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.

Coat Assembly and GTPases

Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection. Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...
FAQs
The brush’s movement distributes the liquid formulation through controlled shear, helping spread polymers, biomaterials, or other coating solutions across the substrate. This mechanical action supports formation of a continuous layer rather than leaving the material concentrated in one location. The resulting coverage is especially useful when a coating must be placed on an irregular surface or restricted to a localized region.
After the liquid has been spread, solvent evaporation or curing fixes the deposited layer to the surface. These processes convert the initially mobile coating into a more stable film. Which mechanism is relevant depends on the coating formulation, but both provide the transition from a freshly applied liquid layer to a surface modification that can serve a bioengineering purpose.
Controlled shear determines how the brush distributes the coating solution across the substrate. It allows polymers, biomaterials, or related formulations to be spread over the intended area while supporting continuous film formation. This is important in bioengineering because surface coverage can influence properties such as wettability, adhesion, biocompatibility, and resistance to fouling.
A basic workflow places the selected liquid formulation on the target substrate, moves a brush across the intended surface to distribute the material, and then allows solvent evaporation or curing to fix the layer. The method can be directed across a broad area or limited to a particular region, making it adaptable to different coating locations.
The essential setup consists of a brush, a substrate, and a liquid coating formulation. The formulation may contain polymers, biomaterials, or other coating solutions, while the substrate may be a medical device, scaffold, or laboratory surface. Because the technique requires relatively little equipment, it is suitable when researchers need a straightforward approach for surface modification or prototyping.
Bioengineers can use the technique to modify medical devices, scaffolds, and laboratory substrates when they want to alter surface behavior. Depending on the coating, the intended outcome may include improved wettability, adhesion, biocompatibility, or resistance to fouling. Its simple equipment requirements also support prototyping, while brush placement allows treatment of irregular or localized regions.
