithelial repair and contributing to pulmonary diseases. However, the functional properties of club cells remain incompletely defined, and tractable human models are lacking. Herein, we establish a robust platform to differentiate human pluripotent stem cells (hPSCs) into club cells exhibiting their hallmark secretory features, appropriate epithelial organization, and functional properties. Single-cell transcriptomic analyses and lineage trajectory inference revealed unexpected epithelial plasticity: hPSC-derived club cells give rise to multiciliated epithelial cells through a deuterosomal intermediate — a previously uncharacterized trajectory. Additionally, a distinct club cell subset exhibited transcriptional features indicative of neuroendocrine and goblet cell differentiation potential. This study uncovers club cell plasticity and establishes a hPSC-based platform for studying airway development, regeneration and disease modeling.
