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:

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.
