Clinical and prognostic significance of CC chemokine receptor type 8 protein expression in gastrointestinal stromal tumors

Figure 1 Immunohistochemical staining for CC chemokine receptor type 8 in gastrointestinal stromal tumors. A1: High cytoplasmic staining of CC chemokine receptor type 8 (CCR8) in the tissue microarray samples; A2: Specific high positive staining for CCR8 in the cytoplasm; B1: Low cytoplasm staining of CCR8 in gastrointestinal stromal tumor tissues; B2: Specific low positive staining for CCR8 in the cytoplasm; C1 and C2: Negative staining for CCR8. Original magnification: A1, B1, C1 × 40; A2, B2, C2 × 400.
