pLL₂₀/DNA complexes lead to increased levels of CR3-expressing cells within the liver of mice.

Method as for Figure 4. Briefly, mice were injected intravenously with pLL/DNA complexes, and liver sections were stained using antimouse CR3 antibody (nuclei, blue; CR3, pink). (A) pLL₂₀/DNA_ct (i); pLL₂₁₁/DNA_ct (ii); buffer alone (iii). (B) Average number of cells per field of view (200 × magnification) expressing high levels of CR3 pLL₂₀/DNA_ct (1), pLL₂₀/DNA_cp (2), pLL₂₁₁/DNA_ct (3), pLL₂₁₁/DNA_cp (4), DNA alone (5), or buffer alone (6).
