Frequently Asked Questions

What are tracheal brush cells?

Tracheal brush cells are rare cholinergic chemosensory epithelial cells found in the trachea.

Why is isolating brush cells important?

Isolating brush cells is crucial for studying their role in airway immunity and remodeling.

What method is used for isolation?

The method involves separating the tracheal epithelium and using a short incubation with papain.

How does this method improve cell viability?

Shorter incubation times with digestive enzymes help maintain cell viability.

What applications does this method have?

This method can be used for transcriptional analysis and studies of upper airway epithelium.

Brush cells are rare cholinergic chemosensory epithelial cells found in the naïve mouse trachea. Due to their limited numbers, ex vivo evaluation of their functional role in airway immunity and remodeling is challenging. We describe a method for isolation of tracheal brush cells by flow cytometry.
