Plasma cells interact selectively with E-selectin.

Plasma cells and IgM⁺ B cells were analyzed for interactions with E-selectin (A) or P-selectin (B) transfected CHO cells in a parallel plate flow chamber, as described in “Materials and methods.” The data are represented as a mean percent control interactions ± SD (n = 3), with wild-type bone marrow cells serving as positive control. Asterisk indicates statistically different (P < .05) from IgM⁺ B cells; NS, not statistically different.
