Compared to the oe‐NC+M2pep‐Cs NPs/Plerixafor group, the fluorescence intensity of CXCR4 in the tumor tissues of the oe‐CXCR4+M2pep‐Cs NPs/Plerixafor group was significantly increased; while, CXCL12 fluorescence intensity remained unchanged (Figure 7C,D). The gene discussed is CXCL12; the disease is neoplasm.
