Comparison of PM between SP-D KO and control mice. (A) CT scan analysis shows that a significantly greater number of pulmonary metastases were present in SP-D KO mice than C57BL/6 mice (1.63 vs. 1.22; P=0.045). The data shown are mean ± SD. *P<0.05 compared with the control. (B) Pathological examination showed that a significantly greater number of pulmonary metastases were present in SP-D KO mice than in C57BL/6 mice (2.21 vs. 1.61; P=0.019). The data shown are mean ± SD. *P<0.05 compared with the control. SP-D, surfactant protein D; PM, pulmonary metastases; KO, knockout.
