    Human arterial endothelium exhibits diverse cell patterns, including fusiform, polygonal, and giant cells. These patterns correlate with intimal thickening and lipid deposition in carotid arteries, pulmonary trunk, and aorta.

    Area of Science:

    • Cardiovascular Biology
    • Histology
    • Vascular Endothelium Research

    Background:

    • The arterial endothelium forms a critical interface regulating vascular health.
    • Endothelial cell morphology can vary and potentially reflect underlying vascular conditions.

    Purpose of the Study:

    • To characterize the en face morphology of human arterial endothelium.
    • To investigate the relationship between endothelial patterns and intimal structure in major human arteries.

    Main Methods:

    • Silver nitrate staining of endothelial cell borders in human carotid arteries, pulmonary trunk, and aorta.
    • En face examination of endothelial cell patterns.
    • Transverse sectioning to correlate endothelial morphology with underlying intimal structure.

    Main Results:

    • Consistent background pattern of fusiform cells observed across all examined vessels.
    • Variable superimposed patterns of polygonal and giant endothelial cells were noted.
    • Increased intimal fibrous thickening and lipid deposition were associated with disorganized endothelial patterns and multinucleated giant cells.

    Conclusions:

    • Human arterial endothelium displays diverse cellular arrangements.
    • Endothelial cell patterns show a tendency to associate with intimal pathology, particularly fibrosis and lipid accumulation.
