CFTR inactivation by lentiviral vector-mediated RNA interference and CRISPR-Cas9 genome editing in human airway epithelial cells.
Polarized airway epithelial cell cultures modelling Cystic Fibrosis Transmembrane conductance Regulator (CFTR) defect are crucial for CF and biomedical research. RNA interference has proven its value to generate knockdown models for various pathologies. More recently, genome editing using CRISPR-Cas9 artificial endonuclease was a valuable addition to the toolbox of gene inactivation. ⋯ We generated CFTR inactivated cell lines and demonstrated that CRISPR-Cas9 vectorised in a single LVV efficiently promotes CFTR inactivation in primary HAECs. These results provide a new protocol to engineer CF primary epithelia with their isogenic controls and pave the way for manipulation of CFTR expression in these cultures.
