Quick-frozen deep-etched preparation of skeletal muscle tissue shows the muscle fiber and associated extracellular components. The basement membrane (labeled basal lamina) lies adjacent to the undulat...

This electron micrograph shows a region of the brush border of the cat intestine. Tufted and branched polysaccharide filaments, each a few nanometers thick, extend from the microvilli to make up the ...

This electron micrograph highlights a darkly-stained glycocalyx rim of the brush border of the intestinal epithelium of the cat, stained en bloc with colloidal thorium. The glycocalyx is composed of ...

COS 7 cell expressing Organelle LightsTM PM-GFP (Invitrogen)consisting of the myristoylation/palmitoylation sequence from Lck tyrosine kinase. Images were collected with a 63X 1.4 NA Plan-Apochromat ...

We examined the structural organization of cytoskeletal components and membrane systems in neurons of well preserved biopsy material from Alzheimer’s disease (AD). Information was obtained from thin...

This electron micrograph shows the basal lamina along the midgut epithelium of the flea. Unlike the vertebrate basal lamina, which appears as a homogenous layer, the basal lamina in insects often app...

Electron micrograph of a nerve from the mesentery of a rat shows groups of unmyelinated axons wrapped by deeply invaginating Schwann cells in cross section. Surrounding the Schwann cell wrapping is a ...

Transmission electron micrograph of spectrin in cell fractionation. Dr. V. T. Marchesi and colleagues took advantage of the high purity of red cell ghosts obtained by hypotonic lysis to analyze the p...

Fluorescent micrograph showing human induced pluripotent stem (iPS) cell-derived cardiomyocytes (CDI iCell) treated with 2 microM Erythromycin for 4 hours and stained for cell membrane permeabilizatio...
