Evaluation of tumor inhibition by the protein vaccine/mesenchymal stem cells (MSCs) combined treatment. (a) Western blots probed with anti-E7-antibody from sera of the mice received the combined treatment. A negative correlation between the level of anti-E7 antibody and the tumor volume was observed. (b) TUNEL analysis of tumor sections obtained from the combined treatment and MSCs only treatment groups. TUNEL staining was shown in green and propidium iodide (PI) in red. The sample from the combined treatment contained more TUNEL-positive cells than the MSCs only group. (c) Quantification of TUNEL analysis (n = 6). Error bars represent SD among three independent experiments. *P < 0.05, compared with KP-hMSCs group.
