Figure 3: Effect of P2 receptor antagonists on wound-healing of b.End3 cells. Cells were scratched and washed with medium. Scratched cells were treated with PPADS (100 μM), NF449 (10 μM), TNP-ATP (10 μM), 5-BDBD (10 μM), oxATP (300 μM), A438079 (100 μM), apyrase (20 U/mL), suramin (100 μM), MRS2578 (10 μM), NF157 (50 μM) or MRS2211 (100 μM), and incubated for 24 h. Pictures of the remaining gaps were taken with using a microscope.
