Evaluation of hematopoietic phenotype of Vegf^hi/+ and wt mice. Spleens from 8- to 10-week-old Vegf^hi/+ and age-matched wt controls (n ≥ 3 mice/group) were harvested and prepared for enumeration of B, T, and NK cells by flow cytometry as described in “Materials and methods.” (A) Percentage of B, T, and NK cells from spleens of Vegf^hi/+ and wt mice. **P < .05 when compared with wt control. (B) A representative dot plot of B220⁺ and CD3⁺ splenocytes from Vegf^hi/+ and wt mice that were evaluated by flow cytometry. (C) A representative dot plot of B220⁺ and CD19⁺ splenocytes from Vegf^hi/+ and wt control mice.
