Demonstration of Extracellular Space by Freeze-Drying in the Cerebellar Molecular Layer [PDF]
, 1966 In electron micrographs of the molecular layer of the mouse cerebellum frozen within 30 sec of circulatory arrest and subsequently dried at -79 °C an appreciable extracellular space was found between the axons of the granular cells.

Current Techniques for Investigating the Brain Extracellular Space. [PDF]
Front Neurosci, 2020 The brain extracellular space (ECS) is a continuous reticular compartment that lies between the cells of the brain. It is vast in extent relative to its resident cells, yet, at the same time the nano- to micrometer dimensions of its channels and reservoirs are commonly finer than the smallest cellular structures.

Determination of Extracellular Space in Amphibian Muscle [PDF]
The Journal of General Physiology, 1967 The volumes of distribution of inulin and dextran in the sartorius, stomach, and cardiac muscle of the frog agree rather closely. That these spaces represent the volume of extracellular water is supported by the observation that efflux of sucrose can be divided into a fast and a slow phase and that the fast-moving fraction corresponds closely with ...

The Extracellular Space of Voluntary Muscle Tissues [PDF]
The Journal of General Physiology, 1967 The volume occupied by the extracellular space has been investigated in six types of voluntary muscles: sartorius (frog), semitendinosus (frog), tibialis anticus longus (frog), iliofibularis (frog), rectus abdominis (frog), and diaphragm (rat). With the aid of four types of probe material, three of which are conventionally employed (inulin, sorbitol ...

Protein Dynamics in the Plant Extracellular Space [PDF]
Proteomes, 2016 The extracellular space (ECS or apoplast) is the plant cell compartment external to the plasma membrane, which includes the cell walls, the intercellular space and the apoplastic fluid (APF). The present review is focused on APF proteomics papers and intends to draw information on the metabolic processes occurring in the ECS under abiotic and biotic ...

Diffusion in Brain Extracellular Space [PDF]
Physiological Reviews, 2008 Diffusion in the extracellular space (ECS) of the brain is constrained by the volume fraction and the tortuosity and a modified diffusion equation represents the transport behavior of many molecules in the brain. Deviations from the equation reveal loss of molecules across the blood-brain barrier, through cellular uptake, binding, or other mechanisms ...

Extracellular space in some isolated tissues [PDF]
The Journal of Physiology, 1974 1. The spaces occupied by isotopically labelled inulin, polyethylene glycol, mol. wt. 4000 (PEG 4000), polyethylene glycol, mol. wt. 1000 (PEG 1000) and sucrose in metabolizing mammalian kidney and liver slices and in toad bladder epithelial cell preparations incubated in vitro have been examined.2.

Changes in diffusion through the brain extracellular space [PDF]
, 2004 ECS (extracellular space) works as the microenvironment of brain cells. Diffusion through ECS may be described through an effective diffusion coefficient, De, which in turn depends on ECS porosity, ε, and tortuosity, T. In the present research, diffusion

Aquaporin-4-dependent K(+) and water transport modeled in brain extracellular space following neuroexcitation. [PDF]
, 2013 Potassium (K(+)) ions released into brain extracellular space (ECS) during neuroexcitation are efficiently taken up by astrocytes. Deletion of astrocyte water channel aquaporin-4 (AQP4) in mice alters neuroexcitation by reducing ECS [K(+)] accumulation ...

Local diffusion in the extracellular space of the brain
Neurobiology of Disease, 2023 The brain extracellular space (ECS) is a vast interstitial reticulum of extreme morphological complexity, composed of narrow gaps separated by local expansions, enabling interconnected highways between neural cells. Constituting on average 20% of brain volume, the ECS is key for intercellular communication, and understanding its diffusional properties ...
