G3139 tumor accumulation after treatment alone or combined with EP. Mice were treated with G3139 labeled with 6-fluoroscein and six hours after treatment the tumors were excised. Results are as follows: Panel A, flow cytometric analysis of G3139 content in tumor cells from mice treated with EP (grey area) or G3139 (blank area) alone or in combination (dotted area). Panel B: representative sections of tumors from mice treated with G3139 alone (left) or in combination with EP (right). Original magnification × 20.
