Fig. 1. CCL19 is low-expressed in CRC tissue and negatively correlated with tumor angiogenesis.

a CCL19 expression level in tumor tissues and the paired normal tissues was evaluated by immunohistochemical staining with tissue microarray (scale: 200 μm). b CCL19 is lowly expressed in cancer tissues compared with normal tissues in tissue microarray. c CCL19 expression level and MVD (CD31-positive cell) in tumor tissues (scale: 200 μm). d Expression correlation of CCL19 and MVD was analyzed in 78 CRC patients (P = 0.0002). Data represent the mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001
