In mice, MDSCs specifically express Gr‐1 and CD11b, which are considered markers defining MDSCs.[11] This study showed that chronic inflammatory conditions mimicked by long‐term/low‐dose injection of LPS could induce tumor cells to highly express Gr‐1 and CD11b in B16 tumor‐bearing mice, which were named MDSC‐like tumor cells (MLTCs). This evidence concerns the gene ITGAM and neoplasm.
