In terms of the first explanation, to investigate whether CXCL14 produced by mesenchymal-derived cells shows tumor-progressive effects, we employed mesenchyme-derived fibrosarcoma cells (MC57) and produced a stable cell line expressing CXCL14 (MC57-CXCL14) or control mock vector (MC57-MOCK). Here, CXCL14 is linked to neoplasm.
