Azab AK, Azab F, Blotta S, et al. RhoA and Rac1 GTPases play major and differential roles in stromal cell–derived factor-1–induced cell adhesion and chemotaxis in multiple myeloma. Blood. 2009;114(3):619-629.

On page 626, there is an assembly error in Figure 6B. The wrong tubulin blot was inserted for p-LIMK and p-cofilin during assembly. The corresponding author has provided a replacement tubulin blot and attests that all images are from the original experiments. This image assembly error does not affect the major conclusions of the study. The corrected Figure 6B is shown below.
