Figure Lengend Snippet: Cell viability of HDF cells treated with Ch NPs at concentrations of 2.5–160 µg/mL for 24 h. Viability was determined using the MTT assay and expressed as mean ± SE (n = 3). Different letters indicate statistically significant differences ( p < 0.05).

Article Snippet: The biocompatibility of Ch NPs was evaluated using primary HDF (ATCC ® PCS-201-012TM [ ], American Type Culture Collection, Manassas, VA, USA) and HaCaT cells (Cat. No. T0020001, AddexBio, San Diego, CA, USA).

Figure Lengend Snippet: A Human lung smooth muscle cells (HLSMCs), lung fibroblasts (HLFs), and small airway epithelial cells (HSAECs) were treated with TFP at the indicated concentrations for 24 h. Human peripheral blood eosinophils and neutrophils were treated with TFP for 2 h. Cell viability was assessed by staining the cells with Annexin V (AnnV) and DRAQ7. Viable cells, AnnV − DRAQ7 − ; apoptotic cells, AnnV + DRAQ7 − ; necrotic/late apoptotic cells, AnnV + DRAQ7 + . HSAECs, n = 6 from three independent experiments; HLSMCs, eosinophils, neutrophils, n = 4 from four independent experiments; HLFs, n = 3 from one individual experiment representative of three independent experiments (One-way ANOVA for HLSMCs, HLFs; Kruskal-Wallis for HSAECs; Friedman test for eosinophils, neutrophils). B – C Bone marrow-derived MCs (BMMCs) and peritoneal cell-derived MCs (PCMCs) treated under the same conditions as in ( A ) for 24 h. BMMCs, n = 5 from two independent experiments; PCMCs, n = 3 from one individual experiment representative of three independent experiments (One-way ANOVA). Untreated (control) cells were used for statistical comparisons to all other groups in all figures. The bar charts show mean values + SEM or median + interquartile range. * P < 0.05; ** P < 0 .01; **** P < 0.0001. D Effect of TFP on DNA degradation. MCs were preincubated with bafilomycin A1 (Baf A1) (20 nM) for 2 h followed by treatment with TFP (10 μΜ) for 2 h. DNA was extracted from MCs and fragmentation was assessed by agarose gel electrophoresis. St standard marker.

Article Snippet: Primary human lung fibroblasts (HLFs) (PCS-201-013) and primary human lung smooth muscle cells (HLSMCs)(PCS-130-010) were obtained from American Type Culture Collection (ATCC, Manassas, VA) and cultured following the manufacturer’s instructions.
