What are primary bronchial epithelial cells?
Primary bronchial epithelial cells are cells that line the airways and play a key role in respiratory health.
How is the cell culture maintained?
The cell culture is maintained at the air-liquid interface with regular medium changes to support growth.
What is TEER and why is it important?
TEER stands for transepithelial electrical resistance, and it is a measure of the integrity of the cell layer.
Can this method be used for other types of epithelial cells?
While this method is optimized for bronchial epithelial cells, similar techniques may be adapted for other epithelial types.
What are the advantages of this method?
This method is cost-effective, reproducible, and provides a good representation of human airway epithelium.
How long can PBECs be stored?
PBECs can be cryopreserved for long-term storage in liquid nitrogen.
