Figure 1. Expression of CD9 on human tonsillar B cell subsets.

Figure 1

(A) Peripheral blood B cells and tonsillar B cells were stained with anti-CD9 (solid line) or isotype control antibody (dotted line). (B) Tonsillar B cells were further stained with anti-CD38 and anti-IgD, gated by the expression of these two markers, and the expression of CD9 on each subset was examined (PC, plasma cells; GC-B, germinal center B cells; NB, naive B cells; MB, memory B cells).
