Figure 4. The effects of SALL4 on the migrated capacity of hepatic cancers. Distances of cell migration in HepG2 (A) and SMMC-7721 (B) HCC cells at 0 h, 24 hs and 48 hs after scratch, and the higher expression of SALL4 (mimic) decreased the scratch distance and the inhibited expression of SALL4 (inhibitor) increased the scratch distance after 24 and 48 hs. n = 3/group, t test between two groups, and by one-way analysis of variance among groups. *p < 0.05, **p < 0.01 vs. NC group.
