Time-course change of CCL19-induced dendritic extension of mature DCs.

BC1 cells were activated by LPS and used as mature DCs. The mature DCs were treated with CCL19 (20 ng/mL) for 15 minutes to 2 hours, and then the morphologic changes were analyzed by confocal microscopy (original magnification × 50). The results are representative of 3 independent experiments.
