Activation of TLR3 promotes migration of PTC in vitro. A. Representative Transwell migration assay shows significant improvements in cell mobility upon activation of TLR3. 3×10⁴ K1 cells were implanted into the upper chamber of the well and treated with 10 μg/mL poly I:C, 1 μg/mL LPS or PBS as controls. B. Quantization of Transwell migration assay was counted in a blinded fashion by light microscopy at 20× magnification. Data is representative of three independent experiments. **, P<0.01.
