Depolarization of the membrane potential by hyaluronan
Journal of Cellular Biochemistry, 2010AbstractThe membrane potential is mainly maintained by the K+ concentration gradient across the cell membrane between the cytosol and the extracellular matrix. Here, we show that extracellular addition of high‐molecular weight hyaluronan depolarized the membrane potential of human fibroblasts, human embryonic kidney cells (HEK), and central nervous ...

Relationship of epithelial membrane potentials to corneal potential
Experimental Eye Research, 1973Abstract The rabbit corneal potential arises as the sum of three steps across the epithelium. These occur across the squamous cell outer membrane, at the transition region between wing and basal cells, and across the basal cell inner membrane. Variations in corneal potential are inversely proportional to outer membrane potential.

Membrane potential, surface potential and ionic permeability
Physics Letters A, 1979To clarify contributions to cellular transmembrane potential concentration potentials of phospholipid bilayer membranes and surface potentials of phospholipid monolayers were measured with respect to salt concentrations and various surface charge densities.

Membrane Potential and Muscle Function
Annual Review of Medicine, 1969The relationship between the function of a whole muscle and the elec trical polarization of its individual fiber membranes is not a simple or direct one. To be sure, the process known as excitation-contraction coupling requires at least a minimum of fairly well-defined properties and events at the fiber surfaces, but both the resting voltages across ...

Membrane potentials inStentor coeruleus
Protoplasma, 1971The membrane potential ofStentor coeruleus was measured by means of glass microelectrodes. The tips of the electrodes had a diameter of 2 μ, and were filled with 0.1 M KCl. The maximum value of the potential is −30.8±8.6 mV and is reached within 600–800 msec after electrode insertion; the potential then decreases to a negative value of a few mV within ...

Membrane potential of juxtaglomerular cells
Nature, 1976THE juxtaglomerular granular cell of the kidney is the site of renin storage and release, and is located most commonly within the media of the afferent arteriole, often in close apposition to the distal tubule and to sympathetic nerve endings. Morphologically, it seems to be a smooth muscle cell that has been modified for secretory activity, and ...
