This is a view of apical domains of two adjacent hepatocytes in the guinea pig liver, showing the junctional complexes that attach cells to one another. The bile canaliculus (BC) is defined by the cel...

Proximity of excitatory and inhibitory axon terminals adjacent to pyramidal cell bodies provides a putative basis for nonsynaptic interactions. Video sequence made up of 14 consecutive confocal micros...

Two electron micrographs of smooth muscle cells in a small artery, surrounded by a light gray zone of interspaces composed of an elastic fiber and collagen-rich basement membrane. The elastica intern...

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...

These two micrographs show the outer cell surface of the epithelial cell border in intestine (upper) and stomach (lower) tissue. This surface, called the glycocalyx, is composed of negatively charged...
