    Area of Science:

    • Cell Biology
    • Physiology
    • Tissue Engineering

    Background:

    • Endothelium, once viewed as a passive barrier, is now recognized as a dynamic tissue.
    • Pulmonary endothelium comprises metabolically active cells with significant functional roles.

    Purpose of the Study:

    • To highlight the active role of pulmonary endothelial cells in regulating systemic arterial blood composition.
    • To emphasize the contribution of endothelial cells to thrombosis, hemostasis, and immune reactions.
    • To underscore the importance of cell biology in understanding endothelium in health and disease.

    Main Methods:

    • Isolation and culture of pulmonary endothelial cells.
    • Assessment of endothelial cell biochemical and ultrastructural properties.
    • Consideration of fluid mechanical forces on endothelial cells.

    Main Results:

    • Pulmonary endothelial cells actively interact with circulating substrates and formed elements.
    • These interactions influence target organ functions and systemic arterial blood composition.
    • Endothelial cell activity is crucial for thrombosis, hemostasis, and immune responses.

    Conclusions:

    • The cell biology of endothelial cells is fundamental to understanding endothelium as a tissue.
    • Advances in culturing pulmonary endothelial cells facilitate deeper insights.
    • Integrating biochemical, ultrastructural, and physical factors is essential for future research on endothelium in health and disease.
