PLX increases the number of M1 TAM in the TME of 4T1 lung lesions. (A) a representative IF image acquired by confocal microscopy for total TAM (F4/80+), CD80+, and M1 TAM (F4/80+ CD80+ overlay), (B) impact of PLX (p.a.) +/− PTX (i.v.), 1 mg/kg each, on M1 TAM. Tumor nodules were collected from animal lungs (n=3) and six random images were taken on each group sample, pixels for M1 TAM were converted to area (1pixel = 0.98 μm2) and plotted in (B). PLX +/− PTX treated groups were compared with control and statistical significance was calculated by One-way ANOVA (*p <0.05, **p <0.01), data represented as mean ±SEM.
