Cytotoxic effect of FGF7:EV complex on Caco-2 cells as displayed by the RTCA DP instrument. Cells were seeded overnight to reach the log phase, then incubated with 1.58 μM FGF7 (purple), media only (light-blue), FGF7:EV complex (contains 1.58 μM FGF7 and 3.26 μM EV) (dark-blue), FGF7:EV (contains 1.58 μM FGF7 and 6.52 μM EV) (green), or FGF7-EV (contains 1.58 μM FGF7 and 13.04 μM EV) (red). The IC50 value of the FGF7:EV complex was found to be 3.81 ± 0.82 μM after 96 h incubation time.
