Inhibition of S180 tumor growth.

<p>(A) SDS-PAGE identification of proteins. Lane 1, SEA; lane 2, EGF-SEA. (B) Effect of treatments on the growth of S180 tumors. After mice were inoculated with 2×10⁶ S180 cells into the right axilla, they were treated with two daily i.p. injections (0.2 ml) of 0.9% NaCl saline (control), SEA (250 pmol) and EGF-SEA (250 pmol) starting 1 day after tumor inoculation. n = 15 mice per group. *p<0.001. (C) Inhibition of S180 tumors. Mice were dissected and the tumors were measured on day 9. Yellow arrows indicated the tumor position. *p<0.001. (D) Effect of treatments on spleens.
