Figure 2From: Cancer-associated fibroblasts are positively correlated with metastatic potential of human gastric cancersRealtime-PCR analysis of secreted proteins by CAFs in tumor and normal gastric tissues. Total RNA was extract and cDNA was prepared from surgically resected tumor and normal tissues from the same gastric cancer patients (100 cases). Realtime-PCR was carried out to compare the expression level of FAP (a), SDF-1 (b) and TGF-β1 (c) in tumor and normal tissues, the first two lanes of the electrophoretogram represented normal tissues and the last two lanes represented tumor tissues. *:p < 0.01.Back to article page
