BCL2 and cancer: The cancer specimens were dissociated and then underwent a FAC-sorting for a pan-leukocyte-marker CD45 by flow cytometry to compare expression levels of Bcl-2 and miR-383 in inflammatory cells (including macrophages and lymphocytes) and in tumor cells, showing that the major source of Bcl-2 and miR-383 in GC tissue is tumor cells rather than inflammatory cells (Supplementary Figure).
