The growth of xenografted tumours initiated by HSC-3 cells, which expressed CXCL14 in vivo and in vitro, was suppressed by the injection of cetuximab into tumour-bearing mice; however, neither the expression of the chemokine nor the cetuximab-dependent suppression of xenograft tumour growth was observed for YCU-H891 cells. Here, CXCL14 is linked to neoplasm.
