Intratracheal instillations deliver solutes directly into the lungs. This procedure targets the delivery of the instillate into the distal regions of the lung, and is therefore often incorporated in studies aimed at studying alveoli. We provide a detailed survival protocol for performing intratracheal instillations in mice.

Here, we present a method for light microscopy analysis of tracheal terminal cells in Drosophila larvae. This method allows for quick examination of branch and lumen morphology in whole animals and would be useful for analysis of individual mutants or screens for mutations affecting terminal cell development.
FAQs
A useful model must account for the C-shaped cartilage rings, membranous posterior wall, smooth muscle, and mucus-lined tissue. These components differ in structure and material properties, so they contribute differently as breathing-related pressure changes produce movement and deformation. Representing the complete arrangement helps researchers evaluate whether the airway can remain open under physiological conditions.
Airflow and wall compliance influence the relationship between pressure changes, deformation, and airway resistance. Compliance describes how readily the wall changes shape in response to loading. Studying these variables together helps identify conditions associated with airway narrowing or collapse and clarifies how mechanical behavior affects the functional performance of the trachea during breathing.
Engineered airway constructs must be assessed under the types of loading associated with normal tracheal function, including breathing-related pressure changes and airflow. Their response can reveal whether the construct maintains suitable stability and function. This information is relevant when determining how repair strategies may perform after implantation or other forms of physiological use.
Researchers combine imaging, mechanical testing, computational models, and engineered airway constructs to examine tracheal stability and function. Imaging characterizes structure, mechanical testing evaluates material behavior, and computational models examine responses under specified conditions. Engineered constructs extend this evaluation to repair strategies, allowing several complementary approaches to inform airway design and assessment.
Computational models provide a way to examine how tracheal structure and material properties respond to breathing-related pressure changes and airflow. By evaluating movement, deformation, airway resistance, compliance, and possible collapse, these models help connect mechanical features with functional outcomes. They also support the design and assessment of implants, stents, and tissue-engineered grafts.
Bioengineering studies use mechanical testing, imaging, computational analysis, and engineered airway constructs to evaluate whether proposed devices or grafts support tracheal stability and function. The resulting information helps researchers examine performance under physiological loading rather than relying only on structural appearance. These methods also improve understanding of how repair strategies may behave in airway applications.
