Median percentage of CD20⁺CD27⁺CD43^lo–int or CD20⁺CD27⁺CD43^– cells expressing either CD5⁺, CD21^lo or IgM⁺ in healthy controls (n = 33). Whole blood was stained as stated in the Methods. Cells were gated as described in Fig. 2. Scatter graphs show individual percentage values for CD5⁺ (a), IgM⁺ (b) or CD21^lo (c) cells within the CD20⁺CD27⁺CD43^lo–int and CD20⁺CD27⁺CD43^– subpopulations.
