Figure Lengend Snippet: Transfection capacity and cell viability assays. ( A ) Fluorescence intensity over time in CuFi-1 cells transfected with nioplexes based on formulation 1 , 2 and 3 at cationic lipid/DNA mass ratio 5/1. Each value represents the mean ± SD of three measurements. ( B ) Fluorescence microscope images showing EGFP positive CuFi-1 cells transfected with nioplexes based on formulation 1 , 2 and 3 at cationic lipid/DNA mass ratio 5/1 and cellular appearance over time. ( C ) Percentages of EGFP positive live cells (bars) and cell viability (symbols) measured by flow cytometry in CuFi-1 cells 48 h after transfection with nioplexes 1 and 2 at cationic lipid/DNA mass ratios 2/1, 5/1 and 10/1. Each value represents the mean ± SD of three measurements. ( D ) Mean fluorescence intensity values. Each value represents the mean ± SD of three measurements. Statistical significance: * p ≤ 0.05 in transfection and MFI; # p ≤ 0.05 in cell viability.

Article Snippet: Human cystic fibrosis airway epithelial (CuFi-1) cells obtained from ATCC ® CRL-4013™ were incubated at 37 °C and 5% CO 2 atmosphere in collagen type IV (Merck KGaA, Darmstadt, Germany) pre-treated flasks/plates and were split every 2–3 days to maintain monolayer coverage.
