F. nucleatum -derived EVs enhanced BC cell viability and proliferation A. Morphology of the isolated F. nucleatum-derived EVs was observed under TEM. (Scalebar, 100 nm) B. Size distribution of Fn-EVs was analyzed by NTA. MDA-MB-231 and MCF-7cells were treated with PBS, F. nucleatum, or Fn-EVs (n = 3 per group) C. The cell viability was detected by CCK-8 after diverse treatments for 24, 48, and 72 h D. The cell proliferation was detected by Edu staining after 24 h (Scalebar, 100 μm). Data were analyzed using the one-way analysis of variance followed by Tukey’s post hoc test; ^**p < 0.01, ^***p < 0.001
