ITGAX and colonic neoplasm: To further delineate the effect of vancomycin treatment on CAC development, we evaluated the migration ability of myeloid cells such as neutrophils (Gr-1high/CD11bhigh), dendritic cells (CD11c+/CD11b+), and macrophages (F4/80+/CD11b+) to colon cancer induced by AOM/DSS treatment with or without vancomycin.
