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 small airway epithelial cells (HSAECs) (PCS-301-010) were obtained from ATCC and cultured in Airway Epithelial Cell Basal Medium (ATCC) containing a Bronchial Epithelial Cell Growth Kit (ATCC) and penicillin-streptomycin (100 U/mL, 100 μg/mL).

Figure Lengend Snippet: DSG-PEG2000 turbidity assessment, mucus penetration potential of DSG-PEG2000, and toxicity analysis of DSG-PEG2000 on human respiratory epithelial cells. (A) Turbidity measurement of normal saline, DSG-PEG2000, and chitosan oligosaccharide lactate solutions added to 0.5% porcine mucin II solution, with significance indicated. Error bars represent the standard error of the mean values (* indicates significant difference (p < 0.01), n=3). (B) Visual schematic of artificial mucus layer penetration study (figure created with PowerPoint). (C) Mean absorbance of Nile red in the agarose layer due to mucopenetration. The red line indicates significance between the timepoint 2 hr group. Blue line indicates significance between the timepoint 4 hr group. The green line indicates significance between the timepoint 6 hr group. Error bars represent standard deviation (* indicates significant difference (p < 0.01)). (D) Viability of hSAEC cells following incubation with blank nanoemulsion at concentrations of 20, 40, 60, 80, and 100% (v/v).

Article Snippet: Recombinant human (rh)IL-2 and rhIL-15 were obtained from the Biological Resources Branch (National Cancer Institute, Frederick, MD) and recombinant murine IL-15 was purchased from R&D Systems (Minneapolis, MN). hSAEC primary small airway epithelial cells (Cat #PCS-301-010), NK-92 human NK cell lymphoma (Cat #CRL-2407), MG63 human osteosarcoma (Cat #CRL-1427), and K7M2 murine osteosarcoma (Cat #CRL-2836) cell lines were all obtained from ATCC (Manassas, VA).

Techniques: Saline, Standard Deviation, Incubation
