  1. Human nasal epithelial cells (HNEC) from control (non CF) and CF patients were grown for 14 to 21 days on semi-permeable transwell filters until transepithelial resistance developed. Transwell filters were mounted in Ussing chamber for measurement of voltage (PD) and short-circuit current (I sc). Transepithelial resistance (R te) was calculated with Ohm's law from I sc and PD. Results represent means ± SE of 25 individual filters from 9 separate cultures of non CF HNEC, and of 9 individual filters from 4 separate cultures of CF HNEC.
  2. **, ***: significantly different from corresponding value in control HNEC group (P < 0.01 and P < 0.001, respectively).
