CXCR4, not CXCR3 and CCR10, was highly expressed in DSS-induced ulcerative colitis (UC) mice. A. The expression of CXCR3, CXCR4, and CCR10 were measured by immunohistochemistry 7 days after DSS-induced UC and control mice. B. Protein expression levels of CXCR3, CXCR4, and CCR10 were detected by western blot in DSS-induced UC and control mice. C. Densitometric quantification of protein levels of CXCR3, CXCR4, and CCR10 was performed and normalized to β-actin. **P<0.01 vs. control.
