As EpCam+ tumor cells expressed G‐CSF in GC tumors (Figure 5H), we isolated EpCam+ cells from tumor and non‐tumor tissues of autologous GC patients, and cultured them to obtain tumor cell culture supernatants and non‐tumor cell culture supernatants, then stimulated neutrophils with these supernatants. The gene discussed is CSF3; the disease is neoplasm.
