The general and familiar idea of the cell membrane is that of a barrier to diffusion encompassing the entire cell surface. This idea derives largely from work with a few cell types: nerve, striated muscle, blood, and gamete cells. These are, however, rather peculiar cells. They are generally not in direct contact with each other but are separated by wide fluid-filled spaces. I shall deal here with the question of what happens to the diffusion barrier when two cell membranes are brought close… 

Communication between Cells of Different Type

TLDR
Paired cultured cells from different organs and species are paired, measuring the communication between cells electrically, and it is found that the membranes must undergo profound structural changes in such a way that previously impermeable surface regions become highly permeable.

Intercellular communication and some structural aspects of membrane junctions in a simple cell system

TLDR
Chironomus salivary gland consists of a chain of 30 giant cells and 4 to 6 flat cells spanning a lumen that is in communication with each other and in contact with small inorganic ions, fluorescein and Procion Yellow.

Structure and function of intercellular junctions.

STUDIES ON BLOOD CAPILLARIES : I. General Organization of Blood Capillaries in Muscle

TLDR
The wall of the blood capillaries of skeletal muscles and myocardium of the rat, guinea pig, and hamster consists of three consecutive layers or tunics: the endothelium (inner layer), the basement membrane with its associated pericytes (middle layer), and the adventitia (outer layer).

STUDIES ON AN EPITHELIAL (GLAND) CELL JUNCTION I. Modifications of Surface Membrane Permeability

TLDR
Membrane permeability of an epithelial cell junction (Drosophila salivary gland) was examined with intracellular microelectrodes and with fluorescent tracers and the organ here, rather than the single cell, appears to be the unit of ion environment.

STUDIES ON AN EPITHELIAL (GLAND) CELL JUNCTION. II. SURFACE STRUCTURE.

TLDR
The surface structure of a gland epithelium (Drosophila salivary gland), particularly that at the junction between cells, was examined under the electron microscope, and the implications of surface structure in intercellular permeability are discussed.

A STUDY OF THE STRUCTURE AND DISTRIBUTION OF THE NEXUS

TLDR
The nexuses which occur in epithelia in frog skin and rat salivary gland are distributed as though to provide seals against electrochemical backleaks and sites of chemical exchange between cell interiors.

TLDR
The purpose of this investigation was to de termine whether m a m m a l i a n liver cells are coupled ionically, and to investigate the zonula occludens described by F a r q u h a r and Palade.

Intercellular Attachment in the Epithelium of Hydra As Revealed by Electron Microscopy

TLDR
It is suggested that septate desmosomes in Hydra form barriers to the movement of water into intercellular spaces and thus help to protect the organism's internal environment.

Intercellular Communication: Renal, Urinary Bladder, Sensory, and Salivary Gland Cells

TLDR
In four epithelial cell systems (salivary gland, renal, urinary bladder, and sensory cells) cells are interconnected as far as much of their ion content is concerned, at least three epithelia is associated with the presence of certain close-junctional membrane complexes.

ULTRASTRUCTURE OF EXCITABLE MEMBRANES AND THE CRAYFISH MEDIAN‐GIANT SYNAPSE

TLDR
The evidence that has led me to advance the unit membrane theory is reviewed and a treatment in some detail of certain aspects of peripheral nerve fiber structure is treated, drawing largely on the work of Gasser,12J3 who showed that unmyelinated nerve fibers consist of axons running in troughs in the surfaces of Schwann cells.

This paper will mainly be concerned with observations on amphibian development, although it is realized that some of the phenomena to be touched upon have been inore thoroughly investigated in other foriiis, such as the echinoderms.
