Figure 1. β₁ and β₂ integrin expression in the myeloid and lymphoid compartments of the bone marrow of JAK2^+/+ and JAK2^+/VF mice.

(A) β₁ integrin (CD29) expression and (B) β₂ integrin (CD18) expression in the myeloid (granulocytes and monocytes) and lymphoid (T and B cells) compartments of 10- to 12-week-old JAK2^+/+ (n = 10) and JAK2^+/VF (n = 11) mice. Data are shown as mean ± SEM. **P ≤ 0.01, ***P ≤ 0.001 (unpaired, 2-tailed Student’s t test).
