Fig. 5. Adhesion of TAM2D2 cells and C2B transfectants to rat embryo fibroblasts (REF) monolayers under flow conditions in the absence or presence of the CXCR4-blocking peptide TC14012. In the latter case, TAM2D2 cells and REF monolayers were both pre-incubated with the peptide. Results are given as the mean ± s.e.m. of the adhesion index, which is set to 1 for the control cells in each individual experiment. Shown are averages of four experiments.
