  • Detailed SEM analysis of the casted lymphatic structures.

    • Main Results:

    • Successful creation of corrosion casts representing the thyroid lymphatic system.
    • Identified key lymphatic features: variable vessel size, 3D anastomoses, blind endings.
    • Observed V-shaped reliefs indicating valves and bead-like structures from valve closure.
    • Noted surface depressions and saw-toothed figures corresponding to endothelial cell nuclei and boundaries.

    Conclusions:

    • The Mercox corrosion casting technique provides detailed insights into thyroid lymphatic morphology.
    • SEM visualization of these casts is effective for studying lymphatic structures and changes.
    • This method is applicable to lymphatic research across various organs.
