Evaluation of HLA-DR−/lowCD14+ monocytic myeloid-derived suppressor cells (M-MDSCs) and HLA-DR+CD14+ monocytes/macrophages (MO/MA). Simultaneous analysis of myeloid cell populations in the a, b blood, c ascites and d tumour tissue of patients with ovarian cancer. Mononuclear cells (MCs) obtained from the blood (n = 43), ascites (n = 26), and tumour tissue (n = 29) of ovarian cancer patients and from the blood of healthy women (n = 15) were analyzed using flow cytometry. The levels of M-MDSCs and MO/MA are presented as the percentage of MCs. The horizontal lines are the median values and the whiskers indicate the minimum and maximum values. Each point corresponds to an individual patient. *p < 0.05; ***p < 0.001; ****p < 0.0001
