Contrasting the Toxicological Responses of Differentiated and Undifferentiated Primary Airway Epithelial Cells Webinar

March 30, 2023, at 12:00 PM ET


Traditional in vitro airway models are often unable to provide meaningful and accurate toxicological assessments of candidate compounds due to their lack of physiological relevance. However, advanced in vitro 3-D models may provide more predictive information for use in pharmaceutical development and basic research. To test this, ATCC scientists constructed 3-D airway models comprising fully differentiated or undifferentiated primary human bronchial tracheal epithelial cells (HBECs). They then challenged these in vitro models to short and long term exposure to the toxicant cadmium chloride and the antimicrobial pentamidine. Join this webinar to see data suggesting that these advanced models can be used to assess the toxicological response to both short- and long-term exposure to unknown compounds, serving as useful tools for future airway toxicity research. After the presentation, join us for a lively discussion as our experts answer your questions.

Key Points

  • This study demonstrates the utility of airway models as physiologically relevant models for safety research using compounds relevant to industrial hygiene and pharmaceutical development.
  • We compared toxicological response in airway models to 2-D models comprised of freshly seeded undifferentiated HBECs. Depending on the compound administered, significant differences in response were observed between the two different models.
  • This report also provides an overview on how to perform long-term testing on airway models.
