Immune cells including Tregs, myeloid-derived suppressor cells (MDSCs) and lymphocytes that had infiltrated into the tumor microenvironment were analyzed by flow cytometry. Briefly, tumor tissues were digested with 2 U/mL dispase II and 100 μg/mL DNase I in PBS at 37 °C for 30 min to generate single-cell suspension. Cells were stained with antibodies, then analyzed by flow cytometry to identify immune cells.
