CCL21 and head and neck squamous cell carcinoma: We observed that both Cis-Pt and SLC-0111 reduced cell migration at 24 h when used as single agents in both HNSCC cell lines, with a greater effect in SCC-011 cell line, in comparison with untreated cells (FaDu: reduction of 31% and 50% after Cis-Pt and SLC-011 treatment, respectively; SCC-011: reduction of 46% and 59% after Cis-Pt and SLC-011 treatment, respectively; (p < 0.0001) (Fig. 3A and B).
