Dielectric behaviour of gap junction connected cells: a microscopic approach
2002
The dielectric behaviour of interconnected cells is simulated by taking into account the 'real' shape. In previous work, we derived the polarizability of non-
spherical,
shelled, particles by solving the related integral equation using a spectral decomposition. The permittivity and impedance modulus spectra of
gap junctionconnected cells are compared with those provided by a suspension of ellipsoids (
prolate spheroids) having the same shape as the individual cells connected through
gap junction, and the same volume fraction. This approach aims to provide a microscopic hint on the effect of the closing of
gap junctionsreported on the dielectric behaviour of ischaemic tissues, as well as to offer a rough approximation of a tissue by considering high concentrations of oriented
gap junctionconnected cells.
