TLDR
It is probable that at the molecular level the terminal web is formed by elongated branching elements that endows the apex with mechanical stability and anchors it to the body of the cell.About:

Role of microtubules in polarized delivery of apical membrane proteins to the brush border of the intestinal epithelium.
TL;DR: Observations indicate that Golgi- derived carrier vesicles (CVs) containing apical membrane proteins are vectorially guided to the apical cell surface by a retrograde transport along MTs.

The Structure and Properties of the Cell Surface Coat
TL;DR: This chapter discusses the structure and properties of thecell surface coat, a relatively strong, hydrophilic coat which is a permanent feature of the cell surface complex.

Localization of actin and microfilament-associated proteins in the microvilli and terminal web of the intestinal brush border by immunofluorescence microscopy.

TL;DR: Two classes of microfilamentous structures can be documented in the brush border of mouse intestinal epithelial cells: first, the highly ordered microfilaments which make up the cores of the microvilli apparently lack the associated proteins, and second, seemingly less-ordered microfilmaments are found in the terminal web, in which region the myosin, tropomyosin and filamin and alpha-actinin are located.

The terminal web. A reevaluation of its structure and function.
B E Hull,L A Staehelin +1 more
TL;DR: The apical cytoplasm of epithelial cells of the small and large intestines has been examined by freeze-etch techniques as well as conventional and high voltage electron microscopy of sectioned material to gain a better understanding of the fine structural organization of the terminal web region.

Microtubules and microfilaments in newt neurulation
TL;DR: Electron microscopy of presumptive neural cells has been carried out in an attempt to understand the mechanism of morphogenetic cell shape changes and several observations suggest that microtubules contribute to cell elongation by some form of transport mechanism.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY
TL;DR: The stain reported here differs from previous alkaline lead stains in that the chelating agent, citrate, is in sufficient excess to sequester all lead present, and is less likely to contaminate sections.
Journal ArticleDOI
Improvements in epoxy resin embedding methods.
TL;DR: Epoxy embedding methods of Glauert and Kushida have been modified so as to yield rapid, reproducible, and convenientembedding methods for electron microscopy.

Cytochemistry and electron microscopy. The preservation of cellular ultrastructure and enzymatic activity by aldehyde fixation.
TL;DR: A postfixation in osmium tetroxide, even after long periods of storage, developed an image that—notable in the case of glutaraldehyde—was largely indistinguishable from that of tissues fixed under optimal conditions with osmia tetroxides alone.
Journal ArticleDOI
Junctional complexes in various epithelia
TL;DR: The tight junction is impervious to concentrated protein solutions and appears to function as a diffusion barrier or "seal," and the desmosome and probably also the zonula adhaerens may represent intercellular attachment devices.
Journal ArticleDOI
Mitosis in the neural tube
TL;DR: The writer's interest in the mitoses of the neural tube arose as a result of finding, in the neural plate and early neural tube stages of the chick, appearances that seemed not in harmony with the usual accounts.
