Different responses to SDF-1 of peritoneal versus spleen B2 lymphocytes.

The response to SDF-1 of peritoneal (black columns) and spleen (gray columns) B2 lymphocytes was evaluated for chemotaxis (A,B), proliferation (C,D), and survival (E,F). In each case, the influence of IL-10 (left panels) or anti–IL-10R Ab (right panels) on this response was tested. Results shown are from 1 of 2 (C-F) or 3 (A,B) experiments.
