Inhibitory effect of NCTD on migration of GBC-SD cells in vitro. (A) Representative pictures of collagen gel contraction of GBC-SD cells. (B) Comparison of collagen gel contraction of GBC-SD cells in different groups: A significant difference of gel contraction index (CI) of GBC-SD cells was observed between control group and TIMP2 or NCTD group from 1 to 4 days (*P < 0.01, vs. TIMP2 or NCTD group), without different CI between TIMP-2 group and NCTD group.
