Microscopic conduction in cultured strands of neonatal rat heart cells measured with voltage-sensitive dyes.
Microscopic discontinuities in electrical activation were assessed in synthetic strands of neonatal rat myocytes cultured on a growth-directing matrix. An optical method using voltage-sensitive dye (RH-237) and a photodiode technique was used for recordings of membrane potential changes with subcellular resolution. Spatial resolution of the method (diameter of measurement area, 5.5 microns; int...
متن کاملAnisotropic conduction in monolayers of neonatal rat heart cells cultured on collagen substrate.
Anisotropic impulse conduction was studied in neonatal rat heart cell monolayers produced by culturing cells on a growth-directing substrate of collagen. Monolayers consisting of parallel-oriented cells without visible intercellular clefts were selected for experiments; cell lengths and widths were 65.8 +/- 12.5 and 12.2 +/- 3.2 microns (n = 49), respectively. Action potential upstrokes were me...

Anisotropic impulse conduction was studied in neonatal rat heart cell monolayers produced by culturing cells on a growth-directing substrate of collagen. Monolayers consisting of parallel-oriented cells without visible intercellular clefts were selected for experiments; cell lengths and widths were 65.8±+12.5 and 12.2+3.2 gm (n=49), respectively. Action potential upstrokes were measured by usin...
متن کاملThe effect of asymmetric surface potentials on the intramembrane electric field measured with voltage-sensitive dyes.
Ratiometric imaging of styryl potentiometric dyes can be used to measure the potential gradient inside the membrane (intramembrane potential), which is the sum of contributions from transmembrane potential, dipole potential, and the difference in the surface potentials at both sides of the membrane. Here changes in intramembrane potential of the bilayer membranes in two different preparations, ...
