Migration of different B-cell subsets from bone marrow to human CCL4.
Chemotaxis of B cells from total bone marrow in response to serial dilutions of CCL4 (1-10 000 ng/mL) is shown. Results are expressed as the percentage (mean ± SD, n = 4) of the input cells that specifically migrated to CCL4. For comparison, chemotaxis responses of B cells to 100 ng/mL CXCL12 are shown.
