Correction to: Cellular & Molecular Immunology https://doi.org/10.1038/s41423-023-01106-w, published online 22 November 2023

In the sentence beginning ‘To trace cell proliferation, FO and MZ B cells’ and the sentence beginning ‘For cell activation, naïve B cells or CH12F3 cells’ in this article, the [10 ng/ml] ‘F(ab’)2 fragment goat anti-mouse IgM’ should have read ‘10 μg/ml F(ab’)2 fragment goat anti-mouse IgM’. The original article has been corrected.
