We also found that CXCL12, CCL27, and CCL21 were found in higher quantities in the healthy adjacent tissue (1795.6 ± 700 pg/ml, 242.9 ± 95 pg/ml, and 17285.9 ± 6000 pg/ml, respectively) than in the tumor (325.8 ± 72 pg/ml, 56.7 ± 20 pg/ml, and 2313.6 ± 1,000 pg/ml, respectively) (Figure 4B). Here, CCL21 is linked to neoplasm.
