Fig. 2: Serine and glycine control the migration process induced by the BEF.

The A549 and H1299 cells migrated to BEF (images in (A)) were counted and the results plotted in comparison with non-supplemented RPMI (B) (n = 3 for both cell lines). Images of A549 cells pretreated or not for 24 h with SARC and/or 4LFPG are shown in (C) and counted in (D). Data are mean ± SD (standard deviation) of three separate sets of biological experimental replicates. **P < 0.01; ***P < 0.005.
