Reagents:

… Lipopolysaccharide (LPS) was obtained from List Biological Laboratories (Campbell, CA). TNF-, IL-1, and IFN- were used separately, as a mixture (referred to as CytoCombo), or as a mixture of CytoCombo and LPS (CytoCombo + LPS)

Fractionation of endothelial cell-derived extracellular vesicles (E-EVs):

Ten-centimeter dishes coated with type I collagen (BD Biosciences, San Jose, CA) of confluent b.End5 cells were rinsed with PBS, and stimulated with medium containing CytoCombo + LPS, CytoCombo, or LPS alone to induce inflammation.

Scanning electron microscopy:

Endothelial b.End5 cells were seeded on cover slips and cultured until confluent. Confluent cells were then exposed to inflammatory stimuli (CytoCombo + LPS) for 10 seconds or 10 minutes. After stimulation, the cells were fixed with 2% formaldehyde…

Western blotting:

For E-EV marker analyses, E-EVs that were fractionated from the culture media of b.End5 cells after CytoCombo + LPS stimulation were used as sample.

Materials and Methods:

Animals – All experiments were performed according to international guidelines and approved by the local experimental animal committee of the University Medical Center Utrecht (DEC-ABC, Utrecht). On postnatal day 9 (P9), C57Bl/6 mice pups were anaesthetized with isoflurane (4% induction, 2% maintenance), the right common carotid artery was occluded by thermo-cauterization, xylocaine (100 mg/ml; AstraZeneca, Zoetermeer, The Netherlands) was applied and the incision was closed. After a minimal 1 h recovery, the pups were exposed to 10% O₂ in N₂ for 45 min and returned to their dams. Sham-control animals underwent anesthesia and incision only. LPS+HI or LPS+sham control animals received an intraperitoneal (i.p.) injection of LPS (List Biological Laboratories, Campbell, Calif., USA) at a dose of 0.5 mg/kg 14 h before surgery. …
