Fig. 2: Knockdown of OPN inhibits ICC growth and metastasis in vitro.

Knockdown of OPN significantly inhibited the a proliferation, b colony formation, c wound healing, d migration, and e invasion of HuCCT1 (left) and CCLP1 (right) cells, which were restored by shOPN-3-resistant OPN (shRES). Scr scrambled shRNA. All assays were performed in triplicate wells and repeated three times for each cell line, scale bar = 200 μm
