EphA4 is not required for Purkinje cell compartmentation
Developmental Brain Research, 2002The Purkinje cells of both the adult and the developing cerebellar cortex are organized into parasagittal stripes or 'segments' expressing a variety of biochemical markers. We show that in the developing mouse cerebellar cortex, members of the Eph receptor gene family are expressed in mediolaterally alternating Purkinje cell segments.

Compartmentalization of human natural killer cells
Molecular Immunology, 2005Human natural killer (NK) cells are bone marrow-derived cells that are found in the bloodstream, but can extravasate into various tissue sites upon inflammation. NK cells that migrate toward inflamed sites must be activated prior to their extravasation. However, the factors responsible for NK cell compartmentalization are not clearly defined.

A stochastic compartmental model of bone cells
International Journal of Bio-Medical Computing, 1987Cellular dynamics play an important role in bone remodelling. The mesenchymal cells, osteoclasts, osteoblasts and osteocytes are the four types of bone cells, which mediate bone remodelling involving bone formation and resorption throughout the human life-span.

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 ...

Cell Compartmentalization of Cholesterol Biosynthesisa
Annals of the New York Academy of Sciences, 1996Thus, the results showing the presence of cholesterol synthetic enzymes in peroxisomes (see references 1, 4, 5, 6, 7, 8, 12, 13, 20, 21, 22, 24, 25, and 26), the reduced levels of cholesterol synthesis enzymes and cholesterol synthetic capacity of cells and tissues lacking peroxisomes, 26, 37, 39 and the low serum cholesterol levels in patients ...

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 ...
