Figure 1. Effects of LXA4 on cell viability and migration. HCECs were incubated with LXA4 at 0, 0.1, 1, 10, 100, and 1,000 nM for 24 h. CCK-8 assay showed the viability of HCECs was inhibited by LXA4 at concentrations of 100 nM and 1,000 nM. A: Cell scratch test and B: quantitative analysis C: of LXA4 on cell migration ability. 1 nM and 10 nM LXA4 promoted the migration of HCECs. The data were analyzed by unpaired, two-tailed Student t test and presented as mean ± SD (ns: no significance).
