Comparison of the mean distribution scores (Y-axis) in the normal and tumorous tissues divided by the tumor subgroups, non-metastatic (N0T) vs. metastatic (N1T) (X-axis). Col1 (a) and Col4 (b) are significantly higher in the normal tissue. a-SMA (c) and MMP9 (d) are significantly higher in the cancer tissue. Black bars represent the normal tissue. Gray bars represent the tumorous tissue. **p <0.01, ***p <0.001
