HUVECs in single-cell suspension in PBSA-EDTA
were treated with preincubated 40 M apple dp4 or 40 and
400 M EGCG and 1 g/mL biotinylated VEGF for 30 min at 4C.
Then avidin-FITC was added and the cells were incubated for a
further 30 min at 4C in the dark. Bars represent means ± SD
expressed as a percentage of FITC intensity after normalisation.
***p < 0.001 compared to their respective controls. Data are expressed
as mean ± SD (n = 8)
