Lentivirus-mediated shRNA interference targeting STAT3 inhibits human pancreatic cancer cell invasion

Figure 6 Invasion assay was performed using a specialized invasion chamber. A: The blue-stained cells are those that invaded the ECMatrix and migrated through the polycarbonate membrane to the lower surface of the membrane (original magnification × 200). B: Invasion assay indicated LV-STAT3siRNA significantly decreased the invasion ability of SW1990 cells. Bars indicate mean ± SD. ^aP < 0.05 vs SW1990 group, ^cP < 0.05 vs LV-Con group.
