Ionic transport in tall columnar epithelial (TCE) cells obtained by nasal brushing from non-cystic fibrosis (CF) individuals.
Tall columnar epithelial (TCE) cells can be obtained by a non-invasive procedure through brushing the inferior turbinate and the adjacent lateral nasal wall.Here, we present results from the functional study of epithelial cells, thus obtained by using the patch-clamp technique.By patch-clamping the sub-apical region of TCE cells, we were able to id
