As depicted in Figure 6E, CD45+CD11b+F4/80+ cells were isolated from single-cell suspensions of peritoneal fluid of MOVCAR 5009-bearing WT and TgMISIIR-TAg-Low mice by cell sorting (Figure S8) and injected i.p. (106 cells/mouse) into tumor-challenged WT mice 12 h before OV-CXCR4-A treatment. Here, CXCR4 is linked to neoplasm.
