My colleagues at the US EPA are currently investigating that. We do air-liquid interface exposures to air pollutants and are interested in using the 16HBE cells. Work is in its early stage, but it seems like these cells can polarize.

Thanks Jose.

In my hand too, they seem to form an epithelium. But after reaching a peak resistance of about 200 ohm*cm2, the epithelium starts to "degenerate", i.e. the resistance start to "slack off"...very quickly!

Do you have this same result?
