    Area of Science:

    • Pulmonary Medicine
    • Microscopy
    • Cell Biology

    Background:

    • The lung's structure features extensive blood-tissue and gas-tissue interfaces.
    • These interfaces facilitate detailed study using scanning electron microscopy (SEM).

    Purpose of the Study:

    • To describe and discuss various SEM sample preparation techniques for lung tissue.
    • To enable morphological and morphometrical analysis of adult and fetal lung surfaces.
    • To characterize lung structures, cells, and secretions using SEM.

    Main Methods:

    • Utilized scanning electron microscopy (SEM) for lung tissue observation.
    • Employed diverse sample preparation techniques for SEM analysis.
    • Performed vascular injections for observing the lung's vascular network.
    • Studied cellular components like alveolar macrophages in situ and in culture.

    Main Results:

    • SEM allows detailed morphological and morphometrical studies of lung fine structures.
    • Characterized epithelial cells, secretions (mucus, surfactant), and vascular networks.
    • Observed pre- and post-natal lung development and alveolar macrophages.

    Conclusions:

    • SEM is a valuable, modern method for observing lung surfaces.
    • Provides dynamic insights into lung fine structures and histophysiological processes.
    • Essential for comprehensive lung parenchyma studies.
