STUDY OF CELLS ATTACHMENT USING IMPEDANCE SPECTROSCOPY TECHNIQUE

摘要

In this paper we report on the electrical impedance spectroscopy characterization of the attachment of two mammalian cell lines: endothelial cells (RFPEC) and fibroblast cells (V79). For electrical cell-substrate impedance sensing (ECIS) of the endothelial cells a commercially available eight-well cell culture impedance array (ECIS-8W1E) was used. The impedance measurements were recorded with cell culture medium (without cells) and with endothelial cells or fibroblast cells in the culture medium over a frequency range from 100 Hz to 100 kHz. The impedance measurements were compared to the equivalent circuit model. The impedance measurements were also simulated using COMSOL Multiphysics™, a commercially available modeling package.
