Nasal epithelial cells, obtained through superficial scrape biopsy of human volunteers, are expanded and transferred onto tissue culture inserts. Upon reaching confluency, cells are grown at air liquid interface, yielding cultures of ciliated and non-ciliated cells. Differentiated nasal epithelial cell cultures provide viable experimental models for studying the respiratory mucosa.

FAQs
Polarization organizes the cells into an airway-like epithelial layer with distinct functional surfaces. This organization allows the culture to reproduce coordinated barrier behavior and surface transport more effectively than an unstructured cell population. In bioengineering, polarized layers therefore provide a more physiologically relevant foundation for airway-on-a-chip platforms and engineered respiratory tissues.
Tight junctions connect neighboring epithelial cells and regulate how easily substances pass through the layer. Their activity makes barrier permeability an experimentally relevant feature of engineered airway models. By incorporating this junction-controlled barrier, researchers can examine airway integrity and changes associated with inflammation, infection, toxic exposures, or tissue repair in a controlled in vitro setting.
Ciliated cells contribute active surface movement that transports mucus across the epithelial layer. Including this specialized function helps engineered models represent airway clearance rather than merely reproducing a passive cellular barrier. This feature is particularly relevant when bioengineered systems are designed to study respiratory physiology, airway injury, or how environmental exposures affect epithelial surface behavior.
Their human origin and specialized airway functions can improve the biological relevance of engineered platforms. When the cells form polarized layers with tight junctions and ciliated surface activity, the resulting model captures several features of human airway biology simultaneously. This makes the system more representative for studying respiratory processes than models that reproduce fewer airway-specific characteristics.
The cells can first be expanded in culture and then differentiated under controlled conditions. Differentiation supports formation of a polarized epithelial layer containing barrier-regulating tight junctions and mucus-moving ciliated cells. This staged approach enables researchers to move from obtaining sufficient cellular material to establishing a more physiologically relevant airway model for subsequent experiments.
Researchers can incorporate these cells into airway-on-a-chip systems, engineered respiratory tissues, and other in vitro platforms. Such models support investigations of inflammation, infection, toxic exposures, and tissue repair while retaining features of human airway biology. Their use is valuable when experimental goals require a controlled engineered environment with a relevant epithelial barrier and specialized surface functions.
