FIG. 1.
ICAM-1 expression on vascular endothelial cells is upregulated after treatment (18 h) with culture supernatants from Ad-infected A549 cells or Ad-infected human corneal epithelial cells. (A) Endothelial ICAM-1 expression after 18-h exposure to culture fluids from Ad-infected A549 cells, mock-infected A549 cells, and medium alone (negative control; NC). (B) Endothelial ICAM-1 expression after 18-h exposure to culture fluids from Ad-infected human corneal epithelial cells, mock-infected A549 cells, and medium alone (negative control; NC). PC, positive control (vascular endothelial cells treated for 18 h with TNF-α [10 U/ml]). Data are from three to nine separate experiments with triplicate samples and are represented as the means ± standard deviations of the means. Significant differences from the mock sample are indicated by * (P < 0.05) and ** (P < 0.01).
