Number of migrated PMNL ing response to high levels of the chemokine IL-8 after BMECs were incubated with 0% TTO (control group), 0.05% TTO, in the presence of S. aureus and absence of TTO, or in the presence of S. aureus and 0.05% TTO in vitro. The media supernatants were from BMECs with different treatment, and added to the bottom wells of 24-well plates. The chambers were placed in the top of wells, and 100 μL PMNL suspension (5 × 105 cells/chamber) were seeded into the chambers. Data are presented as the means ± SEM (n = 3). Means at the different treatment with different letters (a-c) differ significantly for treatment effect
