MOZ regulates proliferation and zonal formation within the GC. (A–D) GC B cells were assessed for DZ and LZ proportions using CD86 and CXCR4 to differentiate these zones by flow cytometry. (A) NP+FashiIgDlo B cells were assessed for zonal formation at day 7 postimmunization in Mb-1Cre/+ and Mozfl/flMb-1Cre/+. (B–D) Ratio of DZ to LZ GC B cells (B) and number of DZ (C) and LZ (D) GC B cells. Mb-1Cre/+, black bars; Mozfl/flMb-1Cre/+, white bars. Data are combined from three (day 7) and two (day 13) experiments; n = 5–10 per genotype. Error bars indicate ± SEM. *P < 0.05, **P < 0.01, ****P < 0.0001. (E and F) Cell-cycle analysis of day 7 sort-purified GC B cells from Mb-1Cre/+ (black bars) and Mozfl/flMb-1Cre/+ (white bars). Data are combined from two experiments; n = 6 per genotype. Error bars indicate ± SEM. *P < 0.05, **P < 0.01.
