Barrier Function of Cell Layers

The ECIS Method

Measurement of barrier function of cell layers in tissue culture via ECIS has proven to be a significant and rapidly growing use of this technology. The utilization of ECIS to monitor barrier function was first demonstrated in 1992 using bovine pulmonary endothelial cells exposed to thrombin [ "Electrical method for detection of endothelial cell shape change in real time: assessment of endothelial barrier function" Proc. Natl. Acad. Sci. USA. 89: 7919-7923, 1992 ].

In the decade following that publication, endothelial cell biologist have increasingly found barrier function measurements via ECIS to be an attractive alternative to techniques involving the use of membrane inserts and Ussing chambers. In addition to its convenience in gathering transcellular resistance (TER) data with a minimum of labor, the measurement requires no tagged compounds and associated sampling/measuring techniques. The relatively low values of the transcellular resistance for most endothelial layers (for example 10 ohm cm^2 ) make precise determinations of this value difficult with other technologies such as resistance measurements of cell layers upon filter substrates.

True barrier function measurements

Cell layers with very high TER values such as endothelial cells from the brain and epithelial cells exhibiting tight junctions can be measured electrically using porated membrane supports as well as with ECIS, but there is an important distinction between the capabilities of these methods. In both cases, the true barrier function (the resistance of the paracellular pathway between the cells) is complicated by the constricted current flow in the space between the basal cell membrane and the cell support. This complication is equally true for measurements using tagged compound. This is shown in the figure below where we see a cartoon version of cells upon a porated filter. Note that for molecules to travel from the lower chamber to the space above the cell layer, they must also travel in the constricted space beneath the cells to reach the intercellular junctions. Because of this, one does not measure the true barrier function but rather a combination of the constricted paths beneath the cells and the transcellular pathway.

The ECIS method is unique in being able to distinguish between these two pathways, since they each affect the measured resistance and capacitance monitored by ECIS in different ways. Using a published model, the true barrier function due to intercellular junctions can be extracted from ECIS data.

Garcia, et al., have used this model to address the changes in impedance when bovine pulmonary arterial endothelial cell layers are exposed to VEGF. Data analyzed by the model show a drop in the true barrier function in response to the growth factor.
