Erratum for vol. 103, p. 2291

In the article by Abroun et al entitled “Receptor synergy of interleukin-6 (IL-6) and insulin-like growth factor-I that highly express IL-6 receptor α myeloma cells,” which appeared in the March 15, 2004, issue of Blood (Volume 103:2291-2298), the article title should have read “Receptor synergy of interleukin-6 (IL-6) and insulin-like growth factor-I in myeloma cells that highly express IL-6 receptor α.”

This title error was corrected online in departure from print.
