Short-term changes in the immunoglobulin expression of B cells following rituximab treatment. Isolated bone marrow mononuclear cells were stained for immunoglobulin (Ig) expression at day 0, 1 and 3 months after rituximab treatment. In (a) CD19⁺IgD⁺, (b) CD19⁺IgM⁺, (c) CD19⁺IgG⁺ and (d) CD19⁺IgA⁺ is shown. Box represents 25^th to 75^th percentile, line indicates median, whereas error bars represent range. Statistical evaluation was performed using paired t-test.
