Fig. 5.
Comparison of migratory capacity of tumor cells dissociated from the peripheral (external), middle (between the periphery and the center of the tumor) and internal portions of the tumor. (A, B) Images of nude mice with tumors and excised tumor. (C) Images of carcinoma specimens collected by puncture needle. (D) The viability of cancer cells collected from external, middle and internal positions of the tumor. (E, F) Comparison of the migration distances and percentages of migrating cells collected from different depths of tumor. Data in the bar graph were analyzed in the same condition as Figure 1D.
