Cytofluorimetric analysis of adhesion molecule surface expression. HUVEC were pretreated with DHZ or DHZ dimer and then treated with TNF-α 10 ng/mL for 6 hours. (a) and (b) show ICAM-1 and VCAM-1 expression evaluated as mean fluorescence intensity (MFI) (mean values of six experiments); (c) and (d) show ICAM-1 and VCAM-1 expression evaluated as percentages of positive cells (mean values of six experiments). Error bars represent SD. (a) ; ; ; . Medium versus TNF-α, . (b) ; °; ; . Medium versus TNF-α, . (c) . Medium versus TNF-α, . (d) ; . Medium versus TNF-α, .
