LPA2-dependent cell migration was inhibited by a PLC-β inhibitor.
A, frequency of LPA-induced Ca2+ puffs in DKO-LPA2 MEFs treated with PLC-β inhibitor U73122 (2 μm) or its inactive analog U73343 (2 μm). B, kinetics of the relative wound density in the presence of U73122 (2 μm), U73343 (2 μm), or either U73122 or U73343 plus LPA (1 μm). The data were analyzed using IncuCyteTM software. C, the migration of DKO-LPA2 MEFs at the basal or LPA-activated state with U73122 (2 μm) or U73343 (2 μm) treatment. Error bars, S.E.
