title: Adhesion of intermediate filaments and lipid droplets in adrenal cells studied by field emission scanning electron microscopy.
abstract: High-resolution field emission scanning electron microscopy was used to study the organisation of intermediate filaments around lipid droplets and their binding to these droplets, in primary culture of bovine adrenal cells. Whole-mount preparations of intermediate filaments and bound lipid droplets were prepared from cells grown on Formvar-coated grids and processed by freeze-drying. Intermediate filaments were seen as an interconnected network enveloping the entire droplet. The bound filaments appear to be directly adherent to the surface of the droplet and hence take on its curved contour. The binding of the filaments to the droplets was determined by means of tilting. This study provides a new approach to investigate the cytoskeleton and its associated structures with high-resolution three-dimensional images.
