BM cells incubated with 4T1-TCM grouped with tumor-infiltrating myeloid cells, BM cells cultured in RPMI media clustered with splenic CD11b+ cells, and BM cells cultured with TCM and CCR1 and CCR5 antagonists associated with CD11b+ cells from the BM of naïve mice (figure 6A). Here, CCR5 is linked to neoplasm.
