Inflammatory infiltrates in mouse squamous cell carcinoma. The total number of leukocytes (A) and the number of cells expressing GR1 and F4/80 (B) were determined during the 4^th (4W), 8^th (8W) and 16^th (16W) weeks after DMBA protocol. Results are expressed as the mean ± SEM from each individual mouse analyzed (n=9 mice per group). *P< 0.05 and *** P< 0.001. Representative photomicrograph of GR1⁺ (green), F4/80⁺ (red) and IL-17⁺ cells (red) infiltrating tumour lesions. Representative tumour is shown. Blue, DAPI.
