BQ-induced neutrophil expansion was blocked in c-myb-deficient mutants. (A–I) Expression of the neutrophil markers lyz (A,B) (sibling control group n=65, BQ group n=38; mutant control group n=25, BQ group n=35) and mpx (C,D) (sibling control group n=83, BQ group n=47; mutant control group n=31, BQ group n=16) was analyzed using WISH, and SB staining (E,F) (sibling control group n=54, BQ group n=18; mutant control group n=25, BQ group n=22) was detected, in c-mybhkz3/+ intercrossed progenies in BQ-treated groups (right column) and untreated controls (left column). Signals increased following BQ exposure at 3 dpf in siblings (A,C,E) but were unaltered in c-mybhkz3/hkz3 mutants (B,D,F). The red boxed regions show magnified views of the CHT. (G–I) Quantification of WISH and SB staining for panels A–F (Student's t-test, mean±s.d., **P<0.01, ****P<0.0001; ns, non-significant).
