Enhanced anti-tumor metastasis effect of Chl. coupled PDT in vivo. a, Experimental design to evaluate the anti-tumor metastasis effect on Balb/c mice (4T1 tumor cells). b, Photographs following WF are the white filed images of lung tissues after staining with Bouin's Fluid. Photographs in the middle are the panoramic scanning photographs of the H&E staining of lung tissues. Photographs below are the images of the H&E staining of liver tissues. (Scale bar = 100 μm) c, Quantification of metastatic lesions of the lung tissues. d, Quantification of metastatic lesions of the liver tissues. Each experimental group included n ≥ 3. Data are representative or pooled and are expressed as Mean ± SE. Asterisks indicate statistically significant differences as analyzed by One-Way ANOVA (∗∗∗ p < 0.001).
