Figure Lengend Snippet: Multiplexed ELISA of conditioned media from unstimulated umbilical artery (HUAEC), umbilical vein (HUVEC), dermal microvascular (HDMEC), and pulmonary microvascular (HPMEC) endothelial cells. Conditioned media was collected from 1 well per cell type after 16 hours incubation. Samples were analyzed with a Luminex Magpix device and a custom ProcartaPlex inflammation panel. Data are represented as (A) Heatmap normalized across the range for each protein, with darker tones corresponding to higher expression and less expression for lighter tones. Factors that measured below the limit of detection are indicated with an X. (B) log 10 (average expression) ± SEM for N=4 independent experiments. Factors that measured below the limit of detection are indicated with an X. Full statistical analysis with one-way ANOVA and Tukey-Kramer pairwise comparisons testing was done for average expression across all cell types, with results presented in Supplemental Figure 1.

Article Snippet: The following cells were used: pooled human umbilical vein endothelial cells (HUVEC, PromoCell C-12203, Heidelberg, Germany), human umbilical arterial endothelial cells (HUAEC, PromoCell C-12202, Heidelberg, Germany), adult dermal microvascular endothelial cells (HDMEC, PromoCell C-12212, Heidelberg, Germany), and adult pulmonary microvascular endothelial cells (HPMEC, PromoCell C-12281, Heidelberg, Germany).

Figure Lengend Snippet: Multiplexed ELISA of conditioned media from TNF-stimulated (50ng/mL TNF in media) umbilical artery (HUAEC), umbilical vein (HUVEC), dermal microvascular (HDMEC), and pulmonary microvascular (HPMEC) endothelial cells. Conditioned media was collected from 1 well per cell type after 16 hours incubation. Samples were analyzed with a Luminex Magpix device and a custom ProcartaPlex inflammation panel. (A) Heatmap normalized across the range for each protein, with darker tones corresponding to higher expression and less expression for lighter tones. (B) Fold-change expression differences from unstimulated control for factors with >8 fold increase by at least one cell type. Data are average fold change-expression for N=4 independent experiments. One-way ANOVA with Tukey-Kramer pairwise comparisons testing was done for each condition, with asterisks indicating statistical significance between conditions (*p<0.05).

Figure Lengend Snippet: Endothelial cells were cultured in 96-well plates and activated with control, TNF(50 ng/mL) or P. aeruginosa (0.05 OD) media for 2 hours. Neutrophils isolated from whole blood were added to each well and incubated for 15 minutes, then imaged before and after 5x PBS washes. (A) Representative images of endothelial cells (red) and neutrophils (green) before and after washing to remove non-adherent cells. (Scale bar = 100 μm) (B, C) Neutrophil adhesion fraction was quantified by counting neutrophils adherent after washing and dividing by the neutrophil count before washing. Data represent average adhesion fraction ± SEM for 3 independent experiments per cell type. One-way ANOVA with Tukey-Kramer pairwise comparisons testing was done for each condition, with asterisks indicating statistical significance between conditions (*p<0.05).
