Treatment of bone marrow cells with α-toxin decreases TER119+ erythroblasts. Bone marrow cells were isolated from mice, and flow cytometry analysis was performed using a Guava easyCyte. (A,B) A total of 5 × 106 bone marrow cells were cultured for 24 hours in the presence of the indicated concentration of α-toxin (Wild-type) or a variant α-toxin (H148G). The frequency (A) and absolute number of TER119+ cells per culture well (B) are shown. (C,D) Bone marrow cells were cultured for 3, 6, or 24 hours in the presence of 10 ng/ml α-toxin (Wild-type) or a variant α-toxin (H148G), and the frequency (C) and absolute number of TER119+ cells per culture well (D) are shown. One-way ANOVA was employed to assess statistical significance. Values are mean ± standard deviation. *P < 0.05; **P < 0.01; n.s., not significant.
