    Area of Science:

    • Histology
    • Pathology
    • Microscopy

    Background:

    • Traditional methods for visualizing soft tissue internal structures can be complex and time-consuming.
    • Scanning electron microscopy (SEM) offers high-resolution imaging but often requires specialized sample preparation.

    Purpose of the Study:

    • To develop a simple, rapid, economic, and reliable method for visualizing the internal structure of soft tissues.
    • To enable detailed examination of cellular and extracellular components using SEM from routinely processed samples.

    Main Methods:

    • A novel technique involving fracturing paraffin-embedded soft tissue samples at room temperature.
    • Utilizing the same sample for both light microscopy and subsequent SEM analysis.
    • Observing exposed cellular and extracellular details without specialized equipment.
