FCGR1A and neoplasm: We show that two-marker analyses of Fc-γ receptor (CD64) and mannose receptor (CD206) expression on tumour-conditioned monocyte-derived macrophages (Mφs) could concurrently identify M1- and M2-like Mφ populations by flow cytometry through assessment of distinct, CD206loCD64hi and CD206hiCD64lo populations of CD14+ cells, respectively.
