Inhibitory effect of NCTD on invasion of GBC-SD cells
. (A) Representative histomorphologic of GBC-SD cells (original magnification, ×200) with H & E staining under an optic microscope. (B) The invaded number of GBC-SD cells in control group, TIMP-2 group and NCTD group. The invaded number of GBC-SD cells in TIMP-2 or NCTD group was much less than that of control group (P < 0.001), without different CI between TIMP-2 group and NCTD group.
