STAT3-mediates PAK4-induced stemness in PC cells. (A) The expression of stem cell markers was analyzed by immunoblot analysis. β-actin was used as an internal control. (B) After transfection, cells were cultured in ultra-low attachment plate to analyze the effect of STAT3 on sphere-forming potential of these cells by sphere forming capacity. Sphere >50 μm in diameter was counted at 200× magnification (mean ± SD; n = 3, *p < 0.05).
