1HAEo- is a human airway epithelial cell line that was immortalized with the origin-of-replication defective SV40 plasmid (pSVori-). The cell line retains characteristic features of normal differentiated airway epithelial cells including a cobblestone morphology, cytokeratin expression, the ability to form tight junctions and directional ion transport. It is unknown whether the donor had cystic fibrosis or not, however the cells do not contain the DeltaF508 mutation in the CFTR gene or other CFTR mutations presenting 98% of all CF mutations (1). CFTR sequence analysis revealed only wild-type CFTR sequences, supporting the conclusion that 1HAEo- are derived from normal (i.e. non-cystic fibrosis) tissue (1).
