TLDR
Electron microscopic investigation in the taste bud of the foliate papillae of the rabbit has distinguished two filamentous structures: microtubule and filaments, which are prominent in number as compared to microtubules.Abstract:

Cold and Metabolic Inhibitor Effects on Cytoplasmic Microtubules and the Golgi Complex in Cultured Rat Epiphyseal Chondrocytes
TL;DR: The effects of cold and metabolic inhibitors on cultured chondrocytes have been investigated to characterize further the relationship between these organelle systems and support the concept of an important role of microtubules in the organization of the Golgi complex.

A quantitative evaluation of the area and the number of the somata in the human circumvallate taste bud by electron microscope
TL;DR: The epithelium of the human circumvallate papillae was divided into three transverse portions from its superior surface; upper (UP), middle (MP) and lower portion (LP), and it was suggested that the cell number in one taste bud is 10.7 to 27.3 from area distributions of somata.

[A quantitative observation of the human circumvallate taste bud with electron microscope (author's transl)].
TL;DR: The quantitative morphometrical analysis employed in present study will be useful in the fields of physiology, histology and clinical medicine.

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.

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.

Staining of Tissue Sections for Electron Microscopy with Heavy Metals
TL;DR: Certain hitherto unobserved details are revealed and some sort of specificity exists, although the factors involved are not yet understood.

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.

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.
