LGALS1 and neoplasm: To ascertain that tumor dissemination was affected by fibroblast-secreted Gal-1, we co-cultured KM12C with either siGal-WS1 (KM+siGal-WS1) or with siC-WS-1 (KM+siC-WS1), and injected cells into the tail vein of C57BL/6 mice which were sacrificed after 24 hours to assess for tumor dissemination within the lungs.
