CD11b staining and quantification.

Representative images of immunohistochemistry staining of CD11b in lungs of A. NSG mice. Images are from the three treatment cohorts (control, isoflurane, and ketamine) and contain representative high-power fields with inset low-power images of the entire tumor cross-section. Positivity mask in lower panels. Percent positive cells quantified over the entire area of lung cross-section of B. NSG mice. Mean ± SEM, n = 3 mice in each arm. One-way ANOVA, (F2,6 = 0.5066, p = 0.6262). p = 0.6667 and p = 0.5752 vs. control group.
