Figure 5From: Electroporation increases antitumoral efficacy of the bcl-2 antisense G3139 and chemotherapy in a human melanoma xenograftProliferation index and apoptosis in M14 tumors treated with G3139 alone or in combination with EP. Tumors were excised from mice on day 4 after the end of treatment. Sections shown are as follows: Ki67 expression in tumors from animals untreated (panel A), treated with G3139 alone (panel B) or treated with G3139 in combination with EP (panel C); TUNEL staining in tumors from mice untreated (panel D), treated with G3139 alone (panel E), or treated by the combination (panel F).
