TiO2 NPs promoted tumor metastasis in vivo. a Schematic illustration of different treatments in tumor-bearing mice. b Volume of tumors treated with PBS or TiO2 during the period of 21 days post-tumor challenge. Data are presented as mean value ± SD (n = 6). c Hematoxylin/eosin (HE) images of lung sections of mice treated with PBS or TiO2. Scale bars = 500 µm. Data were quantified in (d) and (e). Number (d) and mean area (e) of pulmonary metastases in tumor-bearing mice. Data are shown as mean ± SD (n = 7). Statistical analysis was measured by one-way ANOVA
