Tumors grown in Mock CRC-injected mice had the highest number of myeloid cells (CD11b+ F4/80+) (Fig. 5F), while ~50% fewer myeloid cells/10,000 tumor cells infiltrated in tumors of Mock cell-injected mice treated with MMPi or in tumors of miR-126 OE-injected mice (Fig. 5H). This evidence concerns the gene ITGAM and colorectal carcinoma.
