Figure 11: CCL interactions with Caco-2 cells at increasing incubation times. Representative fluorescence images of Caco-2 cells with CF loaded CCLs at increasing incubation time. Incubation times of 30 min (A), 6 h (B) and 24 h (C) are shown. Rows show from left to right untreated cells (left) and cells treated with CCL-R5, CCL-R10 and CCL-R20. Fluorescence signals are overlaid on transmitted light (DIC) images. Scale bar indicates 50 μm.
