Representative immunohistochemical stainings.

<p>Tumor cell apoptosis (TUNEL, A and B), tumor microvascular density (CD31, C and D), and tumor cell proliferation (Ki-67, E and F) in the control (left column; A, C, and E) and the therapy group (right column; B, D, and F). Note the significantly higher apoptosis rate (B vs. A) as well as the significantly lower microvascular density (D vs. C) and proliferation (F vs. E) in the therapy group.
