Extended Data Fig. 6: Inhibition of 4T1 tumour metastasis by antigen-capturing bacteria.

a, Schematic of the therapeutic treatment to inhibit 4T1-tumour metastasis. b, Representative images of lung tissues fixed by Bouin’s solution. c, Panoramic scanning of H&E sections of lung metastases and the images of H&E slices in the liver. The black arrow indicates metastatic lesions in the lung and liver tissues. Scale bar, 1,000 μm. d, Quantification of metastatic lesions in lung tissues. e, Survival percentage of 4T1 tumour bearing mice after treatments. For the experiments in d, data are the mean ± s.e.m. (RT, RT + dB+, RT + B−, n = 7; Saline, n = 8; RT + B+, n = 6; biologically independent animals, two-tailed Student’s t-test).
