Fig. 9. In vivo therapeutic performance of PDA–MB in the suppression of cancer metastasis. (A) Schematic illustration of the experimental set-up for preventing lung metastasis. (B) Mouse survival rate after various treatments. (C) Quantitative analysis of lung metastatic nodules for each group. Data are shown as mean ± S.D. (n = 6). (D) H&E staining of the lung tissue collected at day 28. Scale bars = 200 μm. P values were calculated using two-tailed Student's t-test (***P < 0.001, **P < 0.01, or *P < 0.05).
