NOTE: All pulmonary metastases were verified via histological examination when mice were sacrificed 2 weeks following palliative resection, or receiving BBS, Lenti-GFP, or Lenti-MTSS1. Lung metastatic extent was graded by number of tumor cells counted in the maximum section of the solitary pulmonary metastatic nodule. *P = 0.039 or 0.041 when Palliative Resection group or Lenti-MTSS1 group was compared among Control groups, respectively
