Drug bioavailability studies commonly employ in vitro barrier tissue models consisting of epithelial and endothelial cells. These experiments require that the cell barrier quality be assessed regularly, which is usually performed using various labeled substrates and/or evaluation of transepithelial (transendothelial) electrical resistance (TEER). This technique provides information on the integrity of the monolayer, but not on differentiation-induced changes in the cell morphology. The present work shows that impedance spectroscopy can be applied to monitor both the integrity of the monolayer and the morphological changes of Caco-2 cells. The growth kinetics of the apical membrane was determined by calculating the electrical capacitance of the cell monolayer. In the course of differentiation, the most pronounced changes in the expression levels were observed for the mRNAs that encode SLC30A10 and SLC23A3 transporters. Their increase correlated with an increase in the apical membrane area, indicating that SLC30A10 and SLC23A3 mRNA levels assessed by qRT-PCR may be employed as cell differentiation biomarkers in Caco-2 models.
