Chemotactic preferences of CCL19 and CCL21 for murine DC line (BC1 cells).

BC1 cells were activated by LPS and used as mature DCs (mDC). Unstimulated BC1 cells were used as immature DCs (iDC). Numbers of migrated cells into the lower well are expressed as the percentage of input cells in the upper well at the start time of chemotaxis assay. Each symbol represents the mean ± SE of 4 or 5 independent experiments.
