A Compartmentalized Device for the Culture of Animal Cells
Biomaterials, Artificial Cells and Artificial Organs, 1989A simply-constructed device for the batch culture of animal cells is described that takes advantage of gas-permeable polymer films and continuous dialysis of nutrient fluids. The design separates a cell-growth chamber from a nutrient-medium reservoir with a dialysis membrane, effectively compartmentalizing growth and feeding functions.

Metabolic control and compartmentation in single living cells
Cell Biochemistry and Function, 1983AbstractMicrospectrofluorometry of cell coenzymes (NAD(P)H, flavins) in conjunction with sequential microinjections into the same cell of metabolites and modifiers, reveals aspects of the regulatory mechanisms of transient redox changes of mitochondrial and extramitochondrial nicotinamide adenine dinucleotides.

Subcellular compartmentalization of the luteal cell in the ovary of the dog
Cell and Tissue Research, 1975The compartmentalization of the parenchyma of the corpus luteum in the dog was studied by both 100 and 1000 KV electron microscopy. The organells within the luteal cell are oriented with a high degree of consistency towards the pericapillary space. Characteristically, the avascular pole and the lateral margins of the cell posses predominantly stacked ...

Entropy decrease associated to solute compartmentalization in the cell
Biosystems, 2009We have deduced equations to quantify the entropy associated to the compartmentalization of components in eukaryotic cells as a function of cell and compartment volumes, and of the concentration of solutes. On the basis of known and plausible values of volume and solute concentrations and the deduced equations, we estimate that the contribution of ...

Reduced compartmental models of neocortical pyramidal cells
Journal of Neuroscience Methods, 1993Model neurons composed of hundreds of compartments are currently used for studying phenomena at the level of the single cell. Large network simulations require a simplified model of a single neuron that retains the electrotonic and synaptic integrative properties of the real cell.

COMPARTMENTATION OF PROTEINS IN THE ENDOMEMBRANE SYSTEM OF PLANT CELLS
Annual Review of Plant Physiology and Plant Molecular Biology, 1996▪ Abstract This review focuses on four interrelated processes in the plant endomembrane system: compartmentation of proteins in subdomains of the endoplasmic reticulum, mechanisms that determine whether storage proteins are retained within the ER lumen or transported out, the origin and function of biochemically distinct vacuoles or prevacuolar ...

Compartmentalization of the splicing machinery in plant cell nuclei
Trends in Plant Science, 2004The cell nucleus is a membrane-surrounded organelle that contains numerous compartments in addition to chromatin. Compartmentalization of the nucleus is now accepted as an important feature for the organization of nuclear processes and for gene expression.

Control of cell adhesion and compartmentalization in the intestinal epithelium
Experimental Cell Research, 2011Continuous cell renewal in the intestinal mucosa occurs without disrupting the integrity of the epithelial layer. Despite the restrictions imposed by strong cell-to-cell adhesions, epithelial intestinal cells migrate constantly between tissue compartments. Alterations in cell adhesion and compartmentalization play key roles in diseases of the intestine.

Compartmentalized cell signaling in caveolae
Proceedings, annual meeting, Electron Microscopy Society of America, 1995Caveola undergo an internalization cyclic that begins with the conversion of a flat segment of membrane into a vesicle and ends when that vesicle returns to the cell surface. During this cycle, resident molecules are sequestered in the interior of the vesicle where they perform special functions.
