Immunohistochemistry staining of nasopharyngeal carcinoma (NPC) tissues (original magnification, ×200). (a) Positive expression of MIP-3α in NPC tissue. (b) Positive expression of cystatin A in NPC tissue. (c) Positive expression of CCR6 in NPC tissue. (d) Negative expression in NPC tissue as negative control. (e) Positive expression of MIP-3α in liver cancer tissue as positive control. (f) Positive expression of cystatin A in thymus tissue as positive control.
