Apical membrane permeability of MDCK cells
American Journal of Physiology-Cell Physiology, 1996The osmotic water permeability (Pf) and permeability to nonelectrolytes were determined for the apical membrane of clonal strain Madin-Darby canine kidney (MDCK) C12 cells cultured as cysts with the apical membrane facing the surrounding medium. Pf and solute permeabilities were calculated from the rate of volume change of cysts by digitizing images ...

Microfluidic measurement of individual cell membrane water permeability
Analytica Chimica Acta, 2021This paper reports a microfluidic lab-on-chip for dynamic particle sizing and real time individual cell membrane permeability measurements. To achieve this, the device measures the impedance change of individual cells or particles at up to ten time points after mixing with different media, e.g.

A Highly Efficient Tumor‐Targeting Nanoprobe with a Novel Cell Membrane Permeability Mechanism
Advances in Materials, 2019Efficient tumor targeting has been a great challenge in the clinic for a very long time. The traditional targeting methods based on enhanced permeability and retention (EPR) effects show only an ≈5% targeting rate.

Asymmetrically Permeable Membrane Channels in Cell Junction
Science, 1980Asymmetric membrane junctions were formed in culture by pairing two cell types which, in their respective homologous junctions, have cell-cell channels of different permselectivities. The channels in the asymmetric junction, presumably made of unequal channel precursors, displayed directional permselectivity; fluorescent labeled glutamic acid (700 ...

Micropatterning Cells on Permeable Membrane Filters
2014Epithelium is abundantly present in the human body as it lines most major organs. Therefore, ensuring the proper function of epithelium is pivotal for successfully engineering whole organ replacements. An important characteristic of mature epithelium is apical-basal polarization which can be obtained using the air-liquid interface (ALI) culture system.

Membrane permeability of isolated lung cells to nonelectrolytes
American Journal of Physiology-Cell Physiology, 1977Mixtures of viable endothelial and epithelial cells were separated by enzymatic digestion from rabbit lung and recovered by centrifugation. The cells were mixed with an extracellular marker and packed by centrifugation into small-diameter polyethylene tubing and pulsed with tritiated water and 14C-labeled alcohols.

Cell membrane permeability in hypertension.
Clinical physiology and biochemistry, 1989A great deal of evidence has been presented which suggests that a generalized increase in cell membrane permeability to various ions is a fundamental defect associated with hypertension. In addition, some of the evidence is supportive of a central role of this defect in the pathogenesis of hypertension.
