Presented is a method for air-inflation with vascular perfusion-fixation of the lungs that preserves the location of cells within airways, alveoli and interstitium for structure-function analyses. Constant airway pressure is maintained with an air-inflation chamber while fixative is perfused via the right ventricle. Lungs are processed for histologic studies.

FAQs
Controlled pressure or volume determines how far the warm agarose expands the lung before fixation. This control helps preserve the organ in an expanded state without relying on uneven, uncontrolled filling. Consistent inflation conditions are important because they support comparable histological sections and make measurements of airway structure, alveolar morphology, and regional tissue changes more reliable.
Warm liquid agarose can be introduced through the trachea and distributed through the airways and alveoli. Cooling then changes the liquid into a supporting gel that holds the lung in the expanded configuration. This sequence matters because structural support is established before fixation, sectioning, or imaging, helping preserve delicate alveolar architecture for later assessment.
The gel provides internal support that helps maintain the spatial organization of airways and alveoli during tissue preparation. By reducing variation in the preserved expanded state, Agarose Lung Inflation improves consistency between sections and supports more dependable evaluation of morphology. This is especially relevant when regional tissue changes must be compared across specimens or experimental conditions.
The procedure begins by introducing warm liquid agarose through the trachea at a controlled pressure or volume. The lung is then allowed to cool so the material solidifies and supports expansion. After gel formation, the prepared tissue can undergo fixation, sectioning, or imaging. These stages connect controlled filling with preservation and subsequent structural analysis.
Researchers may select this preparation method when they need consistent structural preservation for pulmonary pathology, disease modeling, morphometry, or assessment of responses to injury or treatment. Its value lies in maintaining lung architecture sufficiently for comparisons of airway structure, alveolar morphology, and regional changes. The resulting sections or images can therefore support more reliable tissue evaluation.
In medical and biomedical research, the prepared lung can support examination of airway structure, alveolar morphology, and regional tissue changes. It is also suited to morphometric analysis, which compares structural features quantitatively or systematically. By improving section consistency and preserving architecture, the method helps investigators assess disease-related changes, injury responses, or structural effects associated with treatment.
