FIGURE 2.

EA repressed colorectal tumor growth in vivo. (A) After experimental mice were sacrificed, the xenograft tumors (marked with red dotted lines) were photographed in vivo. (B) The tumor weight and mice body weight were measured and recorded. The difference was calculated by a two-way t-test, *p < 0.05, NS means no significant difference. (C) The EA-treatment xenograft tumors and control xenograft tumors were stained using H&E. (D) Immunohistochemistry (IHC) was used to detect Ki67 in both EA-treatment group and control group, and the stained slides were photographed by a microscope. (E) The mice kidneys in EA-treatment group and control group were stained with H&E dye. (F) The mice livers in EA-treatment group and control group were stained with H&E dye. (G) The mice hearts in EA-treatment group and control group were stained with H&E dye.
