Transendothelial migration of FDCP-2 cells. (A) Transmigration of FDCP-2 cells through LE1SVO and STR cell lines; (B) effects of anti–VLA-4 and anti–VCAM-1 antibodies on the transmigration of FDCP-2 cells through STR-4 cells; (C) adhesion of FDCP-2 cells to STR-4 cells; (D) effects of anti–SDF-1 antibody on the transmigration of FDCP-2 cells through STR-4 cells. Results were shown as the mean ± SD of data obtained from three different experiments. *P < .01.
