Figure 4. T cells activated by DC/EC fusion impact tumor apoptosis, proliferation and endothelial cell expression in vivo.

(a) TUNEL expression in tumor tissues and quantitation of its expression. (b) Ki-67 expression in tumor tissues and quantitation of Ki-67 expression. (c) CD105 expression in tumor tissues. (d) HE staining of mice organs to determine toxicity of tissues. Scale bars = 100 μm in a, = 50 μm in b and d, = 200 μm in (c). **P < 0.01, ***P < 0.001.
