The percentage of tumor specimens which was positive or negative for CAFs' prevalence in the group of patients with or without tumor metastasis. The tumor specimens were grouped according to whether or not the gastric cancer patients had tumor metastasis (whatever lymph node metastasis, distant metastasis or organ metastasis). And the percentage of the specimens which was positive (grade - or + according to immunochemical staining) or negative (grade ++ or +++ according to immunochemical staining) for CAFs' prevalence was analyzed (a). And the immunochemical staining of α-SMA was shown in normal gastric tissue, gastric cancer tissue without metastasis and gastric cancer tissue with metastasis (b).
