Epithelial tightness of fully differentiated CF cell cultures. Relative fluorescence intensity of FD-4 in the basal chamber was assessed at 4 h after apical addition of FD-4 on submerged and 1 to 24 days ALI cultures of primary CF nasal epithelial cells. Values were expressed as % of fluorescence relative to control (empty insert without cells and with medium only). Data are presented as mean of 1–10 different CF patients. Statistical analysis was done in comparison to submerged cultures. *: p < 0.05, **: p < 0.01
