Combined effect of cNPs and RAW264.7 cells on the proliferation of colon26/fluc cells. (A) Co-incubation of RAW264.7 cells with colon26/fluc cells with or without cNPs. After 24 h-incubation, cells were lysed, and luciferase activity was measured. Results are expressed as the mean ± SD of three samples. *p < 0.05 vs. without cNP (no treatment) group. (B) Colon26/fluc cells were seeded onto the bottom of Transwell, and RAW264.7 cells with or without cNPs were added to the insert well (upper bottom). After 24 h-incubation, colon26/fluc cells were lysed and luciferase activity was measured. Results are expressed as the mean ± SD of three samples. *p < 0.05 vs. control group.
