Figure 2: Effect of P2 receptor antagonists on cell migration of b.End3 cells. After Culture-Inserts were removed, cells were pretreated with apyrase (20 U/mL), PPADS (100 μM), oxATP (300 μM), A438079 (100 μM), 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.
