Furthermore, HT‐DNA‐treated MCF7/ZR75.1 cells significantly increased the percentage of DCs (CD11c+, CFSE+) that engulfed CFSE‐labeled tumor cells when the tumor cells were cocultured with DCs, while HT‐DNA‐treated R‐MCF7/R‐ZR75.1 cells slightly increased the percentage of DCs that engulfed CFSE‐labeled tumor cells (Figure 3D; and Figure S3C,F, Supporting Information). Here, ITGAX is linked to neoplasm.
