AE treatment inhibits growth of xenografted tumors <i>in vivo</i>.

<p>A. Top: Nude mice bearing tumors, left – control, right – treated. Bottom left. Size of tumors. Bottom right. Wet weight of tumor at 24 days of injection. B. Decreased immunohistochemical expression of Ki67 positive cells in mouse tumor xenograft after AE treatment. Histogram showing the decreased percentage of Ki67 immunopositive cells in AE-treated tumors. The tissue sections were photographed at 400X magnification. Bar=50 µm. The values are means <u>+</u> S.E.M. of 5 different mice. *, p<0.05, as compared with control group.
