Biological Models of the Lower Human Airways-Challenges and Special Requirements of Human 3D Barrier Models for Biomedical Research

In our review, we want to summarize the current status of the development of airway models and their application in biomedical research. We start with the very well characterized models composed of cell lines and end with the use of organoids. An important aspect is the function of the mucus as a component of the barrier, especially for infection research. Finally, we will explain the need for a nondestructive characterization of the barrier models using TEER measurements and live cell imaging. Here, organ-on-a-chip technology offers a great opportunity for the culture of complex airway models.

Automated summary

The review summarizes the development and application of airway models, ranging from cell line models to organoids. The function of mucus as a barrier component and the need for nondestructive characterization of barrier models using TEER measurements and live cell imaging are emphasized. Organ-on-a-chip technology presents a great opportunity for cultivating complex airway models.
