[Ultrastructure of adipose cells]

M Rupec

    Dermatologica
    |January 1, 1981

    Summary
    This summary is machine-generated.

    This study reveals new ultrastructural details of human fat cells, including filament-surrounded lipid droplets and endoplasmic reticulum involvement in lipid synthesis. These findings enhance our understanding of adipocyte morphology and lipid metabolism.

    Area of Science:

    • Cell Biology
    • Histology
    • Adipose Tissue Biology

    Context:

    • Normal subcutaneous fatty tissue in adult humans was examined using advanced ultrastructural techniques.
    • Previous knowledge of adipocyte morphology is expanded upon with novel observations.

    Purpose:

    • To investigate the ultrastructure of normal human subcutaneous adipose tissue.
    • To identify and characterize previously unobserved morphological features within adipocytes.

    Summary:

    • Observations include lipid droplets ensheathed by filament systems.
    • Lipid-like material was found within the smooth endoplasmic reticulum cisterns.
    • Complex lipid granules, potentially lipofuscin, and filamentous nuclear inclusions were identified.
    • The presence of lipomicrons is influenced by fixation methods.
