ITGAM and neoplasm: To verify whether tumor growth inhibition was influenced by the immune cell composition within the TME we determined the frequencies of gr-MDSCs (CD11b+Ly6ClowLy6G+) and mo-MDSCs (CD11b+Ly6ChiLy6G−) subpopulations in the tumor mass of B16/CTRL, B16/PTGS2Δ, and B16/SCR-bearing mice.
