The schematic presentation of the experimental process of bacterial taxis. (A) The two-chamber device used for the experiments. (B) Normal and cancerous cells were cultivated for 48 hr in separate chambers. (C) GFP-encoding bacteria were injected into the central channel allowing interaction with the diffused biochemical factors from chambers of cell culture. (D) Preferential accumulation of bacteria was quantified in the analysis region by fluorescence intensity of GFP encoding bacteria.
