Chemokine receptors expressed on Hodgkin lymphoma–derived cell lines represent fully functional receptors involved in chemotaxis.

(A-C) The number of HD cells that migrated at indicated concentrations of ELC (A), BCA (B), and SDF-1 (C) is given relative to the number of HD cells that migrated at medium control, which was set arbitrarily at 1 (chemotaxis index). Results represent mean values of 3 to 6 independent experiments, and errors are shown as SD.
